The transfer window does not close. It slams shut, and on Tuesday, it slammed shut with a flurry of late activity.

LaLiga champions Atletico Madrid were heavily involved, with Antoine Griezmann re-joining the club on loan from Barcelona while Saul Niguez left for Chelsea.

It marked the end of a difficult window for Barca, who of course lost Lionel Messi to Paris Saint-Germain, who rounded off a stellar three months by not only keeping Kylian Mbappe, but also adding promising left-back Nuno Mendes.

Earlier in the day, Cristiano Ronaldo's sensational return to Manchester United had been confirmed, perhaps putting the Red Devils right in the mix for the Premier League title, while Chelsea - buoyed by Romelu Lukaku's comeback - cannot be ignored.

Here, Stats Perform looks at the winners, and losers, of what has been a chaotic transfer window.

THE WINNERS

Paris Saint-Germain

Let's start with the obvious. Achraf Hakimi, Mendes, Sergio Ramos, Gianluigi Donnarumma, Georgino Wijnaldum and, of course Messi. Oh, and PSG kept hold of Mbappe, too, rebuffing three bids - the final one reportedly worth €200m - from Real Madrid for the 22-year-old superstar who is out of contract next year. Speaking of out of contract players, Ramos, Donnarumma, Wijnaldum and Messi were all brought in for combined fees of €0, although their wages are sure to be astronomical even by PSG's standards. In Mbappe, Neymar and Messi, PSG have, on paper, what could be the most feared attacking trident of the modern era, not to mention Angel Di Maria in reserve. Mauricio Pochettino's side look suspect defensively but have Ramos to come in, while Donnarumma will compete with Keylor Navas. If they do not win the Champions League this season, will they ever manage it?

Manchester United

It remains to be seen whether United really needed to go out and buy Ronaldo, but the temptation – and reportedly, the requirement to get one over on noisy neighbours Manchester City – was just too much. However, there is no doubting Ronaldo brings a focal point you could argue was still missing from the Red Devils' attack, though with so much quality at his disposal the pressure will be on Ole Gunnar Solskjer to deliver a trophy. United spent big on Jadon Sancho and also brought in a world class defender in Raphael Varane. A title tilt might not be expected just yet, but silverware in some form must be the goal now. After fan protests during the botched Super League proposals earlier this year, the Glazer family seem to have gone all out to prove they want success.

Chelsea

When it comes to Premier League title contenders, Chelsea have surely put themselves well in the running. The European Champions have brought in two major additions in the form of Lukaku and Saul, both players with a wealth of experience at the highest level, and both on the back of title-winning campaigns last season. The Blues did sell Tammy Abraham, Olivier Giroud and Kurt Zouma, among others, but the strength in depth Thomas Tuchel has to play with is remarkable. A deadline day move for Sevilla's Jules Kounde did not materialise, but Saul adds another fantastic option in midfield to go alongside N'Golo Kante, Mateo Kovacic and the in-form Jorginho.

Tottenham

For a long while, it looked as though Tottenham would be one of the big losers from this window. A prolonged managerial search eventually resulted in Nuno Espirito Santo's appointment, but the main saga was over Harry Kane's future. City reportedly made one bid, during Euro 2020, which was dismissed out of hand. The champions never did return with an improved offer, despite huge speculation, and Kane ultimately stayed put. Older players such as Joe Hart, Toby Alderweireld, Erik Lamela and Moussa Sissoko were moved out, while Bryan Gil, Pierluigi Gollini, Cristian Romero and Emerson Royal – a deadline day arrival from Barca – arrived to fill the gaps. Serge Aurier's contract was terminated, while three wins from three means Spurs sat top of the league heading into the international break.

Atletico Madrid

While Saul was a deadline day exit, Atleti have given themselves a great chance of retaining their LaLiga title. With rivals Madrid failing to land Mbappe, as well as losing two of their stalwarts, and Barca seemingly in disarray, there has never been a better opportunity for Diego Simeone's team to really assert themselves as top dogs in Spain. Griezmann's arrival, on a season-long loan with the option for either club to extend the switch, has bolstered a fearsome attack that already included Luis Suarez, Angel Correa, new signing Matheus Cunha and Joao Felix - though the latter may now find chances to play in his preferred position, nominally off the front man, even harder to come by. Saul was struggling to nail down a regular spot in the first team, but Atleti showed greater desire to keep Kieran Trippier, who stayed despite interest from the Premier League. Rodrigo de Paul also arrived from Udinese.

THE LOSERS

Barcelona

The chickens have finally come home to roost at Camp Nou. Years of mismanagement, and the impact of COVID-19, has left the club's finances in a shambolic state. Barca had agreed to a new deal with Messi only to then announce the deal could not be completed due to "financial and structural obstacles". Barca ended the window by selling promising youngster Ilaix Moriba to RB Leipzig and shipping off Emerson to Spurs. Then, late on Tuesday, Griezmann, who cost Barca €120m in 2019, was sent back to Atleti. Luuk de Jong, a target man Ronald Koeman worked with during his stint as the Netherlands' coach, was drafted in from Sevilla as a replacement. Memphis Depay seems ready to step up after his arrival from Lyon, while Eric Garcia and Sergio Aguero also came in on free transfers, though Gerard Pique, Sergi Roberto, Jordi Alba and Sergio Busquets were among the players who took pay cuts in order for Barca to register their latest acquisitions.

Inter

Serie A champions Inter were dealt a blow when, just after ending their 11-year trophy drought, coach Antonio Conte left the club. Financial difficulties meant the Nerrazurri had to cash in on prized assets, and Hakimi and subsequently Lukaku followed Conte out of the door. Lautaro Martinez did stay, however, with Inter reinvesting some of the funds to sign Netherlands right-back Denzel Dumfries, Roma striker Edin Dzeko and Lazio forward Juan Correa. Hakan Calhanoglu, meanwhile, joined from rivals Milan on loan, though it is difficult to see that being enough for Inter to challenge on all fronts this season.

Juventus

While Inter were weakened, it has to be said that Juventus – surely their closest rivals in the Scudetto hunt – also had a disappointing window. Like many European clubs, they have been hit hard by COVID-19, though appeared well set to challenge again after reappointing Massimiliano Allegri. However, Ronaldo decided he wanted out late in the window, and Juve did not stand in his way. An initial fee of £12.86m (€15m), payable over five years, was agreed with United, and Ronaldo left just like that. Moise Kean returned from Everton on a two-year loan with an obligation to buy as a replacement, while Manuel Locatelli was their other major acquisition and Weston McKennie's move from Schalke was made permanent. Based on the performance in Sunday's defeat to Empoli, however, Juve are far from the force they were during Allegri's last spell in charge.

Real Madrid

For a time last week, it really did look as though Madrid were going to end the window in sensational fashion. Three bids were lodged for Mbappe, but PSG did not buckle. Madrid did move for another French youngster – Edouardo Camavinga, who joined from Rennes on Tuesday – but overall it must be considered a poor window. Los Blancos allowed Ramos to leave on a free and sold long-time defensive partner Varane - just the eight Champions League winners' medals between them. Martin Odegaard was deemed surplus to requirements by Carlo Ancelotti and sold to Arsenal, though no buyers were found for fringe players Luka Jovic or Dani Ceballos. David Alaba's arrival on a free transfer from Bayern Munich at least softened the blow of Ramos' departure, and Mbappe may well be on board in 2022.

Manchester City

City broke the British transfer record to sign Jack Grealish from Aston Villa, who in turn have made smart acquisitions such as Danny Ings, Leon Bailey and Emiliano Buendia. While another attacking midfielder was more of a luxury than a necessity, City did miss out on Kane and then seemingly saw Ronaldo snatched from under their noses by United, though the club have claimed it is they who pulled out of the deal. Pep Guardiola went into the window wanting an out-and-out number nine following Aguero's departure, but for now the Premier League champions will have to carry on with makeshift forwards, it seems. Not that it did them much harm in 5-0 routs of Norwich City and Arsenal last month. Meanwhile, wantaway playmaker Bernardo Silva is still at the club, though he will remain a first-team regular.

Liverpool 

Unlike their league rivals, Liverpool never seemed focused on spending big. The Reds instead turned their attention to tying down the futures of key players, with Jordan Henderson, Virgil van Dijk, Trent Alexander-Arnold, Alisson, Fabinho and Andrew Robertson signing new deals. Ibrahima Konate came in from RB Leipzig to boost the defence – a clear area of weakness last season during an injury crisis – though Jurgen Klopp's squad does seem weaker. They have started the season well, but it remains to be seen how they cope without Wijnaldum and even Xherdan Shaqiri should injuries trouble them again.

The transfer window officially closed on Tuesday, meaning clubs across Europe must now make do with the players available to them until at least January.

It has been an eventful few months, with Lionel Messi ending his 21-year association with Barcelona by joining Paris Saint-Germain and Cristiano Ronaldo sealing an emotional return to Manchester United from Juventus.

The drama continued to unfold right through until the final stages of the window as Antoine Griezmann rejoined Atletico Madrid on an initial loan and Chelsea snapped up Saul Niguez from the Spanish champions, while Real Madrid brought in rising star Eduardo Camavinga from Rennes.

With Kylian Mbappe staying at PSG and Harry Kane still a Tottenham player, Jack Grealish's £100million switch to Manchester City from Aston Villa was the biggest deal in monetary terms, followed by Romelu Lukaku's £97.5m (€115m) move to Chelsea from Inter.

Stats Perform takes a look at the best deals that went through.

Hakan Calhanoglu: Inter to Milan (free transfer)

After failing to agree new terms at Milan, Calhanoglu completed a shock move across the city to rivals Inter, signing a three-year deal.

While not necessarily the most popular transfer, getting a player who created 98 chances last season – the most of any player in Europe's top five leagues – for free is quite something.

The Turkey international got a goal and an assist on his debut in the 4-0 win over Genoa, prompting coach Simone Inzaghi to proclaim the player "doesn't realise how good he is".

Manuel Locatelli: Sassuolo to Juventus (loan with €25m obligation)

One of Italy's most prized young assets, Locatelli secured a move to Juventus on a two-year loan that includes an obligation to buy for an initial €25m.

Among midfielders in Serie A last season, the 23-year-old made the most touches (3,304), passes (2,749) and tackles (81). He then impressed as Italy won Euro 2020, scoring twice in the group-stage win over Switzerland.

For a club looking to strengthen while saving money, this could prove a shrewd deal for Juve.

Danny Ings: Southampton to Aston Villa (£25m)

Villa appear to have invested the money they received for Grealish in shrewd fashion, signing Leon Bailey, Emiliano Buendia and striker Ings.

While the Ings deal materialised very quickly in early August, he certainly did not seem to need much time to adjust to new surroundings, scoring twice in his first three league games this season.

With 34 goals across his final two league campaigns with Southampton, there is reason to think the 29-year-old could be one of the smartest signings of the window.

Lionel Messi: Free agent to Paris Saint-Germain

The most spectacular free transfer of all time came after Barcelona had agree a new contract with Messi only to be forced to admit they could not let him sign it due to financial restrictions.

A tearful Messi bade farewell to his boyhood club before securing a move to PSG, who now boast a frankly terrifying forward line of Messi, Neymar and Mbappe.

Describing it as a 'free' transfer is somewhat misleading given the various costs involved in the different aspects of the deal, but for PSG to sign arguably the greatest player in history without paying a transfer fee is pretty amazing business.

Romelu Lukaku: Inter to Chelsea (£97.5m)

Chelsea smashed their transfer record to bring back Lukaku, whose last action in his first spell at the club was to miss a penalty in the UEFA Super Cup shoot-out loss to Bayern Munich in 2013.

Lukaku plundered 24 goals and 11 assists in 2020-21 to fire Inter to the title and claim Serie A's MVP award, after which he pushed for a return to Stamford Bridge, where he felt he had unfinished business.

It might have been a serious financial outlay, but Lukaku showed in the 2-0 win at Arsenal what a difference he could make to a Chelsea side who are extremely tough to beat but not exactly free-scoring.

Eduardo Camavinga: Rennes to Real Madrid (€30m)

Madrid may have missed out on top target Mbappe, but they managed to get a deal over the line for fellow Frenchman Camavinga, bringing an end to 18 months of speculation surrounding the young midfielder.

It is the first time Madrid have spent money on a transfer fee since 2019, when they signed Eden Hazard from Chelsea for €100m, and in Camavinga they are signing a player for the here and now rather than the future.

Since making his debut for Rennes in April 2019, no player in Ligue 1 has attempted (230) or won more tackles (139) than the three-cap France international, who will now provide competition for Casemiro, Toni Kroos, Luka Modric and Federico Valverde.

Saul Niguez: Atletico Madrid to Chelsea (loan with option to buy for £30m)

After being regularly linked with the likes of Manchester United and Liverpool in recent years, Saul will finally get a chance to play in the Premier League with Chelsea this season.

A box-to-box midfielder, the Spain international is at his best operating in a central role, though his versatility and workrate have often seen him deployed out wide by Atletico coach Diego Simeone.

He made just 22 league starts last season, his lowest figure since 2014-15. However, since August 2019, Real Madrid's Casemiro (190) is the only midfielder to have attempted more tackles than Saul (159) in LaLiga.

Antoine Griezmann: Barcelona to Atletico Madrid (loan deal with an obligation to buy)

Two years after leaving Atletico in a big-money transfer, Griezmann has returned to the Spanish capital to boost an attack that already includes Luis Suarez, Joao Felix, Angel Correa and fellow new recruit Matheus Cunha.

Griezmann's Camp Nou career never truly took off and he failed to score or create a single opportunity across Barca's first three league games this season.

But Simeone will be confident he can get the Frenchman, who scored 94 LaLiga goals in 180 appearances in his first stint at the club, operating at somewhere close to his former glory.

Cristiano Ronaldo: Juventus to Manchester United (£12.9m rising to £19.7m)

Twelve years after departing Old Trafford, Ronaldo is once again a Manchester United player after completing a surprise return to the club where he won the first of his five Ballons d'Or.

Ronaldo scored 118 goals in 292 appearances under Alex Ferguson in his first spell, 42 of those goals coming in the 2007-08 season alone, and he remains a prolific forward despite his all-round game changing with time.

The Portugal captain scored 29 league goals in his third and final season with Juventus to win the Capocannoniere, making him the first player to finish as top scorer in Serie A, LaLiga and the Premier League.

The first international break of the 2021-22 campaign has arrived, and with it comes an opportunity for many national teams to start afresh.

Following the conclusion of the Copa America, Gold Cup and Euro 2020 in quick succession, all roads now lead to the 2022 Qatar World Cup.

For a number of players, the September qualifiers provide an opportunity to make an impression, while for others it is potentially a first taste of international football. 

With the games coming thick and fast over the next week or so, Stats Perform has looked at those in contention to make their senior international debuts.

Albert Sambi Lokonga (Belgium)

Belgium's golden generation of talent missed another opportunity to turn promise into something more tangible when losing to eventual winners Italy in the Euro 2020 quarter-finals.

Roberto Martinez has decided against wholesale changes after that disappointment, with Lokonga the only outfield player in line for his first cap, having failed to get further than the bench – against Greece in June – after previous call-ups.

A product of the same Anderlecht youth system that oversaw the development of Romelu Lukaku, Youri Tielemans and Leander Dendoncker, among others, Lokonga sealed a move to Arsenal in July after impressing in the Belgian top flight.

The £15million signing has not had the best of starts to life at Arsenal, the Gunners finding themselves bottom of the English top-flight table having played at least three league matches for the first time since October 1974.

Lokonga, noted for his ability to play in front of the defence, featured in just two of those games yet still trails Granit Xhaka alone in terms of passes (113 to 139) and successful passes (97 to 118) and is behind only Sead Kolasinac for interceptions.

Claudinho (Brazil)

Citing concerns over the availability of his European-based contingent due to clubs being reluctant to release players to red-list countries, Tite has named a bloated Brazil squad for this month's triple-header of World Cup qualifiers.

Those complications appear set to deny Raphinha a debut, having impressed during his first year in the Premier League with Leeds United. 

Raphinha ranks seventh in the division for dribbles attempted since the start of last season (142), completing 42.96 per cent of those. He also ranks in the top 10 for chances created over that period with 68.

But Claudinho remains in line to be capped for the first time, called up after helping his country secure Olympic gold at Tokyo 2020.

The midfielder, whose signing at Zenit was announced not long after the Olympic tournament had concluded, described his call-up as "a dream come true".

Theo Hernandez and Moussa Diaby (France)

It is out with the old and in with the new as far as France's first post-Euros squad is concerned – to an extent, at least, with Olivier Giroud one of nine players to make way from the previous group named by Didier Deschamps.

Injuries have also played a part in that, potentially giving a quartet of uncapped players the chance to impress in the upcoming qualifiers with Bosnia-Herzegovina, Ukraine and Finland.

Hernandez, a more natural left-back option than brother Lucas, will feel his first call-up is long overdue following back-to-back campaigns as a regular for Milan, whom he joined from Real Madrid. 

Since making his Rossoneri bow in September 2019, no defender in Serie A has completed more dribbles than Hernandez (133), while only Federico Dimarco (87) and Juan Cuadrado (107) have created more chances than his 86.

Monaco midfielder Aurelien Tchouameni and Roma's Jordan Veretout may also feature during this international break, but perhaps the most exciting of the new additions is Bayer Leverkusen winger Diaby.

The Paris Saint-Germain product scored twice and assisted another in Leverkusen's opening two Bundesliga games of 2021-22, while Alphonso Davies is the only player in the division to have attempted more dribbles this term (24 to his 22).

Known for his blistering pace and ability to take on opponents, Diaby could well provide Deschamps with a different option in an attack already packed full of talent.

Otavio (Portugal)

Three new players have been called up by Fernando Santos, who is looking to the future after his Portugal side's reign as European champions came to an end in July.

Goncalo Inacio is injured, but Diogo Costa and Otavio could each make their senior debuts during this international window, with the latter the name on many lips right now.

Otavio has tallied 11 goal involvementss in each of the past two Primeira Liga campaigns for Porto and has made a fast start to the new season with two assists in his first four games.

Since the start of last season, only team-mate Mehdi Taremi has provided more assists (12) in the Portuguese top flight than Otavio's 10, coming from 51 chances created.

The Brazilian-born attacking midfielder was granted Portuguese citizenship earlier this year and will be eager to show that Brazil's loss is very much Portugal's gain should he get some minutes over the next week.

Ricardo Pepi (United States)

The dual-national drama surrounding Pepi appears to have reached a resolution as the FC Dallas forward has seemingly pledged his allegiance to the United States over Mexico.

After breaking into the Dallas side two years ago and featuring regularly last year, 2021 has been quite the season for the El Paso-born youngster.

Pepi, who does not turn 19 until next January, has 11 goals and two assists in 21 games this term and scored the decisive kick in last week's penalty shoot-out win for MLS against their Liga MX counterparts in the All-Star Game.

He has 13 MLS goals in total, the fourth-most ever by a teenager – ahead of Freddy Adu – and just nine short of the record held by Diego Fagundez.

On the basis of the past four months in particular, the USMNT could have a potentially world-class player to lead their line for a number of years to come.

Karim Adeyemi (Germany)

For the first time in 17 years, Germany will play a match without Joachim Low in their dugout either as assistant or head coach when they face Liechtenstein on Thursday.

Hansi Flick is tasked with ushering in a new generation of German talents, with help from the old guard, many of whom were key to his successful spell at Bayern Munich.

Away from regulars such as Thomas Muller, Leon Goretzka, Joshua Kimmich and Manuel Neuer, Flick has included four uncapped players in his first squad – David Raum, Nico Schlotterbeck, Florian Wirtz and Adeyemi.

A technically gifted and supremely fast winger, Adeyemi has long been considered one of Germany's most promising young players, having cost Salzburg a reported €3m when he was 16.

Adeyemi, who left Bayern six years earlier, has been given the chance to spread his wings with Salzburg and has been strongly linked with Red Bull sister club RB Leipzig.

He already has six goals in six Austrian Bundesliga appearances this term, just one less than he managed in 29 top-flight appearances last time out – a return he will be looking to build on if he is given the nod by Flick.

Justin Bijlow (Netherlands)

The Netherlands are another European heavyweight going through a transitional period of sorts after turning to veteran coach Louis van Gaal for a third stint in charge.

Frank de Boer failed to get the most out of this talented Dutch squad and already Van Gaal has put his own mark on the team by calling up a few newbies.

There will be plenty of focus on the goalkeeping position as, with Jasper Cillessen not fully fit and Maarten Stekelenburg recently retiring, Joel Drommel and Bijlow can stake a claim to be the long-term number one.

Bijlow is considered one of the finest young goalkeepers in Europe and already has 45 Eredivisie games under his belt for Feyenoord, where he is a real fan favourite.

The 23-year-old has kept 15 clean sheets across those appearances and boasts a save percentage of 72.16. Van Gaal can seemingly rely on the young stopper, as he has made just one error leading to a goal.

A whirlwind day last Friday saw Manchester United reach an agreement with Juventus to bring Cristiano Ronaldo back to the club.

The deal was confirmed just hours after it had looked likely the Portugal star would be heading to Premier League champions Manchester City instead.

According to reports, United manager Ole Gunnar Solskjaer encouraged the club to enter the race when it began to seem inevitable Ronaldo would head to the Etihad Stadium. Contact from Bruno Fernandes, Rio Ferdinand and even Alex Ferguson helped persuade Ronaldo that a return to Manchester could mean only one thing.

It all made for a short-lived but extraordinary transfer saga that ended with United re-signing a player who made history with the club between 2003 and 2009, winning three Premier League titles, the Champions League and the first of his five Ballons d'Or.

Here, Stats Perform looks at some other deals that caused a shock in the sporting world...

Lionel Messi: Barcelona to Paris Saint-Germain, 2021

In the most sensational free transfer of all time, PSG again laid down a marker to the football world with the signing of Lionel Messi on a two-year contract. Just as he looked to sign a new Barcelona contract, the club informed him that their dire financial situation meant they could not bring their greatest ever player back under LaLiga's salary restrictions after his previous deal expired in June. A tearful Messi said farewell to the only club he had ever played for before heading to the fanfare of Paris and a reunion with Neymar.

Neymar: Barcelona to Paris Saint-Germain, 2017

The Brazilian had formed a potent attacking trio with Messi and Luis Suarez at Camp Nou but a move to PSG was inevitable when the French side met his world-record buyout clause of €222million. He has played an important role in their continued dominance of French domestic football but has so far been unable to guide them to Champions League glory. He was reduced to tears by his side's 1-0 defeat to Bayern Munich in the 2020 final and then failed to inspire the team in the 2021 semis as Manchester City knocked them out.

LeBron James: Cleveland Cavaliers to Miami Heat, 2010

Basketball icon James announced he would sign with the Miami Heat instead of returning to his hometown team, the Cleveland Cavaliers. Then a two-time NBA Most Valuable Player and a six-time All-Star, James added to the spectacle of the stunning move by announcing it on a special television broadcast called The Decision. He enjoyed four years in Miami, where he won a pair of NBA titles, before returning to the Cavaliers in 2014. 

Tom Brady: New England Patriots to Tampa Bay Buccaneers, 2020

Few people expected Brady to leave the Patriots after 20 years and six Super Bowl victories. Not only did one of the game's greatest ever quarterbacks leave, but he joined one of the least successful franchises in NFL history and instantly guided them to glory, leading the Buccaneers to the franchise's second Lombardi Trophy with a 31-9 triumph over the Kansas City Chiefs in Super Bowl LV.

Luis Figo: Barcelona to Real Madrid, 2000

Should Messi ever return to Camp Nou as an opposition player it is unlikely he will be on the receiving end of the kind of abuse that greeted Figo. Barca fans threw bottles, lighters and even a pig's head at the Portuguese star when he went back to Camp Nou with Los Blancos in the seasons following his controversial move.

Wayne Gretzky: Edmonton Oilers to Los Angeles Kings, 1988

In 1988, the Edmonton Oilers and Los Angeles Kings agreed a deal that shook the NHL to its core. The trade left Canada in disbelief, with a member of the country's parliament even proposing the federal government block the trade or buy Gretzky's contract and sell it to another Canadian team. "The Great One" would go on to enjoy eight successful years in Los Angeles before spells with St. Louis Blues and New York Rangers.

Crack open the bubbly. In France's City of Kings, at the heart of the Champagne region, Lionel Messi made his Paris Saint-Germain entrance as footballing royalty arrived in the 'farmers' league'.

There's a new king in town and although we saw only half an hour of Messi at Reims' Stade Auguste-Delaune, you could hardly take your eye off the man.

Incongruous in the blue of PSG as he was, this is Messi's lot now, the future he has chosen since his Barcelona career ended in a flood of tears.

Ligue 1 gets a rough rap but Messi's arrival instantly makes it box office, and those beholding this spectacle were given a peak into what we should expect.

There was a word in the ear from Mauricio Pochettino and then a hug for Neymar, as Messi replaced the world's most expensive footballer midway through the second half, moments after Kylian Mbappe scored his and PSG's second goal of what turned out to be a 2-0 win.

There was to be no Messi goal, as much as it appeared many inside the stadium were willing there to be one, particularly the pogoing PSG ultras.

His entrance and then his first touch, a simple 10-yard pass deep inside his own half, were cheered loudly, and it was not long before Messi was collecting the ball and charging forward, driving at pace through midfield and darting towards the penalty area.

Such a familiar sight, and here Messi had the luxury of being able to offload to Mbappe on the right. Mbappe, the player Real Madrid desperately want and might yet get before transfer window closes.

Then came notice from the union of Ligue 1 hardmen that Messi would not have it easy in France.

As Mbappe collected the pass, Messi was given the no-nonsense treatment twice by backtracking Reims players as he sought the return ball, Marshall Munetsi practically grabbing the six-time Ballon d'Or winner around the collar in a fruitless effort to halt his progress.

Mbappe could not quite pick the pass, with Messi surrounded, but it was a moment where you wondered what a rich harvest of goals that combination might produce, and whether we might see its potential come to fruition this season.

Munetsi hacked down Messi again later as the game reached stoppage time. Naturally, Messi has seen it all before. It was handshakes all round at the end.

It might be a different shirt, but this was the same old Messi. There was the thrill of one of those delicious give-and-go movements, and referee Francois Letexier played six minutes of stoppage time too. Why not see a little more?

Deep beneath the streets of Reims lie 200 kilometres of cellars and tunnels housing the finest bottles of bubbles, produced in these parts and maturing underground before being dispatched worldwide.

It pays to be patient, the subterranean conditions bringing the best out of the local delicacy before it reaches its fullest flavour. Bring a bottle out too soon and the product will fall short of the exacting standards 

Messi's 65 minutes on the bench allowed him to size up the pace of the French game at close quarters, and then he was ripe to be released. The cork is out of the bottle now though, and the thrill of Messi at provincial stadiums such as this is one fans will drink in for as long as this stop-off lasts.

He was fouled three times in all, a joint team high alongside Neymar, had 26 touches, and made 95.2 per cent of his passes (20 of 21). He won four of his five duels – those within the laws of the game – and no doubt delighted Pochettino and his Qatari paymasters.

PSG brought their imported grandes marques to a city that exports its homegrown fizzy finery, where the cathedral has witnessed 31 coronations, and they won with goals from a young player they might be dispatching to foreign climes within a matter of hours in return for a king's ransom.

Perhaps Mbappe might just fancy a full season of this, though. Will his partnership with Messi really be a one-night stand?

As jarring as watching this all unfold must have felt in Barcelona, as bitter an aftertaste as it must have left, all it lacked for the Parisians was the crowning glory of a Messi goal, and they will soon be flowing.

Novak Djokovic is a strong favourite to become only the third man to complete a calendar Grand Slam and make history at the US Open.

Djokovic has won all three majors this year and can complete a 2021 clean sweep at Flushing Meadows.

The irrepressible world number one would also go beyond Roger Federer and Rafael Nadal – both absent due to injury – with 21 grand slam singles titles if he triumphs in New York.

There will be no elusive record-equalling 24th major singles crown for Serena Williams, who has not recovered from the hamstring injury she suffered at Wimbledon.

With Ash Barty and Naomi Osaka the leading contenders to take the women's singles title, Stats Perform use Opta data to preview the final grand slam of the year.

WHAT A DIFFERENCE A YEAR MAKES FOR DOMINANT DJOKOVIC

Djokovic was thrown out of the US Open last year after accidentally hitting a line judge in the throat with a tennis ball.

The 34-year-old arrived in New York in far better spirits than when he left last September, having taken on all comers this year.

Djokovic missed out on a Golden Slam when he failed to win Olympic gold in Tokyo, but he could join Don Budge (1938) and Rod Laver (1962 and 1969) as the only men to win all four majors in the same year.

Maureen Connolly (1953), Margaret Court (970) and Steffi Graf (1988) are the only women to achieve the incredible feat.

BARTY TO GO BACK-TO-BACK?

Barty became the first Australian woman to win a Wimbledon singles title for 41 years in July.

Not since Williams in 2012 has a player claimed back-to-back women's singles major crowns in the same year, but Barty could take some stopping.

She could become the ninth woman in the Open Era to win Wimbledon and the US Open in the same season. 

Margaret Court, Billie Jean King, Chris Evert, Martina Navratilova, Steffi Graf, Martina Hingis, Venus Williams and Serena Williams can boast that achievement.

OSAKA BACK TO DEFEND TITLE

Japanese sensation Osaka won her third grand slam title at Flushing Meadows last September and went on to add a fourth at the Australian Open this year.

Osaka returns to grand slam action for the first time since withdrawing from the French Open, citing struggles with her mental health.

The world number three could be the first woman to win consecutive titles at Flushing Meadows since Serena Williams claimed three in a row from 2012 to 2014.

Osaka is the only woman to win at least one major title over the past four seasons, winning the Australian Open in 2019 and 2021, as well as the US Open in 2018 and last year.

ZVEREV BIDS TO BANISH PAINFUL MEMORIES

Alexander Zverev was beaten by Dominic Thiem in his maiden grand slam final in New York last year after the German had been two sets up.

He will not have to face Thiem this time around as the defending champion is sidelined due to injury.

Zverev was the only player to serve 100 or more aces during the tournament last year, firing down 131 but also racking up more double faults (64) than anyone else.

The world number four won his fourth title of the year in Cincinnati last week but Djokovic is undoubtedly the man to beat at Flushing Meadows.

Novak Djokovic has history in his sights as he begins his US Open quest; after three grand slam titles in 2021, a fourth beckons at Flushing Meadows.

Rod Laver was the last man to achieve a sweep of the Australian Open, French Open, Wimbledon and US Open singles in the same year, all the way back in 1969.

Steffi Graf won all four on the women's side in 1988, and it seemed a knock-in that Serena Williams would do likewise in 2015 when she headed to the US Open with three majors already bagged.

But winning any title at that level is never easy, and Williams famously came unstuck when she faced Roberta Vinci in the semi-finals.

Djokovic will be mindful that what seems an inevitability to the outside world remains very much still only a possibility. After his US Open tribulations last year, and a recent jolt at the Olympics, he will know anything can happen.

Here, Stats Perform looks at how Djokovic's situation at Flushing Meadows carries most of the hallmarks of Serena's own position as she headed into the tournament six years ago.

IT'S ALL ABOUT THE SLAMS

It was not always this way, but Djokovic has reached the point in his career when he can choose targets, decide which records he wants to break, and throw everything at those goals.

At the start of the year in Australia, he savoured triumphing at Melbourne Park for a ninth time and pointed to how Roger Federer, Rafael Nadal, Williams and Margaret Court had achieved so much.

"They've made history already," Djokovic said. "They made a tremendous mark in our sport. I'm trying to build that and develop that myself in a very unique, authentic way that is suitable to me.

"Whether I think about winning more slams and breaking records, of course. Of course, I do. And most of my attention and my energy from this day forward, until I retire from tennis, is going to be directed in majors, trying to win more major trophies."

It had very clear echoes of Williams in 2015, also in Australia, setting out her own ambitions for the year and specifically targeting the French Open and Wimbledon.

"Those are the two I really have my eye on, because I would like to do better at those. And I know I can do better," she said.

Williams set her heart and mind on that twin challenge and won both.

"I definitely am not going to play as much this year, and I'm just going to go for everything when I do play," said Williams.

BUILDING UP

When Williams reached New York in August 2015, she had delivered a 48-2 win-loss record for the season, landing each of the majors alongside the Miami Open and the Western and Southern Open. Petra Kvitova in Madrid and Belinda Bencic in Toronto had been the only two players to get the better of the 33-year-old Williams.

Djokovic has a 38-5 record for the year, albeit it has the feel of a more dominant year for the 34-year-old Serbian. Two of those losses came at the Olympics, in a semi-final and bronze medal match, and the other three came in his first three events on clay, losing to Dan Evans in Monte Carlo, Aslan Karatsev in Belgrade and Nadal in Rome.

When it mattered on clay, though, Djokovic majorly turned up in Paris, gutsily beating Lorenzo Musetti from two sets down in the fourth round, ending Nadal's streak of four Roland Garros titles by sinking the Spaniard in the semi-finals, and then leaving Stefanos Tsitsipas devastated in the final, with another fightback after dropping the first two sets.

Wimbledon followed, and Djokovic by then was openly targeting a Golden Slam – each major and the Olympic title.

Much like with Williams and her loss to Bencic in the Toronto semi-finals six years ago, however, Djokovic showed he was fallible as history beckoned. From a set up, he lost to Alexander Zverev at Tokyo 2020, a blow that was compounded by missing out on bronze when Pablo Carreno Busta sprang another shock.

HISTORY CAN BE A FIERCE OPPONENT

Williams and Djokovic have won non-calendar Grand Slams before, winning four in succession spanning two seasons.

Williams first achieved that from the French Open in 2002 to the Australian Open in 2003, and in 2015 she was aiming for five slams in a row at the US Open, having begun her dominant streak at her home grand slam the previous year.

She won the first set of the semi-final against Vinci, the world number 43, but was then second best to the Italian, with Williams saying her conqueror "played literally out of her mind".

But the disappointment was stark, underlined by Williams' terse response to the question of how disappointed she felt by the result.

"I don't want to talk about how disappointing it is for me," she said. "If you have any other questions, I'm open for that."

The four-in-a-row feat has only been performed once by Djokovic, from Wimbledon in 2015 to the French Open in 2016. Had he not been disqualified during the US Open last year for carelessly hitting a ball that struck a line judge, he would most likely currently be on a four-slam streak.

Those who win the first three slams of the year often do complete the set, but there are four instances of singles players falling one short by failing in the year's last major.

Before Williams, the most recent case was Martina Navratilova in 1984, when the imperious left-hander headed to the Australian Open – then played at the end of the year rather than the start – in pursuit of the Grand Slam. She lost to Helena Sukova in the semi-finals, and said: "If I'd have won, I'd have done it all. If I lost I had to start from scratch. Both are hard to cope with."

Navratilova had won 74 consecutive matches until that loss and ended the season with a 78-2 record.

In the men's game, Jack Crawford (1933) and Lew Hoad (1956) also fell short, both losing in finals of the US National Championships, the tournament that became the US Open. Don Budge (1938) and Laver (1962 and 1969) are the only men to have won a calendar Grand Slam in singles.

The weight of expectation is immense for Djokovic as he pursues what would be his crowning glory, not only sealing the Grand Slam but reaching 21 majors, one ahead of Nadal and Federer and into the outright lead in the men's game. The prospect cannot be ignored, and it will be a heavy burden to carry over the coming fortnight.

As Djokovic said on Friday: "I would be lying if I said that’s not something that I’m thinking about or that my attention is not going that way.

"I’m very motivated to play my best tennis. But I have to hit one ball at a time, as they say, try to be in the moment, have a guiding star in a way, a dream to win a slam here."

Cristiano Ronaldo is set to be playing back at Old Trafford again in 2021-22 after Manchester United confirmed they have reached an agreement with Juventus for the transfer of the Portugal great.

While personal terms, a medical and visa are still to be sorted out for Ronaldo, it would take something remarkable to stop him from joining now after a deal reportedly worth up to €23million (£19.7m) was agreed with Juve on Friday.

For a short while it looked as though Ronaldo – who had asked to leave the Bianconeri – was heading to Manchester City after they missed out on the signing of Harry Kane.

But apparent interventions from Ronaldo's former United manager Alex Ferguson and old team-mate Rio Ferdinand may have swung the race in the Red Devils' favour.

Ole Gunnar Solskjaer seemed to open the door to Ronaldo during his news conference on Friday, and just a few hours later United confirmed a deal had been struck with Juventus.

Following confirmation of the deal, Stats Perform takes a look at greats who went back to their spiritual home, starting with the Portugal captain…

Cristiano Ronaldo – Manchester United

Ronaldo spent six years at Old Trafford during his last spell, arriving as a lanky teenager who probably averaged four stepovers per minute before leaving as a Ballon d'Or winner and an ice-cold finisher. His then-world record move to Real Madrid had been a long time coming and he spent nine years at the Santiago Bernabeu, becoming the club's all-time top scorer as he continued his transition from winger to out-and-out 'number nine'. There he won four Champions League titles before moving on to Juve, for whom he plundered 81 goals in 98 Serie A matches and picked up two Scudetti. But now he is all set for a return to England – whether he can match the standards he set last time remains to be seen, with his 31-goal haul of 2007-08 only bettered once in a 38-match season, though United fans will be convinced he can fire them to a first league title since Ferguson left.

Arjen Robben – Groningen

Robben's first retirement lasted just a single season, having announced last year he would be returning to his boyhood club Groningen for the 2020-21 campaign. Robben, now 37, initially brought an illustrious playing career to an end in July 2019 shortly after his 10-year spell with Bayern Munich finished. Although at the time he was linked with a potential return to the team that gave him his professional debut, Robben – who suffered with numerous injury problems throughout his career – opted to retire. He then caused something of a shock as he finally went back to the place where it all began, but once again injuries blighted his availability, restricting him to just seven Eredivisie appearances in 2020-21. Club director Mark-Jan Fledderus wanted him to stay on for another year, but when Robben said at the end of the season that he was going to have a long think about his future, the writing was seemingly on the wall. Another U-turn appears unlikely.

Juan Roman Riquelme – Argentinos Juniors

Perhaps more synonymous with Boca Juniors, where he made his professional debut and also spent most of his final years, Riquelme also had a strong affinity with Argentinos Juniors. He came through the club's academy in the early-to-mid 1990s, before then finishing his immense career at Estadio Diego Maradona in 2014, having also played for Barcelona, Villarreal and Argentina. Although the iconic attacking midfielder appeared close to joining Paraguay's Cerro Porteno the following year, the move never materialised.

Dirk Kuyt – Quick Boys

Kuyt briefly came out of retirement three years ago to help Quick Boys, with whom he spent 13 years as a youth. Playing in the Derde Divisie Saturday league, Kuyt was already working as assistant at the time, but made himself available for selection during a striker shortage and he made three appearances. The former Netherlands and Liverpool forward had retired the year before following a second spell with Feyenoord, where he had made his initial breakthrough in the mid-2000s, his form at the time earning a move to Anfield.

Rafael Marquez – Atlas

One of Mexico's greatest players, Marquez's longevity at such a high level was nothing short of incredible, as he accumulated 147 international caps. After breaking into the Atlas team as a teenager having come through their academy, the elegant centre-back enjoyed a sparkling career in Europe, winning 14 titles across spells with Monaco and Barcelona. Time with New York Red Bulls, Leon and Hellas Verona followed, before a final two-year stint back at the Jalisco ended in 2018. Although plagued by off-field allegations towards the end of his career, Marquez went on to become the club's sporting president, before standing down last in 2019 to focus on other areas of the sport. He was expected to be taking up a youth coaching role at Barca this season, but the deal ultimately fell through.

Henrik Larsson – Hogaborgs

While the Swedish club most may associate with Larsson is Helsingborgs, he actually made the breakthrough at a smaller side – Hogaborgs. It was here where he trained from the age of six, before eventually becoming a regular in the senior side and earning a move away. A trophy laden career followed, taking him to Feyenoord, Celtic, Barcelona and Manchester United. Although he retired in 2009, he returned to the pitch for Raa in the Swedish third tier three years later, before then finding himself back in the team at Hogaborgs in 2013, helping out due to an injury crisis despite him only previously being registered to a casual team for 'seniors'. This gave him the chance to play alongside his son, Jordan.

Carlos Tevez – Boca Juniors

The Tevez-Boca love affair has dominated most of the striker's successful and complex career. After coming through their youth ranks, the feisty forward was seen as the heir to Maradona. A brief stint in Brazil with Corinthians followed, but Europe had long since beckoned, even if West Ham was by no means the expected destination. He went on to play for Man Utd and City, increasing tension between the clubs, before then going to Juventus, but throughout this time Tevez seemed to long for a return to Boca. He went back to La Bombonera in 2015, his homecoming interrupted by a brief spell with Shanghai Shenhua in 2017 in the Chinese Super League, though even Tevez acknowledged he saw his time in China as a "holiday". "He filled Santa's sack with dollars and now he has returned to Boca," was Maradona's assessment upon 'El Apache's' return from the CSL. His third spell with Boca ended in June 2021 and it remains to be seen if he ever plays for another club.

Gianluigi Buffon – Parma

Buffon likes a comeback. Having returned for a second spell at Juventus in 2019, the goalkeeping great departed the club for a second time at the end of 2020-21. The Italy legend suggested he had not finished playing yet and Parma quickly emerged as a potential destination despite their recent relegation to Serie B. After a few weeks of contemplation, it was confirmed that Buffon was heading back to the club where he made his name. Now 43, the iconic stopper is wearing Gialloblu for the first time in 20 years, and he is set to remain with them until he turns 45, given he signed a two-year contract. What happens after that is anyone's guess but calling it a day with his first club could be a satisfyingly romantic conclusion to a remarkable career – that or he ends up at Juve again!

He is back where he belongs.

— Parma Calcio 1913 (@1913parmacalcio) June 17, 2021

The 2021-22 Serie A campaign commences on Saturday following a busy close season that saw more than half of the 20 teams change head coach.

Antonio Conte departed Inter after guiding the club to their first Scudetto in more than a decade, with Simone Inzaghi being plucked from Lazio, who in turn turned to Maurizio Sarri.

Sarri's former club Juventus decided to end the Andrea Pirlo experiment after just a year and opted for a familiar face in six-time title winner Massimiliano Allegri as his replacement.

Luciano Spalletti is back in Serie A with Napoli, meanwhile, and Jose Mourinho has returned to Italy with Roma some 11 years on from his hugely successful stint with Inter.

There will be just as much focus on the dugouts as the field when the new season gets up and running this weekend, then, and some coaches are facing a tougher challenge than others.

Stats Perform looks at what the managerial changes could mean for some of Serie A's biggest clubs.

Inter 

In: Simone Inzaghi

Out: Antonio Conte

Conte will go down in Inter folklore as the man who ended the club's 11-year wait to return to the top of Italian football.

In an ideal world, one in which the Nerazzurri were not in a position whereby they had to sell star players to balance the books, Conte would still be in charge at San Siro.

As it is, though, Inzaghi will be at the helm this coming season and is in a rather unenviable position of having to pick up where Conte left off, minus the goals of Romelu Lukaku.

Inzaghi has his own vision but does not differ too much from Conte in terms of tactics, both coaches favouring a 3-5-2 formation of sorts throughout their careers.

Moving the ball forward quickly will be the aim, with Milan (90) the only side in Serie A last term to register more direct attacks than Inzaghi's former side Lazio (89). By comparison, Inter were third on that list with 80.

While the structure will remain largely the same, losing Lukaku and influential wing-back Achraf Hakimi – albeit with Edin Dzeko and Denzel Dumfries arriving – means Inzaghi will need to get more out of others if Inter are to retain their crown.

Lazio

In: Maurizio Sarri

Out: Simone Inzaghi

The man tasked with replacing Inzaghi at Lazio is Sarri, who endured mixed fortunes during his most recent two stints in Serie A with Napoli and Juventus.

Having come so close to ending Juve's stranglehold on the title in 2017-18 while at Napoli, the 62-year-old won the Europa League in his solitary season at Chelsea and was then given just 14 months at the Allianz Stadium.

His stint in Turin came to an early end despite leading Juve to top spot, his style of play – coined 'Sarriball' – deemed too distant from what Juventus typically expect from a head coach (more on that later!).

At the Stadio Olimpico, Sarri will have more freedom to put his spin on things as he looks to build or improve upon last season's sixth-placed finish. A back four, rather than the three-man defence Inzaghi favoured, can be expected.

Sarri teams are known for their verticality, meaning they like to move the ball forwards. Lazio, as already touched upon, are a good fit in that regard.

They ranked lowest in the top eight last season for build-up attacks (83), which is defined as the number of open play sequences that contain 10 or more passes and either ends in a shot or has at least one touch in the opposition box.

The big question, though, is whether Sarri has the personnel to turn Lazio into top-four regulars in the same way he did at Napoli. With Immobile taking on the Gonzalo Higuain role up top, it might just be a possibility.

Juventus

In: Massimiliano Allegri

Out: Andrea Pirlo

While a lot of clubs mentioned are entering the unknown with their managerial appointments, Juve know exactly what they are getting in Allegri.

The 54-year-old guided Juve to five straight Serie A titles and two Champions League finals between 2014 and 2019, having also previously lifted the Scudetto at Milan.

Only one coach in the Bianconeri's history, Giovanni Trapattoni, has overseen more league games than Allegri's 190, while Juve's two highest-scoring seasons dating back as far as 1930 have both come under the stewardship of the returning favourite.

This Juve side has changed since Allegri's first stint, though, and it may take him time to make this team his own again following the aforementioned reigns of Sarri and Pirlo.

Whereas Sarri and Pirlo were a little complex with their tactics and what they expected from players, Allegri will take a different approach. That is not to say Juve will not be able to chop and change things under Allegri, as they did in his previous spell.

One aspect that will surely differ from last season is the number of goals Juve score. They found the net an underwhelming 56 times from open play last season from an expected goals return (xG) of 54.3.

By comparison, champions Inter scored 65 open play goals from a near identical xG as Juve of 54.6. With the prolific Cristiano Ronaldo set to stay at the club for at least one more season, there is hope of reclaiming the title this time around.

Roma

In: Jose Mourinho

Out: Paulo Fonseca

The highest-profile of the incoming coaches in Serie A this season, Mourinho arrives with his 'Special One' status still intact in Italy thanks to his success at Inter a little over a decade ago.

Mourinho won as many league titles in two seasons at San Siro (two) as he has in the 11 years since (one), while also lifting the second of his Champions League crowns, the Coppa Italia and Supercoppa Italiana during that trophy-laden stay.

The Portuguese won 62 per cent of his matches at Inter but that win rate has steadily declined and he won just 51.2 per cent of his games with Tottenham, leaving the club in April after just 17 months in charge.

Mourinho's sides were so often hard to beat, but Spurs lost 13 times in 2020-21 under him, making it his worst ever season in that regard and he did not even see it all the way through.

But could his career take a turn in the right direction in Rome? Mourinho's tactics have remained largely consistent throughout his career, no matter the club or country he is coaching in.

The back three largely favoured by Paulo Fonseca will become a back four and there will be particular emphasis on Bryan Cristante, a typical Mourinho player in many ways, to shield the defence and get the ball forward.

The addition of Tammy Abraham from Chelsea is clearly a Mourinho signing, helping the fill the void left by Edin Dzeko, but Mou's pragmatic approach is surely a concern for a Roma side that looked better offensively than defensively last season. 

Finding the correct balance will be key, and that ultimately depends on whether Roma have hired the pre-2015 Mourinho or post.

Napoli

In: Luciano Spalletti

Out: Gennaro Gattuso

With spells at seven different Italian clubs under his belt, including two years at Inter, Spalletti certainly does not lack of experience. After two years out of the game, however, the 62-year-old has to quickly prove he is not yesterday's man.

Spalletti made clear when he took over from Gennaro Gattuso that he will look to operate with a 4-3-3, though on the basis of pre-season it may well be a more familiar 4-2-3-1 come the opening day.

He inherits a talented squad that includes the likes of Piotr Zielinski, Victor Osimhen, Dries Mertens, Hirving Lozano and Lorenzo Insigne – for now – in attack.

Napoli had no problems scoring goals last time out, with no team managing more shots from open play than their 493 and only Atalanta (77) and Inter (65) scoring more from non-set-piece situations than their 64.

Pressing is a big part of Spalletti's game and that makes Napoli a good fit as they ranked joint-second in Serie A last season for goals scored from high turnovers (nine), behind only Atalanta (10).

There are already a few rumblings of discontent behind the scenes with regards to transfer activity, but a kind fixture list ensures that Spalletti can hit the ground running in his quest to guide Napoli back into the Champions League.

Barely a month has passed since Giorgio Chiellini lifted the European Championship trophy at Wembley, and it would seem logical to expect Serie A to begin amid high fanfare.

This may prove to be the case, as the opening weekend of the season arrives, but a major talent drain from the Italian league since last term cannot be ignored.

Romelu Lukaku, Cristian Romero and Gianluigi Donnarumma have all moved on, swapping Inter, Atalanta and Milan respectively for Chelsea, Tottenham and Paris Saint-Germain.

To put those losses into greater context, of the 2020-21 Serie A end-of-season award winners, that is the MVP, the top defender and the leading goalkeeper all exiting the league.

Sweeping changes on the coaching benches also add to uncertainty as the new campaign begins, with a much-changed Inter hoping to successfully defend their title.

JUVE ON A SCUDETTO MISSION

After the folly of handing dugout rookie Andrea Pirlo the reins before last season, Juventus look to be on firmer ground this time with Massimiliano Allegri back as head coach.

They have brought in Manuel Locatelli from Sassuolo, primed to play a Pirlo-like role on the pitch, and it seems Cristiano Ronaldo will hang around for the final year of his contract.

Rumours continue to encircle the five-time Ballon d'Or winner, but Allegri can likely count on his reliable flow of goals, just as he did for the 2018-19 season – Ronaldo's debut campaign in Turin and the end of the line for Allegri in his first stint as coach.

A six-time Scudetto winner, Allegri will look to get the best out of wingers Dejan Kulusevski and Federico Chiesa as they enter their second seasons with the Bianconeri, while it remains to be seen how Paulo Dybala performs as he enters the final year of his deal.

Plagued by injury last season, Dybala started just 14 Serie A games, but results were often perkier when he played. Of those 14 games, Juventus won 10, drew three and lost one, with a points-per-game average of 2.4 when he played from the off, compared to 1.9 when he was absent or a substitute. The win percentage of 71.4 per cent when Dybala was in the starting XI (compared to 54.2 per cent when he was not) is in the ball park that Allegri will be eyeing.

INZAGHI STEPS INTO CONTE SHOES

Social media tells us Antonio Conte has been thoroughly enjoying his summer, topping up his tan and seemingly showing no regret over his Inter exit, which came in May, just weeks after he guided the Nerazzurri to title glory.

Conte reportedly left amid concern the club planned to raise funds with sales that have duly come to fruition. The loss of striker Lukaku feels like a body blow, given his influence, and persistent rumours suggest Lautaro Martinez could also move on. Achraf Hakimi is another big loss, but, as with Lukaku, a big fee was banked as the right-back proved a one-season wonder in Italy.

In have come coach Simone Inzaghi, who impressed at Lazio, while Edin Dzeko will be a straight swap for Lukaku in the forward line, albeit unlikely to carry quite the same threat. Former PSV star Denzel Dumfries can replace Hakimi in the attacking right full-back role, and Inter will hope his Euro 2020 form transfers to Serie A duty.

It is hard to see Inter repeating last season's success, and the comedown could be painful. They exceeded their expected goals total last season, scoring 84 goals against an xG of 75.3, and Inzaghi will look for more of the same.

They possess plenty of quality still, but they have likely lost Christian Eriksen for the long term too after his cardiac arrest on Denmark duty at Euro 2020. His survival was everything in June, and now his recovery is all-important. The knock-on effect is that Inter have lost a player who became important over the second half of the season.

So much has changed since that title was secured. Landing Hakan Calhanoglu on a free from Milan looks like great business, but consolidation with a top-four finish may be their limit in the new campaign. That, and being sure to secure city bragging rights again.

MOURINHO'S BACK AMID MERRY-GO-ROUND

Never mind Inzaghi and Allegri at Inter and Juve, now is the time to get used to the sound of Maurizio Sarri's Lazio, Vincenzo Italiano's Fiorentina, Luciano Spalletti's Napoli ... and Jose Mourinho's Roma. Milan rather feel like the odd ones out, keeping faith with Stefano Pioli.

A whirlwind of change has swept through Serie A, and it will be worth watching to see quite what impact Mourinho can have on a side who finished 16 points short of the Champions League places last term.

His 'Special One' reputation was enhanced the last time he coached in Italy, guiding Inter to a treble of Serie A, Coppa Italia and Champions League in the 2009-10 campaign.

Spells at Real Madrid, Manchester United, Chelsea and Tottenham have followed, but Mourinho's cachet has diminished over the past decade.

Tammy Abraham has followed him in swapping London for Rome, with the Chelsea striker arriving, along with Eldor Shomurodov from Genoa, to pep up an attack depleted by the loss of Dzeko. Rui Patricio has joined fellow Portuguese Mourinho, and the goalkeeper's arrival from Wolves could prove a fine signing.

Roma won just five Serie A away games last term, and have only had fewer once in a season beginning in the 20th century (4 in 2002-03), while their shot conversion rate of 41.35 per cent can be improved upon, given they topped 50 per cent twice in the 2010s.

Most important for Mourinho, perhaps, will be to build on Roma's poor duel success rate (48.97 per cent) and cutting out the errors leading to goals (10 in 2020-21 in Serie A).

The duel figures are important and were the worst Roma had managed in at least 15 years, while the error count will be simply intolerable to the new boss. Only Bologna committed so many costly errors (also 10). Mourinho has his work cut out.

The wait is over. A week-and-a-half after joining Paris Saint-Germain, Lionel Messi could be set to make his debut against Brest on Friday.

Following his shock exit from Barcelona as a free agent, Messi became the Ligue 1 giants' fifth major signing of the transfer window, joining the superstars Mauricio Pochettino already had at his disposal.

Messi, alongside his former Barca star Neymar, has been training this week, and though Pochettino refused to confirm his squad during Thursday's news conference, it is expected the duo will play a part.

With Kylian Mbappe already back, here's how Pochettino could set out at Brest.

GK: Keylor Navas

Navas has been one of Europe's outstanding goalkeepers in recent seasons, ranking third for goals prevented (8.1, using expected goals on target data) in the top five leagues in 2020-21. Gianluigi Donnarumma – the Player of the Tournament at Euro 2020 – did not leave boyhood club Milan just to sit on the bench and, at 22, represents the long-term option, but after only just returning to training, it is likely Pochettino will stick with the former Real Madrid goalkeeper for Friday's game, though the ex-Spurs boss did suggest Donnarumma may be available. 

RB: Achraf Hakimi

Alessandro Florenzi headed back to Roma at the end of his loan, but PSG identified just about the best replacement on the market. Over the previous two seasons, Robin Gosens (34) was the only defender with more goal involvements than Hakimi (30), who scored on his first Ligue 1 appearance.

CB: Marquinhos

PSG won 72.5 per cent of the games Marquinhos played last season in all competitions, conceding 0.7 goals on average. Those numbers altered significantly in his absence, with a winning percentage of 52.9 while shipping 1.1 goals per game. Even with the club's superstar signings, their captain remains one of the key men. Even though he has just returned from an extended break following Brazil's Copa America exploits, it would not be surprising to see the former Roma man thrown straight back into the fray given PSG have conceded three times across their opening two matches.

CB: Presnel Kimpembe

Sergio Ramos, another freebie, may no longer be able to play every game – he appeared only 15 times in LaLiga for Real Madrid last term – but PSG better hope he is there for the big ones. However, the 36-year-old will not be available until September, meaning France defender Kimpembe is likely to continue in the heart of defence for now. He made a game-high four clearances in last week's 4-2 home win over Strasbourg.

LB: Abdou Diallo

This is perhaps the one position on the pitch where PSG lack a genuine world-class option. Even if Pochettino were to bring in Kimpembe as a third centre-back, there is no outstanding left-sided wing-back. Diallo, a defensive full-back in an attacking team, gets the nod by virtue of starting the season fit and ahead of Layvin Kurzawa in the pecking order, while he also assisted Mauro Icardi's opener against Strasbourg.

CM: Ander Herrera

At the end of a season in which Marco Verratti was restricted to only 16 Ligue 1 starts, Euro 2020 provided a reminder of his talents. The Italy midfielder created a tournament-leading 14 chances across just five games while still completing 93.1 per cent of his 417 passes. However, it seems likely we will have to wait to see the playmaker link up with Messi, as he too is only just easing his way back into training. In his place, Herrera seems set to carry on in midfield and, in truth, is a more than able back-up. He attempted 100 passes on matchday two, completing 94 of them.

CM: Danilo Pereira

Leandro Paredes, Messi's international colleague, was trusted for the big occasions in the Champions League. However, he has just returned to training after helping Argentina win the Copa America, while Idrissa Gueye has been out due to COVID-19 protocols. Youngster Eric Ebimbe started against Strasbourg but was replaced by Pereira after an hour, and the towering Portuguese would add some presence in the middle of the park.

CM: Georginio Wijnaldum

Angel Di Maria would be very unfortunate to miss out on a full-strength XI and undoubtedly still has a part to play even with Messi in place, but he too is only just back from international duty. Wijnaldum has featured in both of PSG's Ligue 1 games so far and across his Liverpool Premier League career, led all Reds midfielders in recoveries (951) and duels won (645) and ranked second in interceptions (115) and third in tackles (181).

RW: Lionel Messi

Of course, Messi can play across the front three, but starting from the right – with Hakimi in the Dani Alves role outside him – will bring back memories of Barca teams of old. It is the role he occupied in 2014-15, forming part of perhaps the Blaugrana's most exciting attacking trio, which of course Neymar was also part of.

CF: Kylian Mbappe

Mbappe has the Luis Suarez role, providing the direct runs in behind that create space in front of the defence for Messi and Co, and a video of the two stars linking up in training went viral this week. Last season's 53 goal involvements did not quite match the forward's career-high of 54 in 2018-19, but Mbappe can expect to break all sorts of records in this thrillingly creative line-up this term. He already has two Ligue 1 assists to his name this season, and that is without playing alongside two of the world's best players.

LW: Neymar

Still the world's most expensive player if no longer the biggest name in his own dressing room, Neymar was the third member of that 2014-15 front three. Having decided to step out of Messi's shadow, the Brazil superstar wanted his old friend back. During their four years together at Barca, Neymar assisted Messi 22 times, while the six-time Ballon d'Or winner returned the favour on 20 occasions, and surely the chance to have this sensational front three starting together will be too tempting for Pochettino to turn down – even if it is harsh on the in-form Icardi.

It has been another off-season of change in Italy, but Serie A returns this week and another intriguing campaign awaits.

Inter were champions last term, ending Juventus' run of nine straight Scudetti, but they have not been able to keep their title-winning side together.

Romelu Lukaku is gone, as is coach Antonio Conte, while Massimiliano Allegri has returned to Juve to tee up another tilt.

So, what does that all mean for the coming season? Stats Perform attempts to find out.

The Stats Perform League Prediction Model, created by Stats Perform AI using Opta data, has analysed the division ahead of the new season to assign percentages to potential outcomes for each club.

The model estimates the probability of each match outcome (win, draw or loss) based on teams' attacking and defensive qualities, which considers four years' worth of results, with weighting based on recency and the quality of opposition. The season is then simulated 10,000 times to calculate the likelihood of each outcome.

Read on to see who can realistically compete with Inter and who should be looking over their shoulders...

THREE FIGHTING FOR TITLE

Inter might have lost some key men, but the model is backing a team that finished second and then first to lead the way again.

The Nerazzurri are given the best chance of taking the title (45.1 per cent), while they certainly should make the top four even without Lukaku and Conte, rated as a 94.2 per cent likelihood.

Unsurprisingly, Juve are the closest challengers to Inter's crown, with a 21.5 per cent shot.

It is not set to be a two-horse race, though, as Atalanta are the third and final team to be given a substantial chance at 19.6 per cent.

In fact, Atalanta's lowest probable finish of ninth is higher than Juve's 10th, with another exciting season expected for La Dea.

TOP FOUR SETTLED?

There is strength in depth in Serie A this season, but the model has identified a clear frontrunner for the fourth Champions League place.

Napoli, with a 9.4 per cent title chance, have a 68.6 per cent likelihood of making the top four, putting them well clear of the rest despite finishing fifth in 2020-21.

That means disappointment for big names like Milan, Lazio and Jose Mourinho's Roma.

Milan do have a 44.0 per cent shot at Champions League qualification, but that is a modest opportunity given they were second last term and led the league for half the season. A Scudetto triumph is rated at 3.6 per cent.

Lazio, under Maurizio Sarri, have a 14.9 per cent hope of a top-four place, while Mourinho clearly has work to do as rivals Roma are only given an 8.2 per cent likelihood.

Besides those sides, only Sassuolo – 1.1 per cent for the Champions League, 2.6 for the Europa League and 8.2 per cent for the Europa Conference League – are realistically also in the European picture.

STRAIGHT BACK DOWN AGAIN

The model does not make for pretty reading for the three promoted sides, who are all expected to spend only a single season in the top flight before returning to Serie B.

For Salernitana and Venezia, a particularly brutal campaign could be in store. They are highly likely to go down, rated at 95.9 per cent and 94.8 per cent respectively.

Empoli are given a slightly improved chance but are still expected to be relegated, at 79.3 per cent.

Torino's awful season, finishing 17th in 2020-21, should not be repeated, with merely a 4.3 per cent likelihood of demotion.

That still makes them sixth favourites for the drop, also behind Spezia (6.0 per cent) and Hellas Verona (5.4 per cent).

This should have been a season for Inter fans to enjoy, on the back of a title triumph and with European football returning to some semblance of normality.

Instead, they have lost coach Antonio Conte, top scorer Romelu Lukaku and standout wing-back Achraf Hakimi. Talk of a Tottenham move for Lautaro Martinez – seemingly linked to Harry Kane's future – has not been ruled out entirely.

It leaves the reigning Serie A champions picking up the pieces, with the club's dire financial situation dampening hopes of a successful title defence.

Although there have also been new arrivals, Simone Inzaghi and a 35-year-old Edin Dzeko clearly are not in the same class as Conte and Lukaku.

Inter will be slightly different this season and it is highly likely they will be slightly worse for it.

Downgrade to Dzeko

In Lukaku, Inter have sold a player in his prime coming off his best campaign to date. In Dzeko, the Nerazzurri have brought in a veteran whose Serie A career just plunged to new depths.

Lukaku netted 24 times en route to Inter's Scudetto, while Dzeko's final year with Roma brought only seven league goals.

The Bosnia-Herzegovina international did play a mere 1,825 minutes, but it was his poor form while on the pitch that saw him limited to 20 starts despite featuring in 31 matchday squads.

Dzeko's shot conversion rate of 10 per cent was higher than in two of his seasons in the capital and only margainally lower than 2017-18's 10.5 per cent when he scored 16 times. The decreasing frequency of his attempts was an issue, managing just 3.5 shots per 90 minutes, a trough to contrast to the 2016-17 peak of 5.3.

Inter's new forward fell some way short of his expected goals (xG) total of 13.3 – a failing only partially explained by the expertise of opposition goalkeepers, who prevented 3.6 Dzeko goals according to expected goals on target (xGOT) data, which analyses the quality of the shot rather than the quality of the chance.

Lukaku, on the other hand, outstripped his xG figure of 23.8, even if his attempts were only worth 22.9 xGOT.

It is not only as a scorer that Dzeko slips below Lukaku's standards either. Chelsea's latest record buy was a creative force last term, providing 11 assists. Dzeko had three.

Indeed, Lukaku crafted a team-high 52 chances – or 9.4 per cent of Inter's 552 shots across the campaign – while Dzeko laid on 29 (5.3 per cent of Roma's attempts). Dzeko was more involved in build-up play than Lukaku, averaging 49.7 open play sequences per 90 to his predecessor's 44.4, but he could not match Lukaku in terms of passing accuracy (68.8 per cent), passing accuracy in the opposition half (64.8) or passing accuracy in the final third (58.5).

Unsurprisingly, the former Giallorossi favourite also cannot play at the same pace as Lukaku. Dzeko was involved in only six fast breaks to Lukaku's league-leading 17, although he did score twice from such situations. Roma were second in the league in this regard – behind Inter.

But even if the Nerazzurri do slow slightly with Dzeko in the side, his work in moving the ball up the field is still comparable to Lukaku's. He had more carries (7.9) and progressive carries (4.5) than Lukaku last term, while operating in the same ballpark for carry distance (92.6 metres), attempted dribbles (2.9) and completed dribbles (1.3) – all numbers per 90.

The percentage of his touches Dzeko took in the opposition box (17.3) tallied closely (18.3 per cent for Lukaku), too, with the previously prolific attacker's game peculiarly now suited to work away from goal.

An aerial force

As part of his link-up play, Dzeko offers a clear focal point. His 60.4 per cent success rate in aerial duels ranked fourth among Serie A forwards with 100 or more such tussles. Lukaku won only 42.9 per cent in a category led by Zlatan Ibrahimovic (65.7 per cent). Dzeko's 52 flick-ons also put him fourth.

But Dzeko's heading ability does also give Inter a greater threat inside the penalty area. The striker was joint-third for headed attempts (20, excluding blocks), with his 1.0 per 90 double Lukaku's 0.5. As with his feet, Dzeko was wasteful in this regard, scoring only one header while new Inter colleague Martinez nodded in four goals, but a greater sample size shows the danger he can pose. Since his 2015 Serie A debut, Dzeko leads the way for headed attempts (203, excluding blocks) and his 16 goals – making up 18.8 per cent of his total of 85 – are tied for third.

Dzeko therefore looks a good fit in an Inter side who last season topped the charts in succeeding with 24.6 per cent of their open play crosses, leading to a joint-high 92 headed shots and 14 headed goals.

Whether that crossing quality is still at the club is another matter.

Inter's wings clipped

Only nine defenders in Serie A last term attempted 100 crosses, but Hakimi, marauding up the right, was one of them. Within that select group, his crossing accuracy of 23.9 per cent ranked third – just ahead of Leonardo Spinazzola, another exciting wing-back and Dzeko's former Roma team-mate (23.5 per cent).

Hakimi's departure for Paris Saint-Germain robs Inter of that quality and the 36 chances he created. There is pressure on Denzel Dumfries, a €12.5million recruit, to fill that void. He created 41 chances in the Eredivisie last season, yet only five of his 50 crosses were successful.

That ability to deliver from wide positions is merely one of Hakimi's array of attributes, too, with the €60m man carrying the ball 22.7 metres further per 90 than Dumfries while also contributing a goal or assist every 178.1 minutes, compared to the Netherlands international's 308.5 minutes.

Inter should at least have increased creativity from midfield, where free signing Hakan Calhanoglu offers an upgrade on the recuperating Christian Eriksen. Calhanoglu, playing for rivals Milan, had league highs in chances created (98) and chances created from set-pieces (50) in 2020-21. Milan led Serie A in goals from set-pieces (16, excluding penalties), but Inter ranked joint-fourth (16) and will surely now improve.

Trying to run it back

If mixed results are anticipated from direct replacements for Lukaku, Hakimi and Eriksen, those moves at least indicate some unlikely joined-up thinking in spite of the chaotic nature of this off-season. Inzaghi's appointment also suggests Inter plan to change little from last season, even with the numerous notable departures.

Like Conte and Inter, Inzaghi's Lazio consistently lined up with a 3-5-2 formation in 2020-21, with their approaches also not dissimilar.

Lazio's press was a little more aggressive, allowing 11.6 passes per defensive action to Inter's 12.8 and also engaging in more pressed sequences (543) despite having slightly more possession (52.9 per cent) than Inter (52.0 per cent). Lazio also scored eight goals from high turnovers.

However, between the replacement of a speedy Lukaku with a slower Dzeko and Inter's pre-existing preference for build-up attacks (119) over direct attacks (80), Inzaghi's playing style might have to be a little more patient this term, even if the new number nine's physical presence will give them an outlet.

These are minor tweaks, though, that should mean Inzaghi can adapt to Inter or Inter to Inzaghi.

Defending champions have rarely had it so tough when preparing for a new campaign, but Inter have done all they can to ensure a new-look side can continue to find success.

Bayern Munich were not the biggest club in their own city, let alone the country, when Gerd Muller signed in 1964.

The Bavarians' major trophy haul at that time consisted of a single league championship in 1932 and a maiden DFB-Pokal success 25 years later. Muller joined a second-tier side.

On Tuesday, two days after the club great's passing, Bayern celebrated his life in fitting fashion with a record-extending ninth DFL-Supercup triumph – a competition they have to win silverware simply to enter.

The Bundesliga dominance, cup after cup and six European crowns... all that history can be traced back to Muller's decision to head for Bayern rather than rivals 1860 Munich.

He was there for the first four Bundesliga titles – the top scorer on each occasion – and for three European Cups in three years, Muller's standards slipping as Jupp Heynckes was the leading marksman in the third season.

In 15 years, the remarkable forward tallied 566 Bayern goals, a benchmark that stands to this day. Muller's Bundesliga total of 365 is also unsurpassed.

As those numbers show, breaking a Muller record is no simple task, but Robert Lewandowski finally did so last season when scoring 41 goals in a single Bundesliga campaign, edging beyond the legend's 40 in 1971-72.

"I achieved a goal that once seemed impossible to imagine," Lewandowski wrote on his Twitter page in May. "I'm so unbelievably proud to make history for Bayern, and to play a part in creating the stories that fans will tell their children – following in the footsteps of legends like Gerd Muller."

It made sense then for Lewandowski to be front and centre again at Signal Iduna Park as Muller was remembered.

He clutched a number nine shirt ahead of kick-off as a moment's silence broke into applause, the Borussia Dortmund fans recognising a legacy that goes beyond club lines.

It was a lovely tribute, but Muller would have been more familiar with Lewandowski's subsequent nods to his greatest predecessor.

Muller was the ultimate 18-yard box centre-forward, a mantle Lewandowski has taken on and exhibited expertly against his former side.

Manuel Neuer, another of the Bayern players carrying a Muller shirt, kept Dortmund at bay at one end – finishing with four saves – before his club's latest outstanding number nine showed Erling Haaland and BVB's team of young pretenders how it is done at the other.

"Lewandowski has proven over several years now that he is a world-class striker," coach Julian Nagelsmann said before the game. "Erling hasn't been in the league that long, although his scoring rate is great."

That proven Lewandowski class brought a brutal, brilliant opener, his header from Serge Gnabry's left-wing cross thumped into the bottom-left corner. The outcome of a chance that was worth a moderate 0.29 expected goals (xG) was never in doubt.

And Lewandowski was involved again, in the box again, when Bayern appeared to put the game beyond doubt four minutes after half-time, waving a leg towards Alphonso Davies' low cross in an attempt at a flick that ran instead for Thomas Muller's tap-in, the late Bayern superstar's namesake having been the third visiting player to hold up a red shirt in a pre-match show of respect.

Perhaps the linesman was a Gerd Muller fan, too, twice ruling in Bayern's favour when Youssoufa Moukoko and Haaland each ran away to score – the second call considerably closer than the first.

There was no ruling out a blistering Marco Reus strike, which briefly threatened Bayern's control, but Manuel Akanji's dallying let Lewandowski in again and the Dortmund fans know exactly how that tends to go. This time with an xG of 0.25 – merely the fifth-best chance of the match – the 32-year-old made it look routine.

A seventh Supercup strike, Lewandowski extended another record that is all his own – albeit in a competition Muller never graced.

The Poland international is Muller's nearest challenger in Bundesliga terms, with 278 goals, and deserves to be counted in such company, even if he has just added to Bayern's reputation rather than transformed it. Lewandowski has also now scored in 14 successive matches for Bayern, which means he needs to score in just two more consecutive games to match another of Muller's all-time records (16, in 1969-70).

Meanwhile, this was not Haaland's night, but he too could have one eye on the sort of standards Muller set. Still just 21, Haaland has 42 goals in 44 Bundesliga games – or one every 84.8 minutes – and Hasan Salihamidzic has acknowledged Bayern would be "amateurs" not to consider signing the striker.

Given the apparent inevitability of a transfer at the end of this campaign, the BVB sensation would seemingly have to join Germany's powerhouse to stay in the Bundesliga and close on Muller or Lewandowski.

Bayern do not need a replacement up front just yet, though, after their latest legend ensured 2021-22 would continue an almost constant theme since Muller broke all barriers, with silverware heading back to Bavaria.

Manchester City saw their main rivals for the Premier League title get off to a flying start on Saturday before the champions stumbled at Tottenham on Sunday.

Son Heung-min continued his phenomenal recent record against City with the only goal, while Pep Guardiola's men drew a blank for a third consecutive game in all competitions. Perhaps there's someone in north London who could help them out with that?

Manchester United and European champions Chelsea revelled back in front of full houses and Liverpool gave newly-promoted Norwich City a reality check.

But those are the bare facts. Let's delve a little deeper to examine some of the quirkier happenings on the Premier League's opening weekend.

Stumbling start for City

Guardiola suggested his stars returning from Euro 2020 and Copa America duty might be undercooked and so it proved. The 1-0 loss at Tottenham Hotspur Stadium puts City in territory they are not used to.

You have to go back to 2008-09 and a 4-2 defeat at Aston Villa for the previous time City lost their opening Premier League fixture.

In that same campaign, Guardiola's fledgling Barcelona tenure got off to an inauspicious start with a reverse against Numancia that indicated little of the treble win that was about to unfold. The Catalan had overseen 11 subsequent opening day wins since then.

Perhaps it was always going to be Spurs who halted his run, Guardiola has now lost more away games against Tottenham (five) in all competitions than any other opponent in his career.

It is also worth considering whether he is chasing the wrong Spurs forward. Only Jamie Vardy (nine) has more than Son's seven goals against City since Guardiola took charge in 2016.
