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.

Paris Saint-Germain had last played in front of a full Parc des Princes on February 29 last year, a 4-0 win over Dijon. It's unlikely many fans in attendance on that day would have contemplated the idea of Lionel Messi being present upon their next visit.

Yet despite Messi not actually being involved, his presence was certainly felt.

The Barcelona great – like the rest of PSG's new signings – was paraded on the pitch before kick-off of Saturday's visit of Strasbourg, simultaneously setting fans' tongues wagging and surely leaving Ligue 1 defenders quaking in their boots, if they weren't already.

As Messi stood there with a big grin on his face, arm around Sergio Ramos of all people, the sheer nonsense of the situation just set in a little more. Previously two pillars of arguably the most famous rivalry in world football, now they're both party to the same 'galactico' project in Paris.

Understandably, the pre-match show helped stir up an incredible atmosphere, and it all seemed to rub off on the players as well, with PSG 3-0 up inside 27 minutes.

But if there was one thing PSG's eventual 4-2 victory suggested, it was that Ramos' arrival is arguably the more important of the two transfers.

After all, Messi wasn't the only one of their soon-to-be first-choice front three absent; Neymar was sat up in the stands next to him, owing to lack of fitness following his Copa America exploits.

But they still had Kylian Mbappe out strutting his stuff, seemingly relishing all eyes being on him, the France superstar tormenting the Strasbourg defence relentlessly with his direct running and astonishing pace.

Perhaps it was a taste of what life might be like at Real Madrid should he choose not to renew in Paris; he was the main man and the star of the show, whereas he'll soon have to share the spotlight with not just Neymar but his old Barcelona pal as well.

That's not to say Mbappe looked anything other than focused on where he was, in what was his 150th Ligue 1 appearance.

Soon after Mauro Icardi – another big name, though one who'll likely be reduced to a back-up role – nodded PSG in front in just the third minute, Mbappe carved open the Strasbourg defence with a disguised pass in from the left, though it was ultimately a little too deceptive as it even caught Georginio Wijnaldum flat-footed.

He was then in the thick of the action as PSG went 2-0 up, cutting in from the left and hammering a ferocious effort that went in off Ludovic Ajorque, and Mbappe did much of the damage to make it 3-0, too.

Stepover. Shimmy. Another stepover and then an explosion of pace. He made himself the tiniest bit of space to squeeze a left-footed cross into the danger zone and Julian Draxler was on hand to tap in.

Mbappe somehow failed to add another himself, shooting at Matz Sels twice after the break. The second of which, in the 62nd minute, was a particularly strong opportunity with an expected goals (xG) value of 0.35 – the one he created for Draxler was 0.90.

By that point Strasbourg had already been given some encouragement, with Kevin Gameiro capitalising on the shoddy awareness of Achraf Hakimi and Thilo Kehrer in the 53rd minute to ghost between them and head in.

Then, swiftly after Mbappe's second miss, Ajorque made a mockery of Presnel Kimpembe as he slashed the deficit to one goal with an emphatic header that also left Keylor Navas helpless.

For a significant part of the second half, Strasbourg looked the better team. PSG had seemingly become comfortable with their lead and that complacency was being capitalised on by the visitors.

But two yellow cards in quick succession for Alexander Djiku essentially spelled game over for Strasbourg, and PSG made it 4-2 soon after through Pablo Sarabia.

Majeed Waris should have pulled one back, his shot into the side-netting seeing him waste a chance with an xG value of 0.38, making it the worst miss of the day.

Mauricio Pochettino's men ultimately survived this scare, but their second-half drop-off will have been a real worry for the head coach and his staff – had Strasbourg got the score back to 3-3, it would have been utterly humiliating.

While this was of course a PSG without Marquinhos, their defensive frailty and seeming arrogance when thinking the game was won had Ramos' signing looking like an absolute necessity.

LaLiga has seen a lot of upheaval over the past few months, none more so than since the start of August as Lionel Messi's future unravelled.

This will be the first season that LaLiga has been without Messi since 2003-04, and as such there are plenty of people suggesting Spain's top tier has subsequently lost much of its appeal.

Be that as it may, even with spending significantly limited among clubs this year, there are still some interesting new arrivals to LaLiga.

Below, Stats Perform uses Opta data to look at five of them…

Memphis Depay, forward - Barcelona, free transfer from Lyon

Granted, Barcelona's rocky financial situation means it is yet to be confirmed if Depay will be registered for the start of the season.

But assuming Depay is involved as Barca begin the campaign against Real Sociedad, he will be under pressure to help make up for the loss of Messi.

His record at Lyon at least shows he should carry a threat, and in theory he will be surrounded by better players at Camp Nou.

Depay scored 76 goals in 178 appearances for Lyon after joining from Manchester United in January 2017 and enjoyed a particularly impressive final season in Ligue 1, finishing with 20 goals to trail only Paris Saint-Germain star Kylian Mbappe (27).

The former PSV youth product's 12 assists and 94 chances created were more than any other player managed in France's top flight in 2020-21.

In all competitions, meanwhile, Depay scored 22 goals last term at an average of one goal every 141.5 minutes, making it his second-best season since arriving.

He massively exceeded his expected goals (xG) tally of 12.38, so perhaps he shouldn't be expected to be quite as prolific, but if he can reach double figures in goals and assists once again, Depay would have to be considered a shrewd signing.

David Alaba, centre-back - Real Madrid, free transfer from Bayern Munich

It has been a difficult few months for Madrid. While caught up in plenty of off-field controversy, they have also lost the centre-back partnership that guided them to so much success. Sergio Ramos and Raphael Varane, as well as their former head coach Zinedine Zidane, are no longer around.

The one signing Madrid have managed to bring in does at least offset one of those losses, as Alaba will offer experience, versatility and all-round quality at centre-back. After all, he made 298 Bundesliga appearances for Bayern, and a player does not reach such figures without being excellent.

He helped Bayern keep 111 clean sheets across those games, did not receive a single red card in the league, and made only two errors leading to goals in the competition, according to Opta data.

Bayern team-mate Thomas Muller is the only other player in Bundesliga history to have won 10 titles, and Bayern had counted on Alaba as their Mr Dependable. Carlo Ancelotti will hope he can form a great partnership with Eder Militao.

Rodrigo De Paul, central midfielder - Atletico Madrid, €35m from Udinese

While Diego Simeone has perhaps been a bit hit and miss when it comes to making the most of creative talents, De Paul appears to be ideal schemer for his new coach.

Providing creativity is De Paul's bread and butter, with his 82 key passes in 2020-21 bettered by only Hakan Calhanoglu (98) in Serie A.

Of those chances, 34 came from set-pieces, highlighting his prowess from dead-ball situations and ranking him fourth in Italy's top flight.

Only five players got more assists than his nine, but all of them massively out-performed their modest expected assists records, which ranged from 3.4 to 6.7. De Paul topped the charts for expected assists with 10.3 xA, evidence that his assists reflected the quality of his service rather than him getting lucky or benefiting from unusually good finishing by team-mates.

Yet the area which highlights a particular compatibility with Atleti is the fact he won more duels (294) than anyone else in Serie A in 2020-21.

Combine that with his league-leading completed dribbles (122) and it paints a picture of a hard-working player who also possesses the quality to get his team on the front foot.

Jose Macias, striker - Getafe, on loan (with purchase option) from Guadalajara

It is fair to say Getafe are not particularly one of LaLiga's most-fashionable sides. Under Jose Bordalas they were more renowned for their aggression and physical style of play, though new boss Michel has significantly different ideas.

In theory, that should immediately make them a more likable proposition for the neutral, and the signing of Macias will only add to the intrigue.

The 21-year-old Mexico international had been linked with numerous clubs with greater status than Getafe, such as Juventus, Borussia Dortmund and Sevilla, but Los Azulones pulled off something of a coup in bringing him to the Coliseum Alfonso Perez on loan with an option to buy.

Macias is the first forward that Guadalajara have sold to a European side since Javier Hernandez left for Manchester United in 2010 and he heads to Spain having netted 12 times in the most recent Mexican Apertura and Clausura campaigns.

His 20 shots on target in the 2021 Clausura was the most by a Mexican player, though it was during a loan spell with Leon where Macias really announced himself, netting 24 times in 38 Liga MX matches.

He didn't quite hit those heights again upon returning to Guadalajara, so the jury is still out to a degree, but there is lots of potential for Getafe to tap into.

Yusuf Demir, winger - Barcelona, €500k loan fee (€10m purchase option) from Rapid Vienna

Barcelona fans need not fear life without Messi, for they have signed the 'Austrian Messi'… or something like that.

Obviously that is a fair bit of pressure for an 18-year-old to have, particularly given he was initially signed for the B team, but he's produced some positive performances in pre-season for the senior side and arrived from Rapid with a burgeoning reputation.

While Demir only started in six of his 25 Austrian Bundesliga appearances (825 minutes) last season, he finished the campaign with a highly respectable seven goal involvements, which averages out at one every 117.9 minutes – only 10 players to play at least 825 minutes had a better record.

Despite only getting the one assist, Demir was a regular source of creativity when he did feature, as highlighted by the fact his 2.7 key passes per 90 was the sixth highest among those to play at least 825 minutes.

But arguably his most notable asset, and the one that inspires the comparison with Messi, is his ability on the ball.

A dynamic and exciting player, Demir attempted 6.3 dribbles per 90 minutes on average, a figure matched by no one who featured for more than 108 minutes last term.

Similarly, he was successful with 3.8 dribble attempts per game, which was also a league high. It was that kind of flair that helped him realise a childhood dream by moving to Camp Nou, and he could have a more prominent role than he may have initially predicted upon his arrival.

If the coming LaLiga campaign can match the previous few months for drama, an epic is in store.

The 2021-22 season gets under way this weekend with Spanish football still reeling from Lionel Messi's remarkable Barcelona departure.

The move to Paris Saint-Germain leaves one of LaLiga's grandest clubs without its talisman, while rivals Real Madrid have also seen their captain depart for the French capital on a free transfer.

Where does that leave defending champions Atletico Madrid and the rest heading into the opening weekend? Stats Perform takes a look.

CHAOS IN CATALONIA

Barca still have plenty of world-class players and will this season be able to count on Pedri, Frenkie de Jong, Antoine Griezmann and, they hope, Memphis Depay.

But the shocking nature of Messi's exit is going to be tough to move on from, even if the club's dire financial situation does not prevent Depay and the Blaugrana's other new signings from being registered.

Messi either attempted (196) or created (77) 46.8 per cent of Barca's 583 shots in 2020-21 – and he missed three games – so Ronald Koeman's side are going to have to completely change the way they play.

He was already missed when out through injury – Barca won 73.7 per cent of the 520 league games in which Messi featured for the club but just 56.7 per cent of the 120 he did not – and that issue is not going away now.

MADRID COPE WITH CHANGE

Money is tight at Madrid too, but Los Blancos have faced that reality, cutting back spending and agreeing the departures of high earners like Sergio Ramos and Raphael Varane.

Despite Zinedine Zidane's exit, they also look in better shape on the pitch on the eve of the new campaign.

Madrid ended last season unbeaten in 18, the best ongoing run in the competition, with only frustrating late-season draws with Getafe, Real Betis and Sevilla – all in the space of five games – leaving them two points shy of Atletico.

They have gone for a familiar face with a proven track record to replace Zidane, Carlo Ancelotti returning after winning 75 per cent of the league games in his first Madrid stint – trailing only Jose Mourinho (76 per cent win rate) among Madrid coaches to oversee 50 matches or more.

ATLETI AT THE TOP

It is a strange phenomenon for Atleti to be both top of the league and not the target of constant transfer enquiries.

Their key men are unlikely to be poached while Barca and Madrid are so short of cash, with the Blaugrana instead reportedly pursuing a deal going the other way, with Griezmann returning to the Wanda Metropolitano.

The development with Messi appears to have put that idea to bed, and Atleti instead spent the week before the season agreeing new contracts for defensive stars.

Those clubs on the outside of the title race looking in are enjoying unfamiliar comforts too, with Europa League winners Villarreal keeping their best players – including Gerard Moreno, whose 23 goals only trailed Messi – and Real Sociedad bringing back the same team that finished fifth.

Unless Ancelotti quickly restores an ageing Madrid side to past glories, this season could be wide open at the summit.

Julian Nagelsmann has long seemed destined to be Bayern Munich coach, and the 34-year-old now has his chance after succeeding Hansi Flick.

He has a lot to live up to. Flick, in his 18-month tenure, Flick led Bayern to two Bundesliga titles, one DFB-Pokal, a Champions League triumph, Club World Cup glory, the DFL-Supercup and the UEFA Super Cup – a remarkable seven trophies.

While Nagelsmann settles into life in the hottest of coaching seats in Germany, his former team RB Leipzig will look to finally make a title challenge last, this time under new coach Jesse Marsch.

Borussia Dortmund scraped into the Champions League places thanks to a super run late in the season, and now Marco Rose will look to build on their DFB-Pokal success in his first season in charge.

Just what can we expect from each of Germany's big three in 2021-22?

Bayern Munich

Bayern ultimately claimed their ninth successive Bundesliga title with ease last term and Robert Lewandowski was once again the driving force. He had to wait until the last kick of the last day, but he finally broke Gerd Muller's long-standing Bundesliga record of 41 goals in a single campaign.

Unsurprisingly, Bayern scored the most goals in Germany's top tier in 2020-21, netting 99 times across their 34 fixtures. Their tally of 483 chances was also by far the most in the division, 54 ahead of second-ranked Leipzig (429) in that regard, though they conceded 44 times while the Leipzig defence under Nagelsmann was the stingiest, with only 32 goals conceded. 

Bayern averaged 65.39 per cent possession and had 1,304 touches in the opposition box, over 400 more than any other side.

However, Nagelsmann does have to contend with the loss of some players who have been crucial to Bayern's dominance. David Alaba has joined Real Madrid, while fellow stalwarts Javi Martinez and Jerome Boateng also left on free transfers.

Dayot Upamecano has made the same switch from Leipzig as Nagelsmann, and the young centre-back adds pace and dynamism to Bayern's backline. Other than that, the squad remains largely the same, with Sven Ulreich having returned after a spell at Hamburg, while Omar Richards arrived on a free transfer from Reading.

Even without much more in the way of incomings, it is difficult to see Bayern letting the chance to make it 10 titles in a row slip from their grasp.

Dortmund

Last season was a difficult campaign for Dortmund, but it was one which ultimately ended successfully. They clinched Champions League qualification and ran riot against Leipzig to lift the DFB-Pokal.

It was a fine parting gift from Edin Terzic, who took over on an interim basis after Lucien Favre was relieved of his duties, and now Rose – whose Borussia Monchengladbach team slumped in the back half of the season and missed out on Europe – will look to reshape Dortmund in his own way.

Renowned for attacking, front-foot football, Rose's style, if all goes to plan, is bound to be a hit with the Dortmund fans upon their return to Signal Iduna Park.

Dortmund may have sold Jadon Sancho, but they still have Norway sensation Erling Haaland, who scored 27 Bundesliga goals last season from 93 attempts, giving him a shot conversion rate of 29.03 per cent, the third-highest in the league out of players to have scored 10 or more times.

Donyell Malen has arrived as Sancho's replacement, and Rose has already been talking up the Netherlands youngster, while goalkeeper Gregor Kobel has arrived from Stuttgart. Like Bayern, Dortmund said goodbye to a club legend in the form of Lukasz Piszczek, but with Marco Reus, Thorgan Hazard, Malen and Haaland complemented by the likes of Julian Brandt and Jude Bellingham, there should be plenty of cause for optimism.

It might well be Haaland's final season at the club, and you would not put it past the youngster, who also set up six goals last term, to propel Dortmund into the title race, back where they belong.

RB Leipzig

There are plenty of quality teams competing with the three leading lights, and it would certainly not be surprising to see Bayer Leverkusen, Wolfsburg, Eintracht Frankfurt or Gladbach mount a serious push for Champions League football.

However, Leipzig have well and truly established themselves as a Champions League regular now, and will be looking to Marsch, who has made the transition from sister club Salzburg, to continue Nagelsmann's work.

Leipzig sold Timo Werner to Chelsea in 2020, and netting just 60 times, they clearly missed the striker. Indeed, midfielder Marcel Sabitzer, with eight goals, was their leading scorer, with forwards Alexander Sorloth and Yussuf Poulsen only managing five each.

In Andre Silva, signed from Frankfurt, Leipzig have a forward who scored more than Haaland in the Bundesliga last season, with the Portugal international finding the net 28 times in 32 appearances.

Silva boasted an impressive 'big chance', as defined by Opta, conversion rate of 55 per cent, while only Lewandowski (137) had more than the former Milan man's 117 attempts. Dani Olmo and Christopher Nkunku – who supplied nine and six assists respectively last season – can provide the creativity, with Poulsen and Sorloth able to offer Marsch a variety of attacking options. Caden Clark, who is starring in MLS, will arrive before the turn of the year, while Dominik Szoboszlai is almost like a new signing, given he is yet to feature for the club since his arrival in January due to injury.

Leipzig have faced a reshuffle in what had been a strong defence, with key man Upamacano departing while Ibrahima Konate has also left for Liverpool, though the acquisition of Salzburg's highly rated Mohamed Simakan shows the production line is still ticking along, and a Champions League place will be the minimum expectation. 

The new Premier League season has not even begun yet and we're already enjoying some enthralling narratives.

Beyond the mundane matter of who might win the league, who will beat the drop and how thick the VAR lines will be, there are some tantalising stories we'll be following closely in the coming weeks.

Below, Stats Perform takes a look at some of the big talking points...

Blue Benitez

Predicting football is often a fool's game – especially in an era when Lionel Messi no longer plays for Barcelona – but Rafael Benitez at Everton? Who saw that coming?

The Spaniard is back in the Premier League, two years after walking away from Newcastle United, having been tempted by the same project that won over Carlo Ancelotti before the lure of a Real Madrid return became too great.

Benitez was a fans' favourite at Newcastle, arguably as much as he was at Liverpool, where he reached two Champions League finals including the unforgettable triumph in Istanbul. His connection to the red half of Merseyside meant his decision to head to Goodison Park raised the eyebrows of some and the blood pressure of others. In fact, only one man has ever managed both clubs: William Edward Barclay, Everton's first boss in 1888 and Liverpool's manager from 1892. We'll forgive you if you don't remember.

The scrutiny on Benitez, who has recorded 11 wins against Everton in his coaching career, will be severe. He has the credentials, but if he cannot quickly prove he is the man to realise the dreams of owner Farhad Moshiri and challenge the 'big six', the pressure could become pretty uncomfortable.

Virgil return lifts Reds

For a while, it seemed everything would be okay. In the first 11 games after Virgil van Dijk was injured against Everton last October, Liverpool conceded just six goals and kept as many clean sheets. Perhaps the loss of the Netherlands colossus would not be quite so damaging.

Of course, as injuries in defence piled up and confidence in their title chances waned, Liverpool's season ended up being one of major disappointment even though a strong final few weeks saw them snatch a Champions League spot.

Van Dijk's impact cannot really be disputed: since his move to Anfield in January 2018, Liverpool have won 75.8 per cent of matches with the centre-back in the side and only 54.3 per cent without him. They average 2.4 points per game with him (compared with 1.9 without), and even score more goals on average (2.3 compared with 1.8) when he's playing. No wonder fans began to count down the days to his return.

On Saturday, we can finally expect to watch Van Dijk in competitive action again, with Jurgen Klopp confirming he is fit to start the season. He could even begin his partnership with new signing Ibrahima Konate against Norwich City at Carrow Road. How Liverpool's campaign progresses over the opening few weeks, and how Van Dijk's return goes, might just tell us whether another title tilt is on the cards.

Rom-ember us?

Two of the biggest transfers in this pre-season have seen stars returning to England: Jadon Sancho, who finally got his Manchester United move for £72.9million a year after Borussia Dortmund had demanded a sizeably bigger sum; and Romelu Lukaku, who is heading to Chelsea for roughly £93m.

Sancho left Manchester City for the Bundesliga as a teenager and promptly became one of Europe's standout attacking players, with 50 goals and 57 assists in 137 appearances. Ole Gunnar Solskjaer wanted a player to get fans on their feet, and he's almost certainly found it: Sancho completed 48 multi take-ons (beating more than one player with a dribble) in the Bundesliga, at least 14 more than any other player in his time in Germany.

For Lukaku, it's a case of unfinished business at Chelsea, the club he left back in 2014. The standout performer for Inter last season, with 30 goals and 11 assists in all competitions, he propelled his side to their first Serie A title since 2010 before taking up the chance to return to Stamford Bridge, where a consistent goalscorer could be decisive to their Premier League title hopes.

Sancho and Lukaku initially struggled to convince managers to give them a shot as youngsters in the Premier League. They return as elite players determined to prove a point. Given the costs involved, the pressure will be on both to perform – and quickly.

Did Jack hammer Harry's City hopes?

Manchester City are not exactly frugal in the transfer market, but rarely will they willingly pay over the odds for an individual. That's what made their willingness to spend £100million on Jack Grealish, a player with 12 senior international caps and zero Champions League experience, a touch surprising.

This is not to suggest Grealish is not a good player, of course. This is a man who was involved in a remarkable 376 open-play attacking sequences over the past two seasons for Aston Villa, a team who finished 17th and 11th in those campaigns. It's just notable that Pep Guardiola felt it was warranted to smash City's transfer record by nearly £40m to sign yet another midfielder, especially given what's going on – or not going on – with Harry Kane.

Kane was expected to be City's marquee signing in this window but, as of now, his future is unclear. He is finally due to return to Tottenham training this week but whether he is involved against City in their opening game is harder to know. And if City were willing to spend nine figures on Grealish, you can expect Spurs chairman Daniel Levy to demand top dollar for last term's golden boot winner, who has three years left on his contract.

Will City stump up the cash? Will Kane try his best to force Spurs' hand? Will he be staying in north London for at least a few months more, his form undimmed, the goals flowing as normal? It will be fascinating to watch.

LaLiga is arguably harder to call than ever before heading into 2021-22 – Barcelona no longer have Lionel Messi to guide the way and Real Madrid have seen significant upheaval, so surely the smart money is on defending champions Atletico Madrid?

Diego Simeone's men won the title in 2020-21 after watching Barca and Madrid trade success for seven years and look in good shape given they've not lost any major players. But can you really write off the 'big two'?

Well, you shouldn't, according to Stats Perform predictions.

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.

Without further ado, let's look at what could occur over the 2021-22 LaLiga season.

ANCELOTTI DELIVERS THE GOODS

Carlo Ancelotti's back at the Santiago Bernabeu, and so – it seems – will the Spanish title. The Stats Perform model calculates Madrid have a 42.3 per cent chance of taking the crown back from their local rivals.

In fact, if the model proves accurate, Atletico may not even finish in the top two, as their 18.7 per cent chance is a fair bit smaller than Barca's 30.4 per cent likelihood of winning LaLiga.

However, it's worth pointing out that, because the model is based on historical data points and results, the Barcelona that appears here is one that has had Messi in the team for past 17 years.

It's entirely reasonable to expect Barca to see a significant drop-off given they'll no longer have the greatest player of all time on their books – as such, a 30.4 per cent chance of winning the title might actually be quite generous.

THE BIG FOUR?

The 2020-21 season was the tightest LaLiga title fight in recent memory. Although Atletico were 11 points clear at one point, with five matches left there were just three points separating first from fourth.

In that respect, it was the closest title race LaLiga had ever seen in a 20-team campaign (1987-1995, 1997-present) and the least predictable since 2006-07, when Madrid, Barca and Sevilla could all win the league on the final day of the season.

Sevilla's challenge ultimately faded before that stage in 2020-21 but they've managed to keep Julen Lopetegui, their coach, and their squad is largely unaltered for the time being.

The prediction model makes them fourth favourites for the title (6.8 per cent) and far better placed to take the final Champions League spot (69.4 per cent) for the third year in a row than their likeliest challengers Villarreal (36.2 per cent).

There was a 15-point gap between fourth and fifth last season – this is the closest to a 'big four' Spain has had in years.

FOUR TIPPED FOR RELEGATION TUSSLE

Rayo Vallecano, Real Mallorca and Espanyol were the three to come up from the Segunda last season. While most people would ordinarily point to the promoted sides as the most likely to be relegated, the prediction model disagrees.

It gives Mallorca a 30.7 per cent likelihood of going straight back down, and Espanyol are at 17.6 per cent – neither of those are among the bottom three, though Rayo (45.9 per cent) are seen as the second favourites to head back to the second tier.

But it's Elche (57.9 per cent) who are the clear front-runners in this regard, and then it looks agonisingly close for the third and final relegation spot.

According to the predictor, it's likely to be neck-and-neck between Deportivo Alaves (41.1 per cent) and Cadiz (41.9 per cent).

Bayern Munich are entering a new era under Julian Nagelsmann, but it looks unlikely much will change when it comes to their dominance of the Bundesliga in 2021-22.

It could be another good season for Wolfsburg, but things are not looking too good for Greuther Furth, according to Stats Perform predictions.

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.

Let's see what we can (likely) expect from the new Bundesliga season...

NO STOPPING NAGELSMANN

It looks like Nagelsmann's first season at the Allianz Arena is set to be a positive one. The predictor model gives Bayern a huge 84.3 per cent chance of winning the title for the 10th time in a row.

With the loss of David Alaba mitigated by the signing of Dayot Upamecano, there is little reason to doubt Bayern's credentials even as their new coach gets to grip with the job. Indeed, they are given just a 0.1 per cent chance of failing to qualify for the Champions League, while the likelihood of relegation stands at a big, fat zero.

Borussia Dortmund might have lost Jadon Sancho but they are still expected to be Bayern's biggest challengers, the Stats Perform model giving them an 11.7 per cent chance of a first title since 2012. RB Leipzig, third last term, have just a 2.9 per cent chance of finishing first, while Wolfsburg are fourth-favourites at a lowly 0.6 per cent. At least their chances of a Champions League spot stand at a strong 49.6 per cent.

TOP-FOUR TENSION

Last term's top four look likely to repeat their league positions, but don't discount Eintracht Frankfurt from a surprise Champions League place – they're given a 30.8 per cent chance of qualifying for Europe's top tournament.

Similarly, Bayer Leverkusen have just under a one-in-four chance of a top-four spot, with Borussia Monchengladbach at 14.7 per cent – slightly above their likelihood of a Europa League place.

BOCHUM OF THE PILE

Bochum won the second-tier title last term to return to the Bundesliga for the first time in 11 years. Their stay is not expected to be a long one, however: the Stats Perform model gives them a 54.8 per cent chance of being relegated in 2021-22.

Still, it could be worse. Greuther Furth are the favourites for the drop at 59.7 per cent, with a 15.8 per cent of finishing the season in the relegation play-off spot.

Cologne (27 per cent) and Augsburg (25.8 per cent) are the other favourites for the drop, while all four sides are given 18th out of 18 as their lowest probable finish.

Arminia Bielefeld fans should not feel too comfortable, either, given their side have a 19 per cent chance of going down.

Opportunism was the name of the game for Atletico Madrid in 2020-21 and, ultimately, it led them all the way to the title.

First, they pounced on the opportunity to sign Luis Suarez, then Diego Simeone's squad enjoyed a commanding start to the season that left their rivals playing catch-up.

Lionel Messi's situation at Barcelona contributed to the Blaugrana being slow out of the blocks, and although Atletico almost contrived to throw it all away in the latter stages of the season, they proved their resilience in seeing it out.

While opportunism led to success then, this season Atletico arguably find themselves on the cusp of a new, dominant era. Barca are in an even greater mess than 12 months ago and no longer have Messi to bail them out, while Madrid's only major signing has been David Alaba – in contrast, they have lost Sergio Ramos and Raphael Varane is Manchester bound too. Add Zinedine Zidane's departure to that and it is very much a picture of transition at the newly refurbed Santiago Bernabeu.

Atletico, meanwhile, have not lost any key players and have even improved their midfield options with the signing of Rodrigo De Paul. It was not so long ago that Simeone's future seemed uncertain, but the past year has brought out a new side in him and that's helped Los Colchoneros reign in Spain.

Flexible Simeone turns over a new leaf

Throughout Simeone's time in charge of Atletico, there has been a common theme – you can either call it consistency or inflexibility, but it essentially depends on whether you are a critic or a fan.

However, it is difficult to say he was inflexible last season by any stretch of the imagination. Now, whether that was decisive in their title triumph is impossible to say, yet it does show Simeone is perhaps not the one-trick pony some insist he is.

For much of his decade at the helm, Simeone has almost religiously set his teams up in a rigid 4-4-2 formation, or at least something not too dissimilar. A back four has been the cornerstone of his systems. According to Opta data, he only ever started a match with a back three or five six times before 2020-21.

Yet, in the championship-winning campaign, Atletico lined up with a back three or five in 23 of their 38 LaLiga matches. Simeone had amassed a group of players with wide-ranging skillsets that aided versatility, and he truly embraced that.

Yannick Carrasco's work-rate saw him turned into a wing-back; Kieran Trippier's arguably suspect defensive capabilities became less of a concern because he was stationed further up the pitch. In attack, Luis Suarez and whoever partnered him – usually Joao Felix or Angel Correa – offered unpredictable movement that often saw them push out wide to create space for Marcos Llorente to run into.

Of course, that didn't occur all the time, but it is notable how all 12 of Llorente's goals came from either positions in the box or central positions just outside the area despite a lot of his work coming down the right flank in tandem with Trippier.

This flexibility in the final third also seemed to contribute to their effectiveness off the ball. Their 43 shot-ending high turnovers was bettered by only Barcelona and Eibar, though that figure equated to 15.3 per cent of their total high turnovers (281).

That percentage was better than both of those teams above them in the category, suggesting Atletico were more effective at turning those situations into danger, despite their PPDA of 11.5 only being the 12th lowest in the league.

But the overriding feeling looking back at Atletico in 2020-21 was the only real ammunition Simeone's critics had – that he was inflexible – seems to have lost relevance.

De Paul is Simeone's ideal schemer

It was only a matter of time before De Paul sought a new home after an excellent five-year spell in Italy with Udinese. It was there that he got his career back on track after struggling to make much of an impact with Valencia during his previous attempt to succeed in Spain.

He was a regular throughout his five years in Serie A but enjoyed his finest campaign of all in 2020-21, displaying a skillset that looks an ideal fit for the requirements of a Simeone team.

Throughout Simeone's 10 years as Atletico coach, his signings of creative players have tended to be hit and miss, with it a common perception that his intense demands both in training and during matches can sometimes stifle more mercurial talents who are not used to such workloads.

But De Paul, who is comfortable playing both centrally and out wide, has shown plenty of evidence he should be up to the challenge.

Providing creativity is De Paul's bread and butter, with his 82 key passes in 2020-21 bettered by only Hakan Calhanoglu (98) in Serie A. Of those chances, 34 came from set-pieces, highlighting his prowess from dead-ball situations and ranking him fourth in Italy's top flight.

Only five players got more assists than his nine, but all of them massively out-performed their modest expected assists (xA) records, which ranged from 3.4 to 6.7. De Paul topped the charts for expected assists with 10.3 xA, evidence that his assists reflected the quality of his service rather than him getting lucky or benefiting from unusually good finishing by team-mates.

Yet the area that highlights a particular compatibility with Atleti is the fact he won more duels (294) than anyone else in Serie A in 2020-21.

Combine that with his league-leading completed dribbles (122) and it paints a picture of a hard-working player who also possesses the quality to get his team on the front foot.

His creativity and dribbling abilities are two facets that Atletico don't necessarily have in abundance in their central midfield options, yet he balances those with a genuine work ethic. De Paul could well be an absolute triumph of a signing.

Joao Felix's time?

Joao Felix's 2019 arrival at the Wanda Metropolitano was met by the clamouring of Simeone critics suggesting this was the signing that would finally see the renowned pragmatist cut loose and suddenly become the entertainer many hoped he could be.

It didn't work out that way. In fact, their haul of 51 LaLiga goals in 2019-20 was the lowest they had managed since scoring just 46 in 2006-07 – they somehow became even tougher to watch.

This did not do much to convince those adamant Simeone was to blame for Joao Felix's form – many people called for the young talent to be given a "free role" that allowed him to play without the shackles normally associated with the coach's disciplined system.

But for a period in 2020-21, there were real signs that Joao Felix was beginning to find his feet. While he was not necessarily roaming as some might have envisioned, his role - being more of a withdrawn forward towards the left - in the first half of last season saw him become one of LaLiga's standout players.

One theory was that Suarez's signing helped Joao Felix significantly. After all, the Uruguayan enjoyed a near-telepathic on-pitch relationship with Messi and has always boasted exceptional off-ball intelligence. He can make great players look even better.

For example, prior to Atletico's 1-0 win over Barca at the Wanda Metropolitano on November 21 last year, Joao Felix had already created the same amount of chances for Suarez (four) as he had for anyone else in all of 2019-20.

But it's fair to say the Portugal talent did not manage to maintain his status as a standout player for the full season. Bouts of illness, injuries and a suspension all hampered him after the turn of the year as he made just five of his 14 league starts after January 1. In fact, his final total of starts was seven fewer than in 2019-20.

Joao Felix's productivity was not as impressive as a result. He went from creating 1.5 chances per game to 0.9 and appeared far less willing to run with the ball, attempting 26 dribbles compared to 43 before January 1.

Sure, his assists count went up from two to three, though between January 1 and the end of the season his expected assists (xA) value was just 0.77, suggesting he benefited from some help from his team-mates.

Joao Felix's influence in build-up play did not change dramatically, only going down to 4.0 shot-ending sequence involvements from 4.9, which was not massively better than he managed in 2019-20 (4.64), but he lacked the sharpness to make the difference at the top end of the pitch as often.

Hopefully 2021-22 will have less upheaval for him and allow for greater consistency. With Messi gone, LaLiga needs a new headline superstar – Joao Felix has the talent, but whether Atletico and Simeone can truly harness it is another matter entirely.

Nevertheless, Atleti excelled even when Joao Felix was not hitting the heights expected. As they see Barca and Madrid appearing significantly weaker, Simeone and his players are heading into 2021-22 as the team to beat.

To paraphrase the apocryphal question asked of Abraham Lincoln's widow, "Aside than that, Mr Laporta, how was the lunch?"

When Lionel Messi jetted into El-Prat last Wednesday, it was to complete the formalities of a long-awaited contract extension that would commit him to the club of his life for the rest of his career.

At least, that's what the six-time Ballon d'Or winner and pretty much everyone else thought until he sat down for lunch with club president Joan Laporta on Thursday. After that, all hell broke loose.

"We had everything agreed but, at the last minute, it couldn't happen," he said at his tearful Sunday news conference, with the rampaging shambles of Barca's financial, internal and political affairs having put paid to the best laid plans.

Messi is now a Paris Saint-Germain player. It will be a jarring thing to type and read for some time, and the claims, counter-claims and recriminations over how Barcelona allowed things to reach this point of collapse will rumble on for some time.

It feels like a barely relevant sidenote that four days on from their greatest ever player addressing the media and being paraded around Paris, Barcelona will host Real Sociedad to begin their LaLiga campaign. What, if anything, can Ronald Koeman and his players salvage from the wreckage?

The Barcelona Way

The delayed election campaign that secured Laporta's return to the top job – his initial term between 2003 and 2010 having overseen the transformative tenures of Frank Rijkaard and Pep Guardiola – was a fraught one for Koeman.

Victor Font, one of Laporta's rival candidates, pledged to bring in club great Xavi if he was successful, while the eventual winner's support for Koeman was tenuous and conditional at best.

After a chaotic 2019-20 season, where Ernesto Valverde's lamentable sacking cleared the way for Quique Setien to surrender LaLiga to Real Madrid and oversee the humiliating 8-2 defeat to Bayern Munich in the Champions League quarter-finals, Koeman was not a universally popular choice and easily viewed a stop-gap appointment.

Whereas Messi wanted to stay but had to leave this time around, last August he wanted to leave but had to stay – relations with Laporta's predecessor Josep Maria Bartomeu having broken down. On the field, the Blaugrana were inevitably a little bit all over the place.

But after a chastening 2-1 loss to Cadiz on December 5, Barcelona and a rejuvenated Messi went 19 games unbeaten in LaLiga. It was almost enough for an unlikely title success, but the run ended with a 2-1 defeat away to Real Madrid on April 10.

Koeman lost both Clasicos and his Barca only took a point from Atletico Madrid, failing to score in either game against the eventual champions. There were heavy Champions League losses to Juventus and PSG, and Koeman's record in big games was and is an obvious concern.

Yet, it was fairly bizarre to see the Dutchman treated with such disregard during the electioneering, which ran parallel to the long undefeated streak. After tinkering with various formations earlier in the season, Koeman had settled upon a 3-4-3 in which his team thrived.

Nevertheless, in May, it was reported by Mundo Deportivo that Laporta demanded Koeman commit to Barca's classic 4-3-3 and brand of football married to the club's traditions. A stay of execution would be dependent upon one of Johan Cruyff's former disciples committing to the Barcelona Way.

Back to the future

Looking at their performances from last season, it is easy enough to spot elements of classical Barcelona in Koeman's side.

They scored the most goals in LaLiga and had the highest expected goals (xG) figure of any team, indicating they cumulatively created a better quality of chances than their rivals.

The way they got to this point was also very Barca.

No side in LaLiga had a higher average sequence time than the Blaugrana's 14.27 seconds, while their average of 5.52 passes per sequence was also a league best. They were the only team to average above five.

In terms of sequences featuring 10 or more passes, they were streets ahead with 910. The next most 10+ pass sequences came from Madrid with 662. As a consequence, Barcelona also ranked top for build-up attacks – open-play sequences of 10 or more passes that end either with a shot or a touch in the opposition box.

Now as then in the glory days of Guardiola, you spend a lot of time chasing the ball against Barcelona.

Pedri enjoyed a breakout campaign so good he's only just been allowed to finish it, shining for Spain at Euro 2020 and the Olympic Games, while the evergreen Sergio Busquets ticked away in his customary style to average 95.52 passes per game. The next best midfielder in LaLiga on that metric was Madrid's Toni Kroos on 85.76.

Frenkie de Jong developed a knack of chiming in with some important goals from midfield after the turn of the year, while also showing his versatility by slotting into the back three when injuries and circumstances required.

Consider the presence of Riqui Puig and teenage sensation Gavi and the "take the ball, pass the ball" part of the Cruyffian legacy remains in safe hands, albeit with the fairly large assumption that there remains room for all of them on the accounts.

Pressing concerns

The other key facet of the teams in which Messi rose to his place at the top of the world game was their work without the ball.

Teams being at their most vulnerable in transition is now an accepted reality of the modern game, but Guardiola's Barcelona swarming opponents as soon as they lost the ball altered perceptions of what was required of elite teams in terms of intelligent commitment to the cause.

Barca operated under their six-second rule, which had nothing to do with anybody dropping food on the floor. They attempted to retrieve possession within six seconds of losing it via immediate and intensive pressing. If this was not possible, they would fall back into a defensive shape to guard against opponents now settled in possession and more able to play through the press.

Pressing methods and teams' aptitude in dealing with them have obviously evolved since Barcelona scared the life out of European football a little over a decade ago, but the principles remain. If a team wishes to play a high-possession game with a high defensive line, their defending from the front as to be impeccable.

In 2020-21, Koeman's side were merely quite good in this regard. Passes per defensive action (PPDA) is a metric that indicates how well a team presses. The lower the average number of passes an opponent is allowed to make outside the pressing team's defensive third before being met with a defensive action – such as a tackle, interception or a foul – the better the press.

Barca's 10.6 PPDA put them sixth best in LaLiga last season, below Celta Vigo, Real Sociedad, Sevilla, Getafe and Real Betis. Although they scored the most goals from high turnovers (seven), this can be attributed to the sharp finishing of Messi and others, as their 37 shot-ending high turnovers were only the eighth highest.

They are not numbers that suggest Laporta's fantasy of seeing a whirring 4-3-3 back in motion is one grounded in reality. By comparison, Luis Enrique's "MSN" Barca of 2014-15 averaged a staggering 7.0 PPDA. Had Messi remained, his capacity to do this sort of work is diminished, but that is now a puzzle for Mauricio Pochettino to solve.

Messi's great friend Sergio Aguero is one of the attacking reinforcements, although a calf injury means he will be sidelined for 10 weeks. If the masterful Argentina striker's body still allowed him to press with suitable intensity, he would probably still be with Guardiola at Manchester City.

Memphis Depay is fit to start the new season and some of the onus will fall upon the Netherlands international to sharpen Barca up a little.

He comes from a Lyon side who forced more shot-ending high turnovers than any other in Ligue 1 last season (62), while his 25 instances of winning possession back in the final third placed him joint fifth among forwards in the French top-flight. 

Antoine Griezmann won the ball 24 times deep in opposition territory last term in LaLiga, alongside 37 tackles and 100 recoveries, all of which were highs among Barca forward. He and Depay could certainly prove a useful nuisance in tandem.

Getting on with the job

Of course, it is not entirely certain Barcelona will be able to register Depay with LaLiga in time to face Real Sociedad, such is their parlous financial state.

Laporta claims this will not be a problem. But then, he said he'd re-sign Messi and essentially ran for election on a pledge he spectacularly failed to fulfil.

If it turns out Barca passed up on Messi because they decided to reject LaLiga's deal with CVC Capital Partners and its associated cash injection in favour of remaining in cahoots with Real Madrid and Florentino Perez's doomed Super League project, it's unlikely holding Laporta to account over whether or not Koeman plays 4-3-3 will be the top of anyone's agenda. It should be noted Madrid president Perez said it was "impossible" for him to have had such an influence, in response to allegations levelled by former Espai Barca Commission member Jaume Llopis.

One of the major reservations surrounding Koeman's appointment was whether he was the man to win Messi more Champions Leagues, with the clock ticking on the great man's career.

This might feel like an absurd grasp for positives and Koeman would be better off if the greatest player of all time was in his squad, but he is at least without one of the big over-arching narratives that Barca have specialised in both constructing and crushing themselves with over recent years.

Valverde was saddled with "only" winning LaLiga as European glory painfully slipped away. If Koeman can wrest back domestic control in these conditions, it would be recognised as a brilliant achievement in its own right. The atmosphere among fans back in Camp Nou might be perilous in the initial post-Messi weeks, but a few wins will place a defiant siege mentality within reach.

Since Cruyff was appointed head coach in 1988, this will be the first season without the late Dutch master, Guardiola or Messi – those three giants of the modern Barcelona – having any active association with the club. It is time for an institution on its knees to let go and turn the page.

Koeman put together a team that functioned well amid considerable turbulence last season and should be allowed to improve upon that template with the fine players that still remain, free from any Mes Que Un Club self-flagellation as Laporta tends to the dumpster fire he inherited and chucked a vat of petrol all over last week.

For Paris Saint-Germain's Champions League rivals, the most daunting thing is that they have seen this all before.

Lionel Messi has been unveiled as the Ligue 1 giants' latest superstar signing, reuniting him with friend and former team-mate Neymar at the Parc des Princes.

As Barcelona did between 2014 and 2017, though, PSG have more besides the great Argentina and Brazil number 10s.

At Camp Nou, Luis Suarez arrived from Liverpool to quickly link up with his two fellow forwards and fire Barca to European glory.

This time, Kylian Mbappe, already at PSG, is the third man in a frightening front line.

On paper, it is a terrifying prospect, but can the PSG trio work together as Barca's famous 'MSN' did for three years?

Goals and assists galore

Across the three seasons Messi, Suarez and Neymar played together in Catalonia, the three players ranked first (149), third (128) and joint-sixth (89) for goal involvements in Europe's top five leagues.

Only four players registered both 30 goals and 30 assists in that period and three of them played for Barca. Cristiano Ronaldo, of course, was the other.

Barca and Ronaldo's Real Madrid accounted for six of the 10 highest-scoring LaLiga seasons by a team in the competition's history over the space of those three years.

Spanish football has never before or since been as exciting – and Messi, Suarez and Neymar (and Ronaldo) were at the forefront, pushing one another on.

In that time, Messi and Suarez combined for a goal every 198 minutes in the league (36 in total from 144 chances created together). Messi and Neymar between them created 2.1 chances for one another per 90 minutes, resulting in 22 assists, while Suarez and Neymar were also an effective combination with 26 assists.

Messi and Neymar had already had a single season together in 2013-14, so it was Suarez's seamless introduction that was most impressive. His 43 assists over those three years tied with Messi and trailed only Kevin De Bruyne (47).

This time it is Messi's turn to join an established duo, with Neymar and Mbappe setting an alarming standard in their limited time together on the pitch.

Injuries to Neymar have limited them to 3,552 minutes – less than half as many as Messi and Suarez over a longer period – but they have combined for 102 chances (2.6 per 90) and 21 assists (one every 169 minutes).

Missing the middle man

The similarities in this context are clear, but Mbappe and Suarez are very different players in a number of ways, including their positioning. Messi and Neymar have changed their roles since they first combined, too, and that is why this front three might require a little work at first.

In 2014-15, their first season together at Barca, the Blaugrana trio's touch maps told the tale of a balanced forward line.

A huge 60.1 per cent of Neymar's touches were on the left flank in the attacking half, with 33.4 per cent concentrated in an area just outside the box.

With the former Santos man staying left, Messi and Suarez were able to link up across the rest of the final third. Messi started from the right but took 22.5 per cent of his touches in the very centre of the attacking half, the same zone in which Suarez enjoyed 17.9 per cent of his touches.

Suarez, with 20.4 per cent of his touches on the left wing in the final third and 23.1 per cent on the right, was capable of drifting out to either side to create space but would rarely occupy these spaces for an extended period. That is a crucial contrast to Mbappe.

Mbappe last season took 57.9 per cent of his touches on the left flank in the attacking half, with only 11.6 per cent on the right. That left-sided share actually dwarfed Neymar's 46.3 per cent in the same position, indicating both their lack of playing time together and a slightly freer role for the world's most expensive player.

Indeed, the natural striker is the one of the three PSG forwards who uses the least of his touches through the centre. Messi, like Neymar, has become even more of a central figure since breaking away from the 'MSN' attack, last term taking 25.1 per cent of his touches in a central position just outside the box.

These touches speak to a fluid PSG approach, but they may need Mbappe to stretch the play down the middle and provide a focal point – something Suarez did that suits neither Messi nor Neymar.

Pressing from the front

Barca's front three of 2014-15 were not just brilliant in possession, they were also an effective force without the ball, winning it back to quickly get on the attack once more.

Luis Enrique's men allowed just 7.0 passes per defensive action (PPDA), not letting their opponents rest and forcing 370 high turnovers that contributed to starting their attacks 44.7 metres upfield on average.

PSG are starting from a slightly lower, if still impressive, base in a pressing sense this season. They allowed 8.9 PPDA and forced 337 high turnovers to start attacks 43.7 metres upfield on average.

It is likely Mauricio Pochettino, who employed a pressing game at Tottenham, will want to move up another gear in his first full season at the club, but that might be easier said than done with the players at his disposal.

In 2014-15, Messi led all LaLiga forwards in winning possession 37 times in the final third. Neymar (26) was second and Suarez (16) joint-11th. Across Europe's top five leagues, only Karim Bellarabi (also 37) could match Messi in this regard.

Messi has never since tallied as many final-third recoveries, with that rate of 1.0 per 90 now halved to 0.5 at the age of 34.

Neymar, in limited minutes, reached a new high by winning possession 1.3 times per 90 in 2020-21, yet his tackle rate of 0.9 is considerably down on 2014-15's high of 1.5.

Mbappe twice recovered the ball in the final third in PSG's opening league game of this season against Troyes and last year peaked with 23 such examples across the campaign, but they counted among 59 total possession gains – Messi and Neymar each passed 100 in 2014-15.

So, a revival of that devastating Barca press in Paris seems unlikely at this stage, even if Messi and Neymar, with a new partner, look primed to thrill again.

Whether the silky interplay is as effective without the other side of the game is a query that should be answered by May.
