Lionel Messi showed exactly why he was given a lucrative contract as his 650th Barcelona goal helped Ronald Koeman's side to a slender 2-1 win over Athletic Bilbao.

A report by El Mundo claimed the deal Messi signed at Camp Nou in 2017, which expires at the end of this season, is worth more than €555million.

He demonstrated his value to this Barca team midway through the first half on Sunday with his 49th successful free-kick strike for the Catalan giants.

Jordi Alba put through his own net early in the second half to draw Athletic level, but Antoine Greizmann ensured Barca leapfrogged Sevilla and Real Madrid into second - 10 points behind leaders Atletico Madrid - with a close-range finish 16 minutes from time.

Unai Simon twice denied Barca inside the opening seven minutes, first pawing away Messi’s clipped effort from close range before diverting Griezmann’s powerful drive over the crossbar.

There was little the Athletic goalkeeper could do to deny Messi after 20 minutes, the Argentinian whipping a sumptuous free-kick into the top right corner from 25 yards.

Ronald Araujo fizzed an effort wide soon after, while Ousmane Dembele lashed over from a promising position shortly before the interval as Barca dominated.

Athletic drew level four minutes after the interval, however, as Alba turned Raul Garcia's left-wing cross into his own net under pressure from Oscar De Marcos at the back post.

Simon superbly kept out Miralem Pjanic's header shortly before the hour mark, while Griezmann nodded wide from Dembele's teasing cross.

The France international had the final say, though, sliding home Oscar Mingueza's low cross into the roof of Simon's net to seal a fourth consecutive win in all competitions for Barca.

Lionel Messi scored his 650th goal for Barcelona with a sumptuous free-kick against Athletic Bilbao on Sunday.

The Argentina international whipped a shot into goalkeeper Unai Simon's top-left corner from 25 yards midway through the first half to put Barca 1-0 up in their LaLiga clash at Camp Nou.

Messi was in the headlines earlier in the day when leaked details of his eye-watering contract emerged.

A report by El Mundo claimed the deal Messi signed in 2017, which expires at the end of this season, is worth more than €555million.

The six-time Ballon d'Or winner scored his first goal for Barca in May 2005 at the age of 17, beautifully lobbing Albacete goalkeeper Raul Valbuena.

He has gone on to become far and away the club's record scorer, overtaking Cesar Rodriguez's previous mark of 232 in 2012.

Lionel Messi's contract details becoming public knowledge was not the fault of Barcelona, the LaLiga club have claimed.

A report by El Mundo claimed the deal Messi signed at Camp Nou in 2017, which expires at the end of this season, is worth more than €555million over the course of four years.

That would mean the six-time Ballon d'Or winner is in possession of the most lucrative contract in sports history - something that jars against Barcelona's worsening financial plight.

Accounts for the 2019-20 season showed the club's gross debt had reached €820m as the coronavirus pandemic began to take a considerable toll on their finances.

A fractious presidential election is set to conclude in March, with a strained relationship between Messi and the former board, headed by ex-president Josep Maria Bartomeu, having played a part in the superstar forward sensationally trying to force a transfer away from Barcelona last August.

In that context, Barca moved quickly on Sunday to offer assurances to their captain and pledged to take legal action against El Mundo.

"In view of the information published today in the newspaper El Mundo, in relation to the professional contract signed between FC Barcelona and the player Lionel Messi, the club regrets its publication given that it is a private document governed by the principle of confidentiality between the parties," a statement read.

"FC Barcelona categorically denies any responsibility for the publication of this document and will take appropriate legal action against the newspaper El Mundo, for any damage that may be caused as a result of this publication.

"FC Barcelona expresses its absolute support for Lionel Messi, especially in the face of any attempt to discredit his image, and to damage his relationship with the entity where he has worked to become the best player in the world and in football history."

Barcelona return to action on Sunday at home to Athletic Bilbao in LaLiga, where they remain 10 points behind leaders Atletico Madrid despite a run of four consecutive top-flight wins.

Messi, who was red carded for the first time in his Barca career against Athletic earlier this month, has contributed 15 goals and four assists in all competitions in 2020-21.

Lionel Messi's Barcelona contract is the biggest in the history of sport, landing the superstar forward more than €555million over four years.

That is the astonishing claim made by El Mundo, with the Spanish newspaper reporting on Sunday that it had obtained details of the deal signed by the 33-year-old in 2017.

The mega-money agreement, which expires in June this year, would see Messi receive up to €555,237,619 across four seasons, providing a number of conditions are met.

Messi was at the centre of a major transfer storm when he attempted to force a move away from Camp Nou last August, but was left frustrated when Barca refused to sanction an exit.

Amid a fraught presidential election campaign, it has remained apparent that all is not well at the Catalan club, whose financial worries are cast in a fresh light after El Mundo's stunning front-page revelations, with the outlet claiming to have laid hands on a copy of "the most sought-after document".

In addition to annual earnings in excess of €138m – dependent on some variables – the report says Messi received a renewal fee of over €115m, and a loyalty bonus just shy of €78m.

The Argentina international, who also rakes in millions in image rights, is said to have earned more than €500m from the eye-watering deal so far.

Barca's accounts for the 2019-20 season showed gross debt had reached €820m, with the coronavirus pandemic having further dented their outlook.

Against the backdrop of those financial woes, Messi's desire to leave, and with a fractious presidential election not due to be concluded until March, Barca are still off the pace in LaLiga despite a run of four consecutive top-flight wins.

Ronald Koeman's side are 10 points behind leaders Atletico Madrid ahead of Sunday's visit of Athletic Bilbao.

Messi, who was red carded for the first time in his career earlier this month, has contributed 15 goals in all competitions.

Barcelona made a mistake not selling superstar captain Lionel Messi at the start of the season, according to Rivaldo.

Messi is out of contract at the end of the current campaign and the record six-time Ballon d'Or winner appears likely to leave on a free transfer amid strong links to Paris Saint-Germain and Manchester City.

The 33-year-old attacker had tried to exit Camp Nou prior to the start of 2020-21 before opting to remain with the LaLiga giants.

As Barca struggle financially amid the coronavirus pandemic, former star Rivaldo wrote in his Betfair column: "Barcelona were not in good financial health pre-pandemic, but things got nasty in the last year and beyond Lionel Messi's almost inevitable departure, the club may need to sell some more important players to generate income.

"As I mentioned previously, the club's board made a mistake by not selling Lionel Messi while he was still under contract, something Real Madrid did with Cristiano Ronaldo receiving around €100million in exchange [from transfer to Juventus].

"It's sad to see such a talented and valuable player leaving Barca for free when the club is going through so many financial problems.

"But looking to potential transfers that might occur, I think Phillipe Coutinho time may have be coming to an end. He has admirers in England and perhaps Barcelona could generate some good income with his sale, allowing them to keep others like Ousmane Dembele and Antoine Griezmann.

"The Brazilian never managed to show his best football in Spain, and since his better moments happened in Premier League I'm sure there will be clubs interested in his services and available to pay considerable amounts, although not quite what Barcelona paid to Liverpool!"

Barca are third in the table and 10 points adrift of leaders Atletico Madrid as they prepare to host Athletic Bilbao on Sunday.

Athletic stunned Messi's Barca in the Supercopa de Espana final earlier this month.

Paris Saint-Germain boss Mauricio Pochettino said every coach in the world would want a player of Lionel Messi's quality at their disposal.

Messi, 33, is out of contract at Barcelona at the end of the season and the six-time Ballon d'Or has been heavily linked to PSG and Manchester City.

Pochettino only took over at PSG at the start of the month but is already facing questions over Messi's potential arrival.

The former Tottenham boss, though, said every coach in the world would want Messi.

"Sometimes words are unnecessary. With the question you ask me, everything is understood," Pochettino told AS.

"What coach in the world would not want to have a player of the calibre of which you are telling me? I totally understand the question, but it is looking for a controversy.

"It is a dangerous question if a word of mine is taken out of context … Pochettino will come disrespectfully, Pochettino talks about this, Pochettino talks about that."

Pochettino has previously spoken of the bond he shares with Messi thanks to their connection to Newell's Old Boys, where both were in the youth system.

While the 48-year-old paid tribute to Messi, he is also preparing to meet the star forward when PSG face Barcelona in the Champions League last 16.

"There is nothing left to say. I respect and admire him so much that I prefer never to say anything or refer to him. It is the best tribute you can do to someone," Pochettino said. 

"We share the two of us who have worn the Newell's jersey and that is something very big. That bond unites us. 

"That he is one of the best players of all time I will not discover and when we meet we will fight for our interests."

Kylian Mbappe will be at Paris Saint-Germain "for many years to come", according to head coach Mauricio Pochettino.

Real Madrid have been heavily linked with a move for World Cup-winning attacker Mbappe, whose contract with PSG is due to expire at the end of next season.

The 22-year-old has scored 106 goals and set up a further 54 in 147 appearances for PSG. Since his debut for the club on September 8, 2017, the only players in the top five European Leagues to have registered more goal involvements are Robert Lewandowski (184) and Lionel Messi (205).

Mbappe is in talks with the club about a renewal but has never hidden his admiration for Madrid boss Zinedine Zidane.

Pochettino is not worried, though, and believes Mbappe's future is at the Parc des Princes.

"Who doesn't love Kylian? He makes himself loved, with his smile, his face and his energy," Pochettino told Marca.

"At the age of 19 he was a world champion [with France], impressive things have happened to him, but he is special and different, with a lot of emotional intelligence.

"He has a lot of potential to develop but he is already [someone for the] present, not just the future. It's a challenge and a good thing to work with this kind of talent, it makes you a better coach. You give this type of player a solution and he gives you five back.

"There are a lot of rumours, but I think he will be at PSG for many years to come, and that's the club's hope. We are counting on him for as long as we are here.

"It's true that he has to make a decision [on his future], but he seems happy and very committed to this project."

PSG are open to the possibility of signing Messi from Barcelona, with the six-time Ballon d'Or winner able to leave Camp Nou on a free at the end of the season.

Asked if having Messi in his team would make him a better coach, Pochettino replied: "Whatever I say will be misunderstood, and I love what I have. Great footballers fit in any league and any team."

He was far more forthcoming when discussing Sergio Ramos, another high-profile player that will be a free agent at the conclusion of the campaign if he does not sign an extension with Madrid.

"After one month [at PSG] I am finding players with great leadership. The great [players] are able to play and coexist in different projects and cultures, but I am very respectful," said Pochettino.

"PSG's strategy has been the same for years, ever since we signed Ronaldinho: to look at market opportunities and bring in those who can improve what we have. We will see in the coming months.

"Here, Ramos would find a great club with the obsession to always win. PSG are one of the biggest [clubs] in the world."

Barcelona booked their place in the Copa del Rey quarter-finals as goals from Lionel Messi and Frenkie de Jong sealed a 2-1 win over Rayo Vallecano on Wednesday. 

Ronald Koeman's side had looked set to follow Real Madrid and Atletico Madrid in losing to lower-league opposition when Fran Garcia gave Segunda Division side Rayo the lead shortly after the hour-mark. 

As is so often the case, though, Messi pulled Barca level soon after with a close-range finish. 

That set the stage for the impressive De Jong to secure Barca's progression 10 minutes from time.

The first clear sight of goal did not come until the 20th minute, De Jong looping an effort from six yards onto Stole Dimitrievski's crossbar.

The visitors somehow failed to take the lead 10 minutes before the interval when Dimitrievski initially pawed away Trincao's strike before Riqui Puig's follow-up was diverted onto the crossbar by Ivan Martos.

Antoine Griezmann and De Jong had further chances, but Barca were ultimately unable to make their superiority count at the break.

Messi clipped the top of the crossbar with a free-kick three minutes after the restart before the Argentina international blazed over after being played clean through soon after.

Barca were made to rue those misses in the 63rd minute when Fran Garcia turned home from almost on the line after Neto had parried Alvaro Garcia's cross into his path.

Messi restored parity six minutes later, however, sliding in from six yards after being teed up by Griezmann.

De Jong ensured there would be no need for extra time to settle the result, stroking home from a similar position to Messi from Jordi Alba's cross.

Paris Saint-Germain have disrespected Barcelona by publicly discussing a move for Lionel Messi and the Spanish club should take action, says Joan Laporta.  

Messi's future remains unclear as his contract at Barcelona continues to wind down. The talismanic forward was linked with Manchester City having made clear his desire to leave in the previous transfer window, though he ended up remaining at Camp Nou to see out his current deal.  

Negotiations over a renewal are not helped by the uncertainty over the identity of the next president at the Spanish club, though an election date is now set for March 7.  

Laporta is one of the remaining candidates in the running and has made clear the importance of making Messi an offer that helps convince him to stay – and is not happy with how PSG have talked about potentially signing the 33-year-old.  

Leonardo, sporting director at the Ligue 1 champions, said this month that "great players like Messi will always be on PSG's list", his comment coming after ex-Barca player Neymar fuelled speculation last December by declaring his desire to play alongside his former team-mate again in 2021.

"The club has to be able to make a good proposal to Messi so that he understands and accepts it," Laporta - previously Barca president between 2003 and 2010 - told the media on Wednesday. 

"I would understand any response from Leo. He has to know the situation of the club and this is urgent. The situation is consolidating; he is free to negotiate with another club, and Barcelona are without a president. 

"PSG allow themselves to publicly say they want to sign Messi. Barcelona cannot allow this. It is disrespectful, even more so coming from a club-state that breaks the rules.

"We have to work with UEFA and FIFA on this. PSG must abstain from [talking about Messi]. It is out of place for another club to speak about him - and there is no president to respond."

Laporta also made clear his position over the potential signing of Eric Garcia, the Manchester City centre-back strongly linked with a return to Spain.

A January move has been rumoured but Barca's financial troubles may make a deal difficult, particularly with the player set to be out of contract at the end of the season.

"I remain in the position I had when this possibility was raised. If a player wants to come to Barca, he has to prove it and if in June he would come for free," Laporta said in reference to the defender.

"It is hard for me to understand why we would have to give money to a competing club.

"I do not understand that the manager attributes the power to negotiate a salary or to pay money now when in June it would not have to be paid, even more so taking into account the economic situation of the club."

Barcelona head coach Ronald Koeman insists his players are not worried by the club's financial situation amid concerns around spiralling debts.

Barca's latest financial figures, dated August 17 but only released this month after their previous AGM was postponed, indicate their total debt has now exceeded €1.1billion.

Their short-term debt has risen to €730m, having increased by €225m since the 2018-19 season largely due to the impact of the coronavirus pandemic: specifically, the lack of matchday revenue as games continue to be played behind closed doors, and the reduction in tourists visiting the Camp Nou facilities.

Although Barca top the 2021 Deloitte Football Money League with total revenues of €715.1m, the stark numbers released by the club paint a concerning picture for prospective new presidents Joan Laporta, Victor Font and Toni Freixa.

Last November, it was announced the players had agreed to a salary reduction that would save the club €122m and help to avoid widespread layoffs of non-playing staff, but interim president Carlos Tusquets claimed last month that the squad would not be paid for January due to the precarious financial situation.

Speaking ahead of Wednesday's Copa del Rey clash with Rayo Vallecano, Koeman stressed the senior squad was dully focused on keeping their trophy push alive.

"Barca is a great club that has been affected by COVID and suffers more than others, also from the tourism side of things," he said. "But all the big teams can take numbers that aren't good, not just here.

"The players are focused and not worried about this subject. We're concentrating on our work."

When asked if some Barca salaries were too high, Koeman replied:  "The club makes the contract and the player accepts it or not. We have to train and win games and trophies. We have all helped the club with the salary reduction."

He added on the subject of January wages not being paid: "I don't know if that's true. You'd have to ask."

Koeman is taking a strong side to second-tier Rayo, with the Copa del Rey looking likely to be Barca's best chance of winning silverware this season, with Real Madrid and Atletico Madrid both out.

While he may rotate his starting line-up, Koeman expects Lionel Messi to be raring to go after missing two games through suspension.

"It depends on the state of the players. If there are tired boys, we'll have to change," he said.

"We'll take a strong team to get through this tie. We know the road is shorter to winning something. The teams who are left are strong and we saw that in the Supercopa de Espana.

"[Messi] is really looking forward to playing and winning things. He's a winning player who wants titles. We have to wait until the morning to know if he'll play.

"To win something, we need Messi fit."

Barcelona win every time Lionel Messi does not play as they "draw on other strengths", claims former Argentina goalkeeper Hugo Orlando Gatti.

Messi served the final match of a two-game suspension after his red card in the Supercopa de Espana decider as third-placed Barca defeated Elche 2-0 in LaLiga on Sunday.

The record six-time Ballon d'Or winner has been heavily linked with an exit on a free transfer amid interest from Paris Saint-Germain and Manchester City.

Barca have won 10 of 17 games with Messi in LaLiga this season, and one of two in his absence – drawing the other.

Last season, Barca had a 66.7 winning percentage with Messi in the league – claiming 22 of 33 matches, while the Spanish giants won 60.0 per cent of their fixtures in his absence – three wins from five matchups.

But countryman Gatti, no stranger to hitting out at Argentina skipper Messi, told El Chiringuito: "Every time Messi doesn't play, Barcelona win because they can draw on other strengths.

"Football is about winning and if you play well, even better.

"Every time Messi doesn't play, Barcelona win."

Messi – out of contract at season's end – has scored 11 goals in 17 league appearances for Barca this season, while he has 14 across all competitions.

Ronald Koeman's Barca are 10 points adrift of LaLiga leaders Atletico Madrid through 19 rounds in 2020-21.

Barca face Rayo Vallecano in the Copa del Rey round of 16 on Wednesday.

If Paris Saint-Germain have their way, Lionel Messi will be playing for the French giants in 2021-22.

But will he be playing alongside Kylian Mbappe in Paris?

Real Madrid target Mbappe could stay.

TOP STORY – MESSI IN, MBAPPE OUT?

Paris Saint-Germain want to sign Lionel Messi but Kylian Mbappe could remain with the Ligue 1 champions, according to reports.

Barcelona captain Messi is out of contract at season's end and has been heavily linked with PSG and Manchester City.

Le Parisien says there is no doubt who will replace Mbappe at PSG if he departs for LaLiga champions Real Madrid, though Canal + journalist Pierre Menes claims the French forward is interested in staying at Parc des Princes.

ROUND-UP

-  Madrid are considering a €45million (£39.9m) bid to re-sign Sergio Reguilon from Tottenham, according to Sport. Reguilon left the LaLiga champions at the start of the season, but Madrid have an option to buy him back within two years.

- Calciomercato says Juventus are eyeing Bayern Munich duo Corentin Tolisso and Joshua Zirkzee. Bayern are reportedly unwilling to let Zirkzee leave permanently.

- Sport 1 claims Borussia Dortmund are set to battle German rivals Bayern for Borussia Monchengladbach star Florian Neuhaus. The 23-year-old reportedly has a €40m release clause.

- RB Leipzig attacker Hwang Hee-chan could be loaned out amid links to West Ham, reports Kicker.

- Inter and Lautaro Martinez remain in negotiations over a new contract, reports Calciomercato. Once tipped to join Barca, Martinez's Camp Nou dream appears to be fading due to the economic situation caused by the coronavirus pandemic. Inter are not prepared to meet Martinez's wage demands at the moment.

Paris Saint-Germain midfielder Leandro Paredes said the Ligue 1 champions are working on signing Barcelona captain Lionel Messi.

Messi is out of contract at the end of the season and the six-time Ballon d'Or winner has been heavily linked with PSG and Premier League giants Manchester City.

PSG sporting director Leonardo revealed the French powerhouse – now coached by Mauricio Pochettino – are pursuing Messi, after star and former Barca team-mate Neymar made no secret of his desire to reunite with the Argentina skipper.

Having talked up the possibility of Messi's arrival prior to PSG's 4-0 rout of Montpellier on Friday, countryman Paredes told Corriere dello Sport: "It's up to Leo to come to the club, because PSG are trying to convince him.

"To be able to be coached by a coach from your country and the possibility of playing with Leo is a great opportunity... I hope it happens."

Messi sat out Barcelona's 2-0 LaLiga victory at Elche on Sunday due to his two-game suspension following a red card in the Supercopa de Espana final defeat to Athletic Bilbao.

The 33-year-old has scored 11 goals in 17 league appearances for Barca this season, while he has 14 across all competitions.

PSG, meanwhile, are top of Ligue 1 on goal difference ahead of Lille through 21 rounds.

Lionel Messi will miss Barcelona's LaLiga match at Elche on Sunday after losing his appeal against a two-match ban.

The Argentina star was suspended for his red card in the Supercopa de Espana final defeat to Athletic Bilbao, in which he was sent off for striking Asier Villalibre following a VAR review.

It was the first time in 753 appearances for the club in all competitions that Messi was dismissed.

Barca appealed against the suspension but confirmed on Friday that their efforts had been in vain, meaning Messi will not be available for the game at Estadio Martinez Valero.

The six-time Ballon d'Or winner had already served one match of his ban, having been absent from Thursday's Copa del Rey win at Cornella.

Ousmane Dembele and Martin Braithwaite scored in extra time after Barca missed two penalties against the third-tier side.

Messi will be free to return in next Wednesday's Copa del Rey last-16 clash against Rayo Vallecano, with another meeting with Athletic, this time in LaLiga, to follow on January 31.

Leandro Paredes hopes Lionel Messi can be convinced to leave Barcelona for Paris Saint-Germain.

The Ligue 1 champions' sporting director Leonardo confirmed on Monday that the club are keeping a close eye on Messi's plans.

The six-time Ballon d'Or winner is in the final six months of his contract at Camp Nou and could decide to leave on a free transfer after this season, having failed to engineer an exit in 2020.

Paredes would love his compatriot to move to the Parc des Princes, telling reporters on Thursday: "It's natural to want him on your team. But that will be his decision.

"It's the club's responsibility to try to convince him. I hope we can have him with us. But, I repeat, it's his decision."

Paredes is already enjoying working with another fellow countryman at PSG in the shape of Mauricio Pochettino.

The former Tottenham boss took over from Thomas Tuchel this month and has enjoyed an encouraging start, winning three of his first four games in charge including the Trophee des Champions clash with Marseille last week.

Paredes has sensed a sharpening of effort in training and feels Pochettino has inspired a change in mentality.

"Having a coach of the same nationality helps," he said. "We share the same ideas. We get along well. We have to make the most of that.

"Every coach has his ideas, brings his own energy. The mentality is different for us now. We have new options in the game. There is more intensity in training."

Paredes, who joined from Zenit for a reported €40.2million in January 2019, has established himself as more of a first-team regular at PSG this season.

The 26-year-old has started seven league games this term, just one down on his same tally from 2019-20.

Paredes has the second-highest passing accuracy (91.7 per cent) of any of PSG's midfielders to play in at least seven games this season in all competitions.

He also averages just over two interceptions per 90 minutes, the best rate among his team-mates in his position.

"Getting to a club like PSG is never easy. The first six months were difficult but I feel good today," he said.

"I will stay, I hope, for many years. I'm happy in Paris with these team-mates."
