Barcelona forward Antoine Griezmann labelled Lionel Messi a "legend" after the superstar captain dominated headlines on Sunday.

After details of Messi's Barca contract were reported by El Mundo earlier in the day, the record six-time Ballon d'Or winner scored another landmark goal as the embattled LaLiga giants beat Athletic Bilbao 2-1.

Messi opened the scoring with a 20th-minute free-kick – his 650th goal for Barca – before Jordi Alba's own goal restored parity, though Griezmann secured maximum points 16 minutes from the end.

After El Mundo claimed the deal Messi signed at Camp Nou in 2017 – which expires at the end of the season – is worth more than €555million, Griezmann was asked about the 33-year-old's value.

"We are enjoying Messi, he's a legend," Griezmann told Movistar.

"Hopefully we can keep enjoying him and he can keep helping us win."

Messi – tipped to leave Barca amid strong links to Paris Saint-Germain and Manchester City – has scored two direct free-kick goals from his last four attempts for Barcelona in all competitions, after scoring just one from his previous 62 attempts.

Of Messi's 650 goals for Barcelona, 49 of them have been direct free-kicks – 38 in LaLiga.

Messi has 12 goals and two assists in the league for Barca, who are second and 10 points adrift of leaders Atletico Madrid.

Griezmann's late winner for Barca maintained his superb record against Athletic.

The France international has now been involved in 15 goals against the Basque side (nine goals and six assists), more than he has achieved against any other team in the competition.

Lionel Messi did not deserve his contract to be leaked to a newspaper, said Ronald Koeman, as the Barcelona head coach claimed there was an agenda to "hurt" the Argentine superstar.

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.

It was already believed that Messi was on an extraordinary salary at Barcelona, given he is recognised by many as the greatest current player of the world's most popular sport.

The leaking of the exact sums payable to Messi has caused a stir, coming at a time when embattled LaLiga giants Barcelona are reported to have built up debts of over €1billion.

Koeman rejected any suggestion that Messi's contract is in any way connected to Barcelona facing a financial hurdle, insisting he has "helped this club to make it very great".

The club's record scorer, who netted his 650th Barcelona goal in Sunday's 2-1 win over Athletic Bilbao, could leave on a free transfer in a matter of months.

And Koeman vowed that if anyone employed by Barcelona was proven to have leaked private details, they would be shown the door.

"If you are part of the club, you have to help the club, the coaches, the players. If someone from the club has leaked this, they cannot have a future at this club," Koeman said.

"They are things that come out, that cannot come out. There are people who are interested in hurting Messi and Barca."

Messi is sure to have been unimpressed by his personal details making it into the public domain, but the record six-time Ballon d'Or winner did not let it impede his performance on the pitch against Athletic.

Speaking after the game, Koeman expressed alarm that anyone would want to cause upset in the ranks, particularly concerning Messi, a player destined to be remembered as an all-time great.

"You have to respect him, I see bad intention and desire to hurt," Koeman said, quoted by Mundo Deportivo.

"We must try to find out how this could have come out in the press and we have to focus on our work, that the team are well, and we cannot allow ourselves to lose focus over this issue."

Ronald Koeman said Barcelona "can't aspire to much" without Lionel Messi after the Argentinian scored another landmark goal in Sunday's 2-1 win over Athletic Bilbao.

Messi was headline news earlier in the day when a report by El Mundo claimed the deal he signed at Camp Nou in 2017, which expires at the end of this season, is worth more than €555million.

He proved his worth to Barca with a fine free-kick midway through the first half - his 650th goal for the club - before Jordi Alba's own goal drew Athletic level early in the second half.

Antoine Griezmann secured all three points with the winner 16 minutes from time, though, to help Barca leapfrog Sevilla and Real Madrid into second in LaLiga, 10 points behind leaders Atletico Madrid.

Head coach Koeman was less than impressed with the details of Messi's contract surfacing, but insists the saga did not provide any additional motivation for a player he believes is the world's best.

"We've known, for quite some time, that he's the best in the world," the former Netherlands coach told Movistar Plus.

"He's done a lot for the club. He's decisive during games. You have to respect everything he's done. He's a great player, he gives us creativity in attack. Without Leo, you can't aspire to much."

Koeman added, according to Marca: "He hasn't been more motivated today [because of the reports]. What's happened has been for bad intentions, to cause harm.

"We have to be united and focused. Things that are published have to be put to the side, but it's tough."

It seems unlikely that Barca will rein in Atletico, who can move 13 points clear if they win their game in hand, but Koeman says his improving side have no intention of giving up hope of claiming the title.

"The team is improving," Koeman added. "There's concentration, mentality. I'm not saying we didn't have that before, but we're growing in confidence.

"It's important to be second. We want to be as high as possible. The gap to the leaders is big but we have to keep going."

Griezmann's late winner maintained his superb record against Athletic.

The France international has now been involved in 15 goals against the Basque side (nine goals and six assists), more than he has achieved against any other team in the competition.

The former Atletico Madrid forward was pleased to overcome an obdurate opponent and had words of praise for Ousmane Dembele, whose fine pass played in Oscar Mingueza in the build-up to the winning goal.

Griezmann told Movistar Plus: "Sometimes you play and sometimes you don't but in the end we are all part of this and we need everyone. Ousmane is playing very well, he is taking good care of himself and we try to ensure that he is in the best condition."

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.

Ronald Araujo says he is inspired by Gerard Pique as he bids to carve out a lasting career at Barcelona. 

The 21-year-old Uruguayan has played in 10 LaLiga games already this season after featuring in just six during his debut campaign for the Catalan giants in 2019-20. 

In those appearances he has completed eight blocks – three more than any other Barca player – made the second highest number of clearances (29) and has yet to be dribbled past by an opponent. 

His displays have earned him comparisons with club icon Pique and Araujo admits he looks to the 33-year-old, who has made 553 appearances for Barca, for inspiration. 

"His experience has always been one thing that I have looked at since I arrived and more now that I share a dressing room with him," he told Mundo Deportivo. 

"I like to look at the characteristics of each player but from Gerard I like to look at how he plays with the ball, which is something that I felt was missing from my play, and also that he is a defender who is not very fast but is always well positioned. 

"I pay attention to that a lot. Every day I try to get a little information out of him in every game and in every training session."

Araujo also praised the influence of goalkeeper Marc-Andre ter Stegen, adding: "Marc speaks to me a lot, how to position myself or have peace of mind to play with the ball.

"Marc is very important and I always emphasise that he is always talking to us and is very important to us. 

"When he gives us the ball he already tells us where the opponent is coming from because he is looking straight ahead and these are very important references for us."

Araujo joined from Uruguayan side Boston River in August 2018 and is already thinking about spending the next decade at a club that has made a significant impact on him.  

"I work to be able to be here for many years, it is one of my goals and something that I would like," he said. 

"I really like Barca and everything that Barca is and I want to be here for many years. If there is the possibility of being here for 10 years I would be very happy. And then the rest, one day being a captain or whatever, that will come by itself. 

"The important thing is to continue being me and doing what I do every game and every training session and helping the team because it is my way of helping us to be connected and I myself feel connected when I am talking all the time. I can concentrate and I know that I help my colleagues."

Ronald Koeman's Barca, who are 10 points adrift of LaLiga leaders Atletico Madrid, take on Athletic Bilbao on Sunday.

Luis Suarez is "blowing up LaLiga" to prove to Barcelona that he is not finished, according to Gustavo Poyet.

Barca made the decision to allow Suarez to leave in the close-season after a successful six-year stay at Camp Nou.

Domestic rivals Atletico Madrid moved swiftly to sign him on a two-year contract in September and have reaped the rewards.

Uruguay international Suarez has scored 12 goals in 15 league games, adding two assists, and his side sat seven points clear at the top of the table heading into the weekend's top-flight action.

His compatriot Poyet, who formerly starred with Real Zaragoza, Chelsea and Tottenham, believes Suarez has been desperate to show he is not past his best, having turned 34 this month.

Discussing why he thinks Atletico are title favourites, Poyet told Stats Perform News: "They took a very important decision which would not be easy for some people.

"It was easy for El Cholo [head coach Diego Simeone], from what I know of him.

"Bringing in Luis Suarez as Barcelona didn't want him, bring him in now. And Luis went with his mentality, 'I will show you who I am'.

"A bit like a Uruguayan I am, 'You don't want me? Am I over? Let’s see!'. 

"And this is blowing up LaLiga."

Leaving Barcelona gave Suarez the push he needed to make changes and give something extra, in the view of Poyet.

He added: "What it shows is that sometimes football players need something different, just something.

"It can be a different treatment or being tougher [on them]. But they need something to react to.

"He was low, not bad, but like the [Barcelona] team, he was low. He needed a new challenge and sometimes it is tough to get it in the same club.

"It can happen with arrival of a new manager, or signing a new player who becomes a rival of yours. There are different ways, but if it does not happen, it looks difficult.

"However, there is no doubt that joining such a special team like Atletico with such a special coach, similar character [to Suarez], you get it and he is showing that extra [effort] needed.

"Sometimes we all need to realise. Get out from the club and notice that you have to do something to change the situation.

"I was not doubtful on his performance, especially playing in that system and having that responsibility.

"I don't forget it that it was him or Diego Costa [playing] at the beginning, sometimes both together. But at the time, Costa had gone, with all the respect to other players, it was only Luis Suarez.

"That also gives him the responsibility on scoring 20 to 30 goals and Luis accepts it in a natural way."

Atletico play away to Cadiz on Sunday and Poyet was asked if he thinks they can finish the job and win the title in the second half of the season.

"I do, for two reasons," he replied. "First, they are very strong, all credit to them, and also, because Real Madrid and Barcelona are currently really poor.

"I don't see any consistency in any of them. Unfortunately, when I look at Barcelona or Real Madrid I don't know what to expect from them, I don't know what is going to happen.

"And that proves it is a year for other teams like Atletico Madrid of El Cholo to go the distance, to actually show they belong at the top without any falling.

"We will see how they can keep it up. We know everything can change with injuries, sending-offs, everything can become really difficult. But no doubts, the main candidate is Atletico Madrid."

Barcelona are not ready to win the biggest trophies and fans must be "realistic" about their title chances, head coach Ronald Koeman said.

The Catalans face Athletic Bilbao on Sunday for the first time since suffering defeat to Marcelino's side in the final of the Supercopa de Espana.

Barca go into the match 10 points behind LaLiga leaders Atletico Madrid, who have a game in hand. Their tally of 37 points from their first 19 matches is their lowest return at this stage of a season since 2003-04.

According to a Stats Perform AI model run last week, Barca had just a 12.4 per cent likelihood of winning LaLiga, with Atletico overwhelming favourites at 75.1 per cent.

Having won just twice in their past seven meetings with Athletic in all competitions, the pressure is on Barca and Koeman to deliver to keep their slim hopes of a title challenge intact.

However, the former Netherlands boss feels this has been a year of transition for the club that means they should not aim too high.

"It's tough, because the points gap is very big," he said on Saturday. "In the Champions League, there's no clear favourite. We have a knockout against Paris Saint-Germain that we'll try to get through.

"I have said several times that this is a season where we are changing things, we are opting for young players.

"Barcelona are not about to win a lot of things right now. We have to be realistic about where we've come from, the changes we've made... not everything depends on one player. We always have to be ready to fight, but we have to be realistic."

With Barca having reported debts of close to €1.2billion and with presidential elections not taking place until March, January signings have been practically impossible.

The club remain hopeful, however, of bringing in Eric Garcia from Manchester City this month. The defender has already agreed to a deal with the club but they are exploring options to sign him in the coming days rather than wait for a free transfer at the end of the season, when his City contract expires.

"It's always important to have someone at the club working to improve our squad, if not in January for next year," Koeman said.

"It doesn't bother me because it's a job the club has to do. The players don't have to be bothered by these issues, because we talk to them every day, they take part in the games.... These things happen at any club in the world and I don't see any problem.

"We'll certainly have him [Garcia] for next season. If it's not possible for him to come now, we have to accept it and we'll keep going with what there is.

"But I don't know. I don't want to spend energy on this and I'm just focused on preparing the team for the games.

"I spoke to [City manager] Pep [Guardiola] a little while ago to wish him a happy 50th birthday. We talked, but we don't do so on Eric Garcia. That's not my job. I'm dedicated to coaching.

"I think it's normal that it's talked about so much because it's a transfer and because of the circumstances around the club. I've said what I thought, but what ends up happening is something I can't control, so I'm focused on what's important, which is trying to win games."

Kylian Mbappe's future continues to dominate headlines.

For so long, Real Madrid have been favourites to prise Mbappe to the Santiago Bernabeu.

But Premier League champions Liverpool are believed to be stepping up their pursuit.

TOP STORY – LIVERPOOL FRONTRUNNERS FOR MBAPPE

Liverpool are ahead of Real Madrid in the race to sign Paris Saint-Germain star Kylian Mbappe , according to Canal+ show Late Football Club.

Mbappe has been tipped to leave Ligue 1 champions PSG for LaLiga holders Madrid at the end of the season.

But Liverpool are reportedly the frontrunners to prise the France World Cup winner to Anfield amid doubts over Mohamed Salah 's future.

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.

Barcelona have been drawn away to Granada in the Copa del Rey quarter-finals.

Ronald Koeman's team fought back to defeat second-tier Rayo Vallecano 2-1 on Wednesday, earning their place in the last eight after a major scare.

Barca will now have to face a LaLiga team in Granada, a side they defeated 4-0 at Los Carmenes earlier this month.  

Sevilla, who have not won the competition since 2010, will play away to Almeria, the last team from outside the top flight left in the tournament.

Real Betis will take on Athletic Bilbao, who are yet to play Real Sociedad in the final of last season's Copa, while the other match will see Levante host Villarreal.

Ties will be played across next week from Tuesday to Thursday, with Barca favourites to win it after Atletico Madrid and Real Madrid were eliminated against lower-league opposition.

Mauricio Pochettino denied he had turned down chances to coach Real Madrid and Barcelona.

Pochettino has been linked with the LaLiga giants previously, although he took over at Paris Saint-Germain at the start of the month.

But Pochettino said reports he had turned down Madrid and Barcelona were untrue.

"This is not the case, although there was a lot of talk at the time," he told Marca.

"We have a lot of respect for the teams that may have been interested in our staff.

"It wasn't like that and of course I have been approached by clubs, but the one we received with love was from PSG. And this is the ideal project."

After spells in charge of Espanyol and Southampton, Pochettino was at the helm of Tottenham for five and a half years before being sacked in November 2019.

He has overseen four wins in five games since taking charge of PSG, who are top of Ligue 1 ahead of visiting Lorient on Sunday.

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."
