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).

Borussia Dortmund CEO Hans-Joachim Watzke says that it is "unfair" that Paris Saint-Germain have signed Lionel Messi.

PSG unveiled Messi on Wednesday following his free transfer move from Barcelona on a bumper two-year deal.

Watzke, who has had to ward off strong interest in Dortmund's prized asset Erling Haaland this off-season, said Qatari-owned PSG's economic position was unfair.

“It is a fact that PSG has more economic resources than 85 per cent of other European teams," Watzke said as reported by L'Equipe.

"It is clear that this is an unfair competition that has already been rife for too long but I am by no means jealous.

"Frankly, it wouldn't be my cup of tea to have to kneel down every fourth morning in front of the Emir of Qatar."

PSG have signed Messi along with Georginio Wijnaldum, Sergio Ramos and Gianluigi Donnarumma on free transfers this off-season, bumping up their player wages.

The Parisians also spent €60million to sign Internazionale full-back Achraf Hakimi, having purchased Mauro Icardi for the Nerazzurri 12 months ago for €50m.

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.

LaLiga's deal with CVC Capital Partners has been labelled "totally illegal" by the Spanish Football Federation (RFEF).

The €2.7billion (£2.3bn) arrangement that was announced last week would see private equity firm CVC acquire 10 per cent of the league's commercial business.

The other 90 per cent of the investment was earmarked to boost cash-strapped clubs in the top two tiers of Spanish football amid the coronavirus pandemic.

However, the deal – which must be approved by two thirds of the 42 clubs involved at Thursday's general assembly – was heavily criticised by Real Madrid and Barcelona.

Madrid and Barca allege the agreement affects all clubs' audiovisual rights for the next 50 years, with Los Blancos threatening to take legal action against LaLiga and president Javier Tebas as they were not properly consulted.

In a long statement released on their official website on Wednesday, the RFEF said it is also totally opposed to the proposal that has been put forward.

The statement read: "This operation, carried out with the absence of the slightest publicity and concurrence in the selection of the successful bidder, has two parts. The one related to the commercialisation of audiovisual rights, on the one hand; and the rest of the LNFP businesses, which make up a heterogeneous group, on the other.

"Regarding the agreements between the LNFP and CVC related to the audiovisual rights of sports clubs and corporations, the RFEF must express its opposition. 

"Not only for legal reasons, which will undoubtedly generate numerous litigation derived from the agreement and may put its own viability in doubt, since it is intended to force some legal institutions to the extreme; but also for economic reasons, since the rights of clubs and SADs are heavily taxed for the next fifty years in exchange for a small amount of money. 

"But the most important thing is that the agreement increases inequality and, in a capital and definitive way, makes a reasonable evolution of the format of professional football competition in Spain impossible. 

"Causing that in practice and in application of the agreement the competition is petrified without the possibility of evolution or can only be modified when a third party outside the sports structure so decides or agrees, a fact that flagrantly violates the law and the European sports model. 

"In addition, forget about the clubs that play non-professional competitions that, at the time of their promotion to professional competition, will see that their income is reduced by CVC's remuneration, without having obtained any benefit from the contribution of that entity."

The RFEF also claims the agreement with CVC does not account for the clubs who will be promoted to LaLiga further down the line, which would see their income reduced if not paid upfront.

"If there are clubs who, with their own rights, wish to indebt themselves voluntarily, they are free to do so, whether at market rates or extortionate ones, but not through a totally illegal agreement which obliges everyone else, via a false attribution on the part of the LNFP of rights it does not own," the statement continued.

"We consider this attempt to bypass the law and create an agreement which is economically dreadful and deplorable in terms of the future of Spanish football while, in contrast, excellent for an investment fund and other possible beneficiaries.

"The RFEF must also warn that it will not allow during these 50 years any reduction in the contribution from audio-visual rights given to the lower tiers of football."

Real Madrid president Florentino Perez has denied claims that he played a part in Lionel Messi leaving Barcelona for Paris Saint-Germain.

Barca announced last week that their greatest ever player would not be staying on at Camp Nou, despite agreeing terms for a new contract.

Messi's 21-year association with the Catalan giants formally came to an end on Tuesday when putting pen to paper on an initial two-year deal with PSG.

Barca president Joan Laporta insists the club did all that they possibly could to keep hold of the Argentina captain, but "financial and structural obstacles" stood in the way.

However, ex-Espai Barca Commission member Juame Llopis claimed this week Laporta was convinced by CEO Ferran Reverter and Madrid chief Perez to let the forward leave in order to free up funds.

The comments were made after LaLiga announced a €2.7billion deal with CVC Capital Partners to boost clubs, with 90 per cent of the investment earmarked for their use.

Llopis, who resigned from his post after Messi's departure, told Cadena SER: "The new CEO [Reverter] is in charge. 

"I know that everything has to go through the CEO, everything has to be signed by the CEO and not the president.

"The CEO threatened Joan Laporta with his resignation, and he has an ironclad contract, if he signed [LaLiga's deal] with CVC.

"Laporta was pressured by his CEO and, on the other hand, Florentino convinced him. 

"Between the two of them they convinced him that he has to kick Messi out [of Barcelona] and not sign with CVC."

Madrid and Barca have since stated their objections regarding the CVC deal due to a disagreement over audiovisual rights.

And Perez has now issued a statement in response to Llopis' remarks, insisting it was "impossible" for him to have any sway over Messi's future at Camp Nou.

"Given the statements made by Jaume Llopis, a former member of the Espai Barca Commission, I want to state the following," the statement read. 

"It is flatly false that he has been friends for a long time with the CEO of FC Barcelona, ​​Ferran Reverter, since he is a person with whom I have only met twice in my life.

"One of those occasions was four months ago and the other last Saturday at the meeting that took place in Barcelona with President Joan Laporta and President Andrea Agnelli. 

"That was after the official communication on Messi had already taken place. 

"Therefore, it is impossible for me to have had any influence either on Messi's departure or on any other FC Barcelona decision. 

"So, I hope that Jaume Llopis rectifies these statements that do not correspond to the truth as soon as possible."

Madrid kick off their 2021-22 LaLiga campaign with a trip to Deportivo Alaves on Saturday.

Xavi feels sympathy for Lionel Messi and his former club Barcelona following the superstar forward's switch to Paris Saint-Germain.

Messi held a tearful news conference on Sunday to confirm the end of his 21-year stay at Camp Nou ahead of completing a move to PSG on Tuesday.

The six-time Ballon d'Or winner revealed both he and Barcelona did everything possible to agree a new deal, but it was made impossible by "financial and structural obstacles".

Xavi, who won 24 trophies playing in the same side as Messi prior to departing Barca in 2015, is upset that the Argentina international was effectively forced out of the door.

"I'm just so sad for Leo," Xavi, who is now managing Qatari club Al Sadd, told The Times. "It's a pity to see he and the club couldn't find a solution.

"I know that Leo wanted to stay, but in the end it could not be sorted.

"The only thing I can say now is that I will miss him a lot. It's even hard for me to picture Messi with a shirt other than Barca's. 

"It's sad for Leo, especially for how I saw him emotionally at the Camp Nou the other day, but for FC Barcelona as well."

As Barcelona get set to begin a new season without Messi for the first time since 2003, there will be plenty of onus on others in Ronald Koeman's squad stepping up.

One of those who has already made big strides in his first full campaign at Camp Nou is young midfielder Pedri, who also impressed for Spain at Euro 2020 and the Olympics.

He played more passes in the opposition half (461) than any player at Euro 2020.

Pedri's 421 successful passes was bettered by only four players, with the 18-year-old completing 65 of the 66 attempted in the semi-final loss to Italy – that one misplaced pass coming in extra time.

And Xavi can see similarities between Pedri and another Barcelona icon in Andres Iniesta, who spent 16 years in Barcelona's first team.

"Pedri is unbelievable. The kid has Iniesta's profile of a player, for sure," Xavi said.

"Watching him play at his age, doing what he does, leaves you with the only answer: he'll be great. Actually, he already is so impressive, but he can be even better."

While Spain's campaign ended at the last four stage, England reached the final on home soil before suffering a cruel defeat to Italy on penalties.

Xavi was impressed by what he saw from Gareth Southgate's side and in particular a couple of their midfielders.

"I've seen England at a fantastic level. They have absolutely everything in the squad. Well, actually they were not champions just because of a penalty," he said.

"This generation is young, physically strong but also great technically. With this group of players, they'll always be competitive.

"I can see them fighting for the World Cup, without a shadow of a doubt. They are almost there.

"I think that sooner rather than later they'll have this spark of luck you need to win trophies.

"I have also been hugely impressed by the two midfielders, Declan Rice and Kalvin Phillips. I did not know them that well, but they were superb.

"You can see a centre-back like John Stones and how he plays the ball out from the defence.

"Next to him there's [Harry] Maguire, who drives up the ball to split the opponent's pressing. 

"How the full-backs and wing-backs behave for the team . . . there are details that speak volumes of Southgate's work."

Euro 2020 was a rather mixed tournament for Phil Foden, who started England's first two matches but struggled to make an impact and was largely overlooked from that point on.

"I think he is an unreal talent for a lot of reasons," Xavi said of the Manchester City midfielder. "He has an amazing work rate, but also his decision-making is ace. 

"He's strong, quick, has a sense of goal, great passer and shooter... There's everything in the pack.

"I would have loved to see more game time for Foden. When you have this number of talented players, all I can think of is putting them on the pitch. 

"I understand it's very tough to make changes with the squad Southgate had. There were a lot of options in his hands and only eleven could play. 

"But it's a pity to see so many special talents with not much playing time."

Lionel Messi has targeted Champions League glory with Paris Saint-Germain after finalising a "complicated" exit from Barcelona.

The Argentina international's 21-year association with Barca officially ended on Tuesday when joining PSG on a two-year deal with the option of a third.

Six-time Ballon d'Or winner Messi looked certain to sign a new long-term deal at Camp Nou, but financial complications at the LaLiga club forced him out of the door.

Less than a week after Barca announced the 34-year-old was to leave, he was unveiled as a PSG player at the Parc des Princes on Wednesday.

Reflecting on a whirlwind week, Messi admits it was difficult departing the only club that he has represented in his career to date.

"It's been a very hard moment after so many years," he said at a news conference. "It was a difficult change after so much time. But the moment I arrived here I felt very happy. 

"I'm really enjoying my time in Paris and want to begin training now, starting this new moment in my life.

"The club were really quick with negotiations. It's been a really easy process, even if it was a tricky situation. I want to thank them for sorting out any problems."

He added: "Everything that happened to me this week has been very strange. It's been emotional. I can't forget what I lived and experienced at Barcelona.

"But I feel impatient and ready for this new life with my family. I'm very happy. This whole week I've been going through up and downs, but we are processing all of this little by little every day. 

"I was in Barcelona when the press talked about the move. The people in Paris were already outside. It was incredible to see them in the streets. I really want to see them in the city, in the stadium. It will be an incredible year."

Messi departs Barcelona having scored 672 goals and assisted 265 more for the Catalan giants across 778 appearances.

He won 35 trophies at Camp Nou, including four Champions League triumphs.

PSG have never won the competition, coming closest to doing so last year when losing to Bayern Munich in the final, but Messi is hopeful of lifting the famous trophy once again.

"I still want to play and I still want to win, as I did at start of my career," he said of his ambitions with the French giants. "This club it is ready to fight for all the trophies.

"That is my goal. I want to keep growing and winning titles. That's why I came here to this club. I hope we can make it happen."

Asked specifically about PSG's Champions League hopes, Messi said: "This team is ready. There are some new transfers, but they have been close and are ready to win it.

"I have just come here to help. My dream is to win this trophy again and I think Paris is the best place to do so.

"It was very complicated to exit Barcelona without knowing where I would go. Barcelona was my home since I was a kid. 

"I knew I'd arrive in a strong team that was aiming to win the Champions League, which I love to win. I know my goals and Paris' goals are the same. 

"It's difficult to win it, you need a strong group. Luck is also a factor. Sometimes the best team in the world does not win. We want to win the Champions League."

Messi may cross paths with Barcelona in UEFA's showpiece competition this coming campaign, potentially giving the superstar forward a chance to sign off at Camp Nou in front of supporters.

"It would be very nice to go back, hopefully with fans," Messi said. "It would be very strange to play at home, there in Barcelona, in another shirt, but it could happen."

Kylian Mbappe has "no excuse" to leave Paris Saint-Germain following Lionel Messi's arrival, according to club president Nasser Al-Khelaifi.

Messi was unveiled at a press conference at the Parc des Princes on Wednesday while thousands of fans gathered outside the stadium to welcome the superstar forward.

The Argentina captain signed a two-year deal, with the option of a further 12 months, after Barcelona were unable follow through on the terms they agreed with the 34-year-old due to financial problems.

Mbappe has less than year remaining on his contract with the Ligue 1 club but PSG president Al-Khelaifi believes the France forward has no option but to stay and play alongside Messi and Neymar.

"Everyone knows the future of Kylian," said Al-Khelaifi. "He's a competitive player who wants to win trophies - he's said that himself.

"He wanted a competitive team, [with Messi] there is no excuse. He can't do anything else but stay."

Al-Khelaifi insists PSG are in no danger of breaching UEFA Financial Fair Play (FFP) regulations after luring Messi to the French capital.

Asked about FFP, he replied: "A very great question, thank you. We have checked and we knew we had the capacity to sign Leo.

"What Leo brings to the club is huge, that is what you media need to focus on, not the negative, the positive."

Nasser Al-Khelaifi expects Lionel Messi to win "a lot of trophies" for Paris Saint-Germain after the Argentina captain was unveiled at the Parc des Princes on an "historic" day for the Ligue 1 club.

PSG confirmed the signing of mercurial forward Messi on a two-year deal on Tuesday, with the option of a further year.

The six-time Ballon d'Or winner left Barcelona as the LaLiga giants were unable to afford to keep the 34-year-old.

Messi scored 672 times in 778 appearances for the Blaugrana, winning the Champions League four times and claiming 10 LaLiga titles.

PSG president Al-Khelaifi believes he will add many more honours at PSG, declaring the signing of Messi to be "just the start".

"I am very happy and proud to present Lionel Messi as PSG player. It is an historic day for the club and football world and is a fantastic moment for us," Al-Khelaifi said as thousands of fans gathered outside the stadium to welcome their new hero.

"It will be very exciting for our fans and fans worldwide. It is amazing what we have tried to achieve.

“We have a big ambition, a football project. We are very proud of where we are today. There is no secret this agreement is with this best player in the world." 

Al-Khelaifi added: "There was a great desire on both sides to make this happen.

"This is just the start as the hard work will start now, on the pitch and off the pitch, but most important the person next to me has won a lot of trophies and I'm sure he will bring a lot more trophies to this club."

Ossie Ardiles believes Lionel Messi will form a stronger bond with Mauricio Pochettino than he has with any other manager after the Argentina captain's sensational move to Paris Saint-Germain.

Messi has signed a two-year deal with PSG after Barca were unable to keep the superstar forward for financial reasons.

Former Argentina midfielder Ardiles expects the six-time Ballon d'Or to revel in playing under his compatriot Pochettino.

Ardiles also feels the presence of fellow Argentinians Angel Di Maria, Mauro Icardi and Leandro Paredes can only be a positive for Messi.

"Messi is not just Argentinian, but a global player. Of course he is able to play with anyone and he is also able to play at any style of game. This is how enormous his game is," Ardiles told Stats Perform News.

"it helps to have that many Argentinians. Mauricio, for instance, is from the same city [as Messi], Rosario. Obviously, they speak same language.

"It will be very important for Lionel Messi to have Mauricio there. Messi got along well with almost every manager, but I think it will be even better with Mauricio.

"Being with Di Maria, Paredes and Icardi will help, but I also think these players don’t play the full Argentinian style. They are very global. Icardi has been in Italy and now at PSG. The same for Paredes or Di Maria, being also in English football. From that point of view, there won’t be any issue, for sure."

Messi scored 672 times in 778 appearances for the Blaugrana, winning the Champions League four times and claiming 10 LaLiga titles.

The 34-year-old was reduced to tears during an emotional farewell press conference and Ardiles fears for Barca following the departure of the inspirational skipper - especially considering the desperate state of the club's finances.

Ardiles added: "Barca stays very, very hurt. Actually, the situation is absolutely critical. To lose the best player in the world is tough.

"He has spent 20 years in the club, he is the symbol, the captain… he is everything. I really think there are coming very tough times for Barcelona.

"We were used to seeing Barcelona leading the game and being the team to be beaten. If you wanted to lift the Champions League or LaLiga you had to beat Barcelona. That will all change with Messi's departure. Absolutely.

"On the other hand, Barcelona spent so much money. That's why it is in this situation now. Like people say, it has likely been [the fault of] the previous board, but the fact is Barcelona has spent much more than they could.

"So, nowadays, Barcelona cannot go to the market and buy the best player in the world, not even keep him in his own squad. And it can't either go to the market to buy the current stars, as they don't have money to do it.

"However, Barcelona is a very big club, an extraordinary club and of course it will be back. But I think it will take a long time."

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.

Paris Saint-Germain have once again rocked the world of sport after they confirmed the signing of Lionel Messi.

As bizarre as that may look written down, the deal is complete with the Argentina forward signing a two-year deal following his Barcelona departure.

Barca announced last Thursday that their dire financial situation meant they could not bring their greatest ever player back under LaLiga's salary restrictions after his previous contract expired in June. He had spent his entire career at Camp Nou.

But the Parc des Princes now beckons and he will form probably the most-feared front three in world football alongside Kylian Mbappe and his old friend Neymar.

It's with the Brazilian where Stats Perform starts in this look at a selection of other sporting deals that shocked the world.

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. But maybe Messi will be the final piece of the puzzle...

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.

Lionel Messi has joined Paris Saint-Germain on an initial two-year deal after calling time on his 18-year Barcelona career.

Messi became arguably the greatest footballer of all time at Camp Nou, scoring 672 times in 778 appearances, but his prolific spell came to an end after Barca's dire financial situation forced the club's hand.

The six-time Ballon d'Or winner had been a free agent since July 1, though the expectation was for him to sign a new contract at the Catalan club.

However, last Thursday's announcement he would not re-sign with Barca due to "financial and structural obstacles" prompted PSG to move quickly.

The 34-year-old was said to be a target a year ago when he stated his desire to leave, but ended up staying and playing out the final year of his contract.

Having teased the signing throughout the day on social media, PSG finally confirmed it with a video that included footage of their new recruit standing in the centre circle of the Parc des Princes. 

He will wear the number 30 shirt and while PSG confirmed the initial contract length, it is widely reported there is an option in place for a further year.

Messi will be reunited with former Barcelona team-mate Neymar, who joined PSG in a world-record deal in 2017, and link-up with Kylian Mbappe, with that trio set to form a devastating forward line.

Mbappe's future is in doubt with the France star having only one year left on his contract, though there has been talk that Messi's signing could convince him to agree new terms with PSG.

During his time at Barcelona, Messi claimed four Champions League triumphs alongside 10 LaLiga titles.

The forward finally won a senior international trophy in July, firing in four goals and adding five assists to secure Argentina's first Copa America success since 1993.

Messi's acquisition marks the culmination of a transfer window that has seen PSG add significantly to their squad, signing Gianluigi Donnarumma, Sergio Ramos, Georginio Wijnaldum and Achraf Hakimi after missing out on the Ligue 1 title and losing in the Champions League semi-finals last season.

Lionel Messi is a Paris Saint-Germain player. It may still seem a bit hard to take in, particularly as such a scenario looked so unlikely as recently as last week, the deal is complete.

Messi has signed a two-year deal at the Parc des Princes and will form probably the most-feared front three in world football alongside Kylian Mbappe and his old friend Neymar.

Barcelona's dire financial situation meant they could not bring their greatest ever player back under LaLiga's salary restrictions.

Messi's contract expired at the end of June and, although Barca president Joan Laporta confirmed the two parties had reached an agreement, the numbers made a deal impossible. The Blaugrana chief confirmed at a monumental press conference that the deal to keep the talismanic forward at Camp Nou was dead.

Step forward PSG. Just as they gutted Barca four years ago when triggering Neymar's release clause to leave them utterly helpless, the Parisians have swooped in again and wasted no time about it. A matter of hours had passed between Laporta's news conference and the emergence of widespread reports suggesting Paris beckoned.

What Messi goes on to achieve in France remains to be seen, but using Opta data, Stats Perform looks at some of the incredible feats that have make him such a colossal signing for PSG.

Messi played 778 games for Barcelona in all competitions, scoring 672 goals and providing 265 assists across those games. That amounts to 937 goal involvements during his Barca career, which began as a 17-year-old.

Previously a one-club man, his first appearance for Barcelona came under Frank Rijkaard against Espanyol in October 2004, while his first goal arrived seven months later against Albacete at Camp Nou from a Ronaldinho assist.

Brazil great Ronaldinho was the last Barcelona player to wear the famed number 10 before Messi took that shirt in 2008 and made it his own.

But Ronaldinho does not feature among the top assisters for Messi goals, a list that is led by Luis Suarez (47). Dani Alves assisted 42 of the attacker's goals and third is Andres Iniesta with 37, six more than fellow legendary midfielder Xavi.

Messi played under eight different coaches during his time with Barcelona. Of those, he featured most often (219 appearances) and scored the most goals (211) during Pep Guardiola's tenure.

However, the 60 goals Messi scored in 50 games under the late Tito Vilanova – an average of 1.20 goals per match – was his best goals-per-game return with a single coach.

Perhaps unsurprisingly, Messi's lowest average goals-per-game ratio was during the Rijkaard era at the start of his career (0.38), followed by the 0.63 managed under Quique Setien between January and August 2020.

Messi's most prolific season as a Barcelona player was in 2011-12 when scoring a remarkable 73 goals in all competitions and providing a further 28 assists, setting a personal record in both categories.

Indeed, the forward netted 79 goals for his club across the calendar year in 2012, which is a record amount by a single player. His next most prolific year was 2010 when registering 58 times.

In more recent years, Messi managed 51 goals in 2016, 50 goals in 2017, 47 goals in 2018, 45 goals in 2019 and 26 goals in 2020 – a steady decline that he had already rectified this year, having scored 28 times in the first half of 2021.

He is the only player to have scored 10 or more goals in LaLiga in 15 consecutive seasons.

Messi's 672 goals for Barcelona were scored against 82 different teams. Sevilla were his favourite opponent, finding the net against them 38 times in 43 appearances.

Atletico Madrid were next on that particular list, with Messi bagging 32 goals in that fixture, followed by Valencia (31), Athletic Bilbao (29) and bitter rivals Real Madrid (26), making him the leading all-time scorer in El Clasico.

In terms of individual goalkeepers, Diego Alves was Messi's most-frequent victim, the former Almeria and Valencia man having conceded 21 goals against the Argentina superstar.

Real Madrid legend Iker Casillas was joint-third with 17 goals against, one less than the 18 Messi put past Gorka Iraizoz.

Messi is of course synonymous with Camp Nou, a ground where he has scored 394 goals in 381 games at an average of 1.03 per match. Madrid fans will be particularly sick of him as he has scored 15 times in 22 games at the Santiago Bernabeu – his second favourite venue.

That is followed by Vicente Calderon, Atletico's old home (14 goals in 20 appearances). Deportivo La Coruna's Riazor (13 in eight) and Sevilla's Ramon Sanchez-Pizjuan (13 in 18) complete the top five.

At the opposite end of the spectrum, Messi has played more times at Bayern Munich's Allianz Arena (three) without scoring than at any other stadium for Barcelona. He is also without a goal in two trips to English grounds Anfield and Old Trafford.

Messi's other notable records and achievements

– Messi is the all-time LaLiga top scorer with 474 goals and is the second-highest scorer ever in Europe's top five leagues behind Cristiano Ronaldo (476).

– He scored in 21 consecutive LaLiga games between November 2012 and May 2013, a record for a player in the competition's history.

– The Newell's Old Boys product is one of only two players to reach 100 goals in Champions League history (120), alongside Cristiano Ronaldo (134).

– Messi was the first player to score five goals in a Champions League match, doing so against Bayer Leverkusen in March 2012 at Camp Nou.

– The Argentina forward is one of six players to score more than 50 goals in Copa del Rey's history and the only one to score in six different finals in the tournament (Telmo Zarra scored in five).

Lionel Messi will help Paris Saint-Germain make history, according to club chairman and chief executive Nasser Al-Khelaifi.

PSG secured Messi's signature after the forward had failed to agree fresh terms with Barcelona, who are enduring financial difficulties amid complications with LaLiga.

The 34-year-old moves to the Parc des Princes having scored 672 times in 778 appearances for his former club and furthers PSG's already remarkable depth of attacking talent.

After confirming Messi's arrival on Tuesday, Al-Khelaifi said: "I am delighted that Lionel Messi has chosen to join Paris Saint-Germain and we are proud to welcome him and his family to Paris.

"He has made no secret of his desire to continue competing at the very highest level and winning trophies, and naturally our ambition as a club is to do the same.

"The addition of Leo to our world class squad continues a very strategic and successful transfer window for the club. Led by our outstanding coach and his staff, I look forward to the team making history together for our fans all around the world."

Messi joins former colleague Neymar as he prepares to form a startling front three with the Brazil forward and France star Kylian Mbappe.

The signings of Sergio Ramos, Gianluigi Donnarumma and Georginio Wijnaldum alongside Achraf Hakimi strengthened Mauricio Pochettino's men, but Messi's historic move could take PSG to a new level.

Having been pipped to the Ligue 1 crown by Lille last term, PSG started their quest to reclaim the title with a 2-1 win at Troyes on Saturday and will hope the addition of Messi can inspire them to a first Champions League success.

Messi has won four Champions League titles with Barcelona alongside 10 LaLiga triumphs.

The forward also guided Argentina to their first Copa America success since 1993, scoring four goals as he sealed his first senior international trophy in July.
