Barcelona are to appeal to Spain's Administrative Court of Sport (TAD) after head coach Ronald Koeman's touchline ban for Saturday's potential LaLiga title decider with Atletico Madrid was upheld.

Koeman was hit with a two-match suspension after being shown a red card for comments he supposedly made to the fourth official during his side's shock 2-1 home loss to Granada last Thursday.

The 58-year-old sat out Sunday's 3-2 win against Valencia, with assistant coach Alfred Schreuder placed in charge for the win that leaves Barca two points behind leaders Atletico ahead of this weekend's showdown.

Barcelona had hoped to have Koeman back for that massive game at Camp Nou, but it was announced on Wednesday that their appeal was not successful.

However, the Catalan giants will now take their case to TAD and have requested a temporary suspension of the ban which will allow the Dutchman to be on the touchline against Atletico.

Barca are also behind second-placed Real Madrid by virtue of an inferior head-to-head record and face Levante, Celta Vigo and Eibar after the visit of Atleti.

Lionel Messi is to be investigated by the Professional Football League (LFP) following an alleged breach of coronavirus-enforced health protocols.

It was claimed my numerous media outlets that Messi invited team-mates and their respective partners to his home after the 3-2 win over Valencia for a celebratory barbecue.

While it has been seen as another example of Messi seemingly being happy again in Barcelona following his attempt to leave last year, the apparent gathering has also attracted the wrong sort of publicity.

Local government has imposed restrictions that prohibit gatherings of more than six people.

"Meetings and/or family and social gatherings, both in the public and private spheres, are allowed as long as the maximum number of six people is not exceeded, except in the case of cohabitants," Catalan regulations state.

"However, family and social gatherings and/or encounters that take place in closed spaces, including homes, are recommended to be restricted as much as possible and limited to visits to dependent or vulnerable people and that are always from the same bubble of coexistence."

Stats Perform News understands LFP is looking into the allegations against Messi in an attempt to understand whether protocols have been violated.

ABC in Spain reports Barca have dismissed the idea of a violation breach due to the fact all the players work in the same bubble every day.

Erling Haaland and Romelu Lukaku appear to be the top forwards on English clubs' shopping lists this off-season.

But Bayern Munich forward Robert Lewandowski may enter the frame amid rumours about his future.

Manchester City and Chelsea are known to be eager to bolster their attacking options and have the funds to finance a major move.

TOP STORY – ENGLAND ON LEWANDOWSKI'S RADAR

SportBild reports that Robert Lewandowski's likely next destination will be the English Premier League, if Bayern Munich opt to sell their Polish forward.

The report claims that Lewandowski's agent Pini Zahavi is trying to put pressure on Bayern for a lucrative contract extension or to sell him to one of England's financially powerful clubs.

Lewandowski still has two years to run on his Bayern contract and the Bavarians are believed to not be ready to negotiate.

ROUND-UP

- Fabrizio Romano claims that Romelu Lukaku is not planning to leave Inter amid interest from Manchester City, Chelsea, Real Madrid and Barcelona, pointing to comments he made following the club's Serie A title triumph on Sunday.

- Romano also claims that Watford, who have won promotion to the Premier League, have begun talks with Inter's Ashley Young who may be available as a free agent.

- Marca reports that PSG are increasingly concerned that Neymar will not sign a contract extension with the club amid talk of a Barcelona move.

- Celtic defender Kristoffer Ajer is being tracked by Premier League club Newcastle United, claims the Daily Record.

- Tottenham are interested in Brazilian teenager Rodrigo Varanda who is currently with Corinthians, says The Sun.

Lionel Messi scored the 50th free-kick goal of his Barcelona career to fuel hopes of a stunning LaLiga title triumph.

Messi's two goals in a 3-2 victory at Valencia on Sunday took him to 28 league strikes for the season, and that also meant the record six-time Ballon d'Or winner stayed ahead of Cristiano Ronaldo in their friendly long-distance rivalry.

Barca captain Messi's seasonal tally is one more than Juventus' former Real Madrid talisman Ronaldo has managed in the current Serie A campaign, after the Portuguese netted twice in a win at Udinese earlier on Sunday.

Both are leading the way in their respective leagues, and only 36-goal Bayern Munich forward Robert Lewandowski has scored more times than Messi in the top five European leagues in the current campaign.

Of Messi's stunning set-piece career haul, 39 of his free-kicks have come in LaLiga but few will have been as important as the curling strike that ultimately made sure of the points at Mestalla, giving Barcelona a 3-1 lead that was trimmed when Carlos Soler hit an excellent consolation.

Barcelona head coach Ronald Koeman was a free-kick specialist himself, but he was absent from the touchline against Valencia.

That was because Koeman received a two-match touchline ban for the remonstrations during Thursday's shock defeat to Granada that saw him sent off.

In his place, Koeman's assistant Alfred Schreuder led the team, and it was down to the former Hoffenheim boss to dampen down excitement about this coming Saturday's clash between Barcelona and current leaders Atletico Madrid at Camp Nou.

Barcelona would go top of LaLiga by one point, for a little over 24 hours at least, should they win that game.

There are just four rounds of fixtures to come, and next week's games appear highly significant, given Real Madrid and Sevilla, the other two teams in title contention, also go head-to-head.

"We are all close," said Schreuder. "But we are there. We don't look at other teams, only at ourselves. Next week isn't a final, we have four matchdays in which we have to try to win.

"Yes, we trust our players to win LaLiga. We have reduced the gap to Atletico since January. We have competed well in these last three months."

The loss to Granada was a juddering result for Barcelona, but they had enough to fend off Valencia.

Messi missed a penalty but scored seconds later as the ball pinged around the Valencia 18-yard box, while Antoine Griezmann was also on target as Barcelona reacted positively to going behind early in the second half.

"We have shown character," Schreuder said. "We believed in what we were doing."

Gerard Pique predicted there will be major twists to come in LaLiga's title race after Barcelona beat Valencia 3-2 to crank up the pressure on Real Madrid and Atletico Madrid.

The Barcelona defensive stalwart said there is a determination within Ronald Koeman's squad to secure a league and cup double after already securing the Copa del Rey title.

Pique believes that would be a major statement by the current set of players, but it will take a big effort from Barcelona, who must face leaders Atletico at Camp Nou this coming Saturday.

Atletico hold a two-point advantage over Barcelona going into that game, while Real Madrid are also two points back from their city rivals. Sevilla, too, are clinging to the hope of fighting their way past the big three to snatch only their second Spanish league title. Sevilla and Madrid face each other next Sunday.

"We hope to be leaders after the next match day, but even if we are leaders, I would not put my hand in the fire that whoever comes out leader will win LaLiga," Pique told Movistar Plus.

He added: "It is not in our hands, but I think that if we win the four games that remain, we have many chances to win LaLiga. It would be a shame if after the effort we made in this second half of the season we wouldn't end up fighting for LaLiga until the end."

Lionel Messi's double strike took his haul to 28 goals in LaLiga this season, and it came despite him missing a penalty when Barcelona were 1-0 behind, just as he also did in the home game against Valencia in December.

As in that first match, Messi made amends by finding the net just seconds after failing from the spot.

Whereas Barcelona could only draw 2-2 at Camp Nou, in this Mestalla clash Messi's equaliser was the cue for a flurry of goals for the Blaugrana, with Antoine Griezmann prodding them ahead. Messi curled a stunning free-kick in off the right post to make it 3-1, before Carlos Soler hit a brilliant consolation for Valencia.

Messi's second goal was the 50th direct free-kick he has scored in his Barcelona career, with 39 of those coming in LaLiga, five in the Champions League, three in the Copa del Rey, two in the UEFA Super Cup and one in the Supercopa de Espana.

The penalty miss, meanwhile, signalled the first time that Messi has missed consecutive spot-kicks for Barcelona in all competitions, after previously failing to convert against Paris Saint-Germain in the Champions League.

Pique acknowledged Barcelona "had to suffer a little" after Soler's strike ramped up the pressure in the closing minutes.

Pique added: "We've shown ourselves and our fans that we want this league title. Winning the Copa was a first step, but we now want LaLiga. It would be a great message for this season and next season."

Barcelona withstood a scare to beat Valencia 3-2 and set up a grandstand Camp Nou clash with LaLiga leaders Atletico Madrid next weekend.

Lionel Messi missed a penalty but scored twice, including a sublime free-kick, with Antoine Griezmann also on target at Mestalla.

The Barcelona goals came after the jolt of conceding early in the second half when Gabriel Paulista headed in from a corner to give the hosts the lead, with visiting boss Ronald Koeman banned from the touchline after his dismissal in the shock defeat to Granada.

Carlos Soler drove in a spectacular late second for Valencia, but Barcelona's success means they are back to just two points behind Atletico, and level again with Real Madrid, as the saga of the title race heads for a thrilling conclusion.

Pedri wasted a great chance in the third minute as he shot wide of the right post after being teed up by Frenkie de Jong, and Ronald Araujo's effort on the stretch from a teasing Messi free-kick was blocked away by goalkeeper Jasper Cillessen.

Valencia's Goncalo Guedes should have scored early in the second half but allowed Marc-Andre ter Stegen to push his shot wide for a corner. However, Gabriel made no mistake when Soler swept the set-piece delivery across from the left, heading in at the far post.

Barcelona drew level in the 57th minute through Messi, despite him failing from the spot. Toni Lato conceded the spot-kick after jabbing his right arm at a floated Messi pass, and although the Argentinian saw his tame penalty parried by Cillessen, Pedri's shot as the ball pinged around the box was deflected to Barcelona's record scorer, who netted from close range.

The visitors went ahead six minutes later when De Jong's powerful header from Jordi Alba's cross was well saved by Cillessen but palmed only as far as Griezmann, who tucked home.

Messi's second goal was a 69th-minute curling free-kick from a central starting point that found the back of the net via the inside of the right post, giving the goalkeeper little chance, a speciality of Barca's captain.

It was arguably topped by Soler's brilliant long-range finish in the 83rd minute, but Valencia could not find a leveller.

Will Lionel Messi stay or leave?

The superstar Barcelona captain is set to become a free agent, though the LaLiga giants are determined to re-sign Messi.

Paris Saint-Germain are interested but Messi could reportedly extend his Camp Nou career.

TOP STORY – MESSI SET FOR BARCA STAY?

Lionel Messi is closer to staying at Barcelona than joining Paris Saint-Germain, according to L'Equipe.

Messi's future has dominated headlines, with his contract due to expire at season's end amid interest from Paris Saint-Germain and Manchester City.

Barca are keen to re-sign Messi, who is encouraged by the Copa del Rey triumph and Joan Laporta's plans, despite an offer from PSG.

ROUND-UP

- Barca have reached out to PSG regarding a possible reunion with Neymar, however, RAC1 says the Ligue 1 holders are not willing to sell the Brazilian superstar.

- Everton are plotting a bid for soon-to-be free agent and City star Sergio Aguero, reports the Daily Star. Aguero will leave the Etihad Stadium on a free transfer and the forward has been linked with Chelsea, Barcelona, Inter and Tottenham.

- Fabrizio Romano says Leicester City are working on a deal to sign Lille star Boubakary Soumare, who has previously been linked with Manchester United, Tottenham, Inter and Napoli.

- The Sun claims Borussia Dortmund have joined United and PSG in the battle sign Brighton and Hove Albion defender Ben White.

- Sky Sport Italia claims Milan ultras met with star goalkeeper Gianluigi Donnarumma and demanded he sits out the fixture against Serie A rivals Juventus if he does not renew his contract. Donnarumma is set to become a free agent and he is yet to re-sign amid reports he is in talks with Juve. The Italy international has also been linked with United, Chelsea and PSG.

- United are prepared to sell Paul Pogba if he does not commit to a new contract, according to The Sun. Juve and Real Madrid are reportedly eyeing the French star. It comes as The Sun also claims United are not willing to part ways with Donny van de Beek following a difficult first season at Old Trafford.

Real Madrid would find the money to buy Erling Haaland at the end of the season if he can be prised away from Borussia Dortmund, according to the player's agent.

Mino Raiola, who represents the Norwegian striker, believes the opportunity to land a rare talent such as Haaland would be too good for Madrid, or Barcelona, to refuse.

Both Spanish giants signed up to the European Super League, a competition that could have helped ease their financial worries.

The apparent collapse of that league led Real Madrid president Florentino Perez to state his club – or any other for that matter – would be unable to afford any spectacular summer signings.

Paris Saint-Germain's Kylian Mbappe has also been linked with a move to Madrid.

Raiola thinks Los Blancos would not back away if Haaland became available.

"I don't know if they can afford him, because I haven't studied their books. But I think they can. I think they all can," Raiola told Spanish newspaper AS. "The question is different: Can Madrid afford not to buy Haaland? And Barca?"

He added: "This change Madrid will carry out needs to last 10 years, and that's why Haaland is important, because he's really young, but you would be buying a youngster with elite experience.

"The same with Mbappe. But you only get one chance to buy them. Right now you have the chance to buy them for the next 10 years. The same happened with Cristiano [Ronaldo] and [Lionel] Messi. Then, once they are in a big team, they don't let them go."

Dortmund have said they do not want to sell their star striker, who turns 21 in July, during the European summer transfer window, and Raiola said of that stance: "Now let's see if that desire is still there through to the 1st of September."

He added: "Today, the official stance of Dortmund is this. But I've got another view, I think that if a good opportunity comes up and everyone would be happy, we'll put it on the table."

Raiola spoke of working towards being able to "create a menu" of options for Haaland, but stressed that was not yet a possibility, and said there would be a risk element whether the player stayed or left Dortmund.

Dortmund have been well off the pace in the Bundesliga this season, currently sitting in fifth place and 16 points adrift of leaders Bayern Munich.

Raiola made it clear that Haaland wants to be a serial trophy winner as well as a prolific scorer. The latter aspect was described by Raiola as the striker's "obsession".

"No doubt he'll pick somewhere where he feels those two things go together best for him," Raiola said.

"It's really hard to lie. When a club like Barcelona or Real Madrid comes in for you, with so much history and being such a big club, it's hard to say no."

Raiola also teased the possibility of Haaland and Mbappe one day featuring alongside one another, saying: "In the big clubs, you can have great players together: Neymar and Messi have been together, Ronaldinho was with great players, Haaland could be alongside Mbappe or not. Great players always play together."

For now, it appears a distant prospect, as Madrid and Barcelona, both hit hard by the COVID-19 crisis, weigh up the pros and cons of just one major transfer market splash.

Ronald Koeman remains convinced Barcelona can still win LaLiga, even though they have left themselves with little margin for error during the run-in.

Barca missed the chance to take over at the top of the table on Thursday, letting slip a one-goal lead to surprisingly lose 2-1 at home to Granada.

The unexpected defeat means Koeman's side instead sit third with just five games to play in the top-flight campaign, starting with Sunday's tricky trip to Valencia.

Yet with Atleti still to visit Camp Nou, a defiant Koeman insists maximum points will be enough to pip both Diego Simeone's side and Real Madrid, who are second in the standings, to the title.

"It is true that we were very disappointed because it was a very great opportunity to get to the top, but there is no more time to be sad because we are fighting with the top three teams," Koeman told the media on Saturday.

"In all the games we have a lot of possession, we create opportunities. It is true that defensively we have to improve things.

"We expect a difficult game [against Valencia], where we are going to have a lot of possession, we have to create, be better defensively.

"It is a great opportunity that we have missed, but I am convinced that if we win the last five games we will be champions."

Sevilla are also firmly in the title race too, sitting just a point behind Barca, while Granada's midweek win provided a further example of why there are no certainties in a highly competitive league, according to Koeman.

"It is a strong championship, with very good teams. There are four teams fighting for LaLiga," he said.

"If you are not well, if you lack things, then you pay dearly. That is the beauty of this season. There is no team superior to the rest. That shows that it is a very strong championship."

Koeman was sent off after Granada's equaliser and is set to serve a two-game touchline ban, though Barcelona have appealed against the punishment.

The Dutchman will watch on from the stands for the game against Valencia, but a reduced suspension would allow him to be back in the technical area for the crucial clash with Atleti on May 8.

"We are going to appeal because I think it is a very exaggerated sanction for saying 'what a character', you wear two games, if you really insult, they give you 20 games," Koeman said. 

"Tomorrow I will not be able to be on the bench, but we have technical staff and we are going to overcome it."

Erling Haaland is hot property right now with a long list of suitors keen on the Norwegian forward.

Financially powerful clubs Real Madrid, Manchester City and Chelsea are among those jostling for the Borussia Dortmund man but Barcelona are in contention too.

Haaland and his agent Mino Raiola visited Barcelona along with Madrid in April as talks commenced.

TOP STORY - MESSI PAY CUT TO FUND HAALAND DEAL

Six-time Ballon d'Or winner Lionel Messi is willing to take a pay cut in order to help Barcelona land Erling Haaland according to Eurosport.

Messi wants to renew with Barca under the assumption the club is ambitious and contending for top honours.

Contract talks have commenced between Messi and the Catalans, with reports that they will offer Messi a new 10-year contract.

ROUND-UP

- Marca reports that Real Madrid are looking to extend Lucas Vazquez's contract with a new and improved offer.

- Raheem Sterling could be offloaded by Manchester City this off-season, in order to fund moves for Erling Haaland and Jack Grealish, claims Football Insider.

- Chelsea are in the race for Juventus' French midfielder Adrien Rabiot, along with Barcelona, reports Calciomercato.

- Gazzetta dello Sport claims that Napoli have made a €10 million offer to Club Brugge for 20-year-old Belgium international Charles De Ketelaere.

- Gazzetta dello Sport also reports that Juventus wants to lure Massimiliano Allegri back to the club to replace head coach Andrea Pirlo.

Barcelona have launched an appeal against the two-match touchline ban handed to Ronald Koeman following his dismissal during the shock 2-1 LaLiga loss to Granada.

Koeman was shown a red card for comments he supposedly made to the fourth official not long after Granada had drawn level at Camp Nou on Thursday.

The Dutchman then watched on from the stands as the home side conceded again in the 79th minute, substitute Jorge Molina heading home to provide a further twist in the title race.

"I don't understand why they have sent me off. They [said I] have disrespected the fourth official," Koeman said after Thursday's match, according to Marca.

"I don't understand the red. According to the delegate, it was a lack of respect for the fourth official. I haven't said anything. I haven't insulted him or anything. But hey, if the fourth official wants to be the star of the night ... thank you."

Barcelona had appeared set to take over at the top of the table but now sit two points behind LaLiga leaders Atletico Madrid with five games remaining.

One of those matches sees Barca host Atleti on May 8, which will be covered by Koeman's suspension unless his appeal is successful. The other fixture will be Sunday's trip to Valencia.

In confirming the appeal, the club referenced that their head coach had not previously been sent off since taking charge.

Meanwhile, Barca have extended Oscar Mingueza's contract.

The defender, who made his first-team debut in a Champions League fixture against Dynamo Kiev in November, is now tied down until June 2023 with a release clause of €100million.

"It's a dream come true. I've been working for many years for this objective, to sign a contract with the first team," Mingueza said in an official club interview.

"I'm really happy, really proud to have this chance after all the support that I have received."

Mingueza has made 36 appearances in all competitions this season since his promotion from the B team.  

If LaLiga's title race wasn't tantalising enough already, Barcelona's shock defeat to Granada on Thursday really threw a spanner in the works.

It looks set to be the most gripping end to any of the top five European leagues this term, and almost certainly the least predictable finish to LaLiga since 2006-07.

Back then there were three teams in with a chance of taking home the title on the final day of the season – Real Madrid and Barcelona, of course, plus Juande Ramos' Sevilla.

As it was, Madrid and Barca won on the last day whereas Sevilla – who needed a win and for the other two to lose – lost at home to Villarreal.

Madrid finished top by virtue of a better head-to-head record over Barca, who were essentially denied the title by their local rivals Espanyol, slumping to a 2-2 draw with them on the penultimate day to hand Los Blancos the initiative.

For the first time since then, Sevilla are again in with a shout of upsetting established order, though on this occasion Atletico Madrid are in the mix as well.

In fact, with just three points separating first from fourth with five games left, it's the closest title race LaLiga has ever seen in a 20-team campaign (1987-1995, 1997-present).

Diego Simeone's side looked certainties for the title not too long ago: at the start of February, they were 11 points clear, but they've won only six of their 14 league games since, including a defeat to Sevilla in early April.

Yet, remarkably, it's still in Atletico's hands thanks to Barca's surprise loss at home to Granada on Thursday.

What made that defeat even more incredible was the fact Granada had just 18 per cent of the ball and scored twice from an xG (expected goals) value of just 0.69. This means they netted more than two times as many as they should have, which speaks to how stunningly clinical they were.

Interestingly – or, infuriatingly, if you're a fan – it was Barcelona's second-highest share of the ball in a league game this season, behind only 82.1 per cent against Cadiz. They lost both games.

It's all shaping up for potentially decisive blows to be struck across May 8 and 9, when the top four all play each other – Barca host Atletico on the Saturday, with Sevilla going to Madrid the next day.

But what does our prediction model say about the most likely outcome in the title race?

How does the predictor work?

The data model estimates the probability of each match outcome – either a win, draw or loss – based on each team's attacking and defensive quality. Those ratings are allocated based on four years' worth of comprehensive historic data points and results, with more weighting given to recent matches to account for improvements or declines in form and performance trends.

The AI simulation takes into account the quality of the opposition that a team scores or concedes goals against and rewards them accordingly. All that data is used to simulate upcoming matches using goal predictions from the Poisson distribution – a detailed mathematical model – with the two teams' attacking and defending ratings used as inputs.

The outcome of the season is then simulated on 10,000 different occasions in order to generate the most accurate possible percentage chance of each team finishing in their ultimate league position.

Without further ado, let's have a good look at the results of the simulation with the predicted final league table…

Atletico take the crown

There we have it… The AI predictor still sees Atletico as the likely champions, with a 38 per cent probability.

It essentially looks like it will come down to their showdown with Barca next Saturday. Atletico hold a slight advantage having beaten Barcelona 1-0 in Madrid earlier this season, and our predictor seemingly doesn't expect Ronald Koeman's men to overturn that at Camp Nou, as the model sees Atletico winning the title by virtue of their head-to-head record.

Nevertheless, Barcelona's outlook is almost identical to just a few weeks ago when the data suggested they had a 32.8 per cent chance, that now dropping ever so slightly to 32.6 – but you can't help but wonder what it would have been had they beaten Granada.

Madrid have drawn two of their previous three games 0-0, and so their chances have dropped from 34.4 per cent to a 26.6 per cent likelihood of winning the title.

Sevilla, perhaps unsurprisingly, remain the outsiders and our prediction model still only gives them a 2.8 per cent probability of winning their first league title since 1946.

However, that's 28 times more likely than just 18 days ago when the data gave them a 0.1 per cent chance of finishing top.

Everything seemingly hinges on next weekend…

Everton have been busy in the transfer market in recent times and they are preparing for another splash.

The Toffees, who are led by two-time Champions League winner Carlo Ancelotti, brought in James Rodriguez, Abdoulaye Doucoure and Allan this season.

Everton remain in the hunt for European football with a top 10 finish looking assured but owner Farhad Moshiri's ambition still burns for more.

TOP STORY - EVERTON SET FOR COUTINHO SPLASH

Everton are set to land former Liverpool forward Philippe Coutinho from Barcelona in a £35million deal, according to The Sun.

The Toffees are allegedly already house hunting for the 28-year-old Brazilian, who would join countrymen Richarlison, Bernard and Allan at Goodison Park.

Coutinho has never quite settled at Barcelona since leaving Liverpool for Camp Nou in 2018, spending time on loan on Bayern Munich, while he has had injuries this term.

Barcelona are reportedly keen to offload Coutinho, who underwent knee surgery earlier this month, even for a cut-price fee.

ROUND-UP

- Calciomercato claims that Inter have rebuffed Manchester City's advances for Romelu Lukaku, insisting they are not willing to listen to any offers for the Belgian marksman.

- Aston Villa are monitoring Tammy Abraham's situation at Chelsea after it emerged that Blues are willing to sell him for a reported £40 million price tag, claims The Mirror.

- The Sun reports Brighton's Ben White has attracted interest from Borussia Dortmund who join the likes of Manchester United, Paris Saint-Germain and Arsenal in pursuing him.

- Tottenham are hoping to speak to Ajax coach Erik ten Hag about taking up their vacant position following Jose Mourinho's sacking, according to The Guardian.

Ronald Koeman suggested the fourth official perhaps wanted to be "the star of the night" after the Barcelona boss was set off in Thursday's damaging 2-1 defeat to Granada.

Talisman Lionel Messi's 23rd-minute goal appeared to have Barca on track towards a fifth straight home win and three points that would have seen them leapfrog rivals Real Madrid and table-toppers Atletico Madrid in LaLiga.

However, Darwin Machis levelled and Koeman was sent to the stands prior to Jorge Molina heading home the winner 11 minutes from time to leave Barca two points off the pace with five games to play.

Koeman insisted he did not say anything insulting to the official and hinted he may challenge the decision.

"I don't understand why they have sent me off. They [said I] have disrespected the fourth official," he said in quotes reported by Marca.

"I don't understand the red. According to the delegate, it was a lack of respect for the fourth official. 

"I haven't said anything. I haven't insulted him or anything. But hey, if the fourth official wants to be the star of the night ... thank you.

"Let's see what the record says. If the record says something that I haven't said, I'll have to do something."

Koeman accepted his team made errors in a defeat few would have seen coming but the Dutchman is refusing to lose belief in a thrilling title tussle.

"We lost focus in the second half and made mistakes in defence," he added.

"We must accept today's defeat. It is reality. We had opportunities to win, but okay we have five games to go. Each one will have its difficulties. We have to prepare well for next Sunday.

"There are still possibilities. We have to accept defeat, analyse it and prepare for this tournament.

"I think we have tried to continue. We have not created many opportunities after their goals. They have closed down well and we could not create more.

"Seeing the two goals, we leave spaces where we have to close them. We have not been well defensively.

"It is a hard blow to stop depending on us. We are disappointed. We have five games to be champions. For us it is the same as for others."

Barcelona missed the chance to move top of LaLiga after suffering a shock 2-1 loss to Granada at Camp Nou on Thursday.

Lionel Messi’s 23rd-minute goal appeared to have Barca on course for a fifth straight home win, a result good enough to see them leapfrog both rivals Real Madrid and long-time leaders Atletico in the table.

However, Granada – who had failed to even manage a draw in any of their previous 25 league visits to their Catalan opponents – turned the game around to further change the outlook in the title race.

Darwin Machis equalised before Barca boss Ronald Koeman was shown a red card, meaning the Dutchman had to watch on from the stands as Jorge Molina was afforded time and space to head in a 79th-minute winner.

The dramatic turnaround had never appeared on the cards, yet Barcelona allowed their opponents to score with their only two attempts on target to cause a huge upset.

Messi had broken the deadlock after linking up with Antoine Griezmann, the Frenchman timing his delayed return pass perfectly to allow his team-mate to fizz a low, left-footed shot beyond goalkeeper Aaron Escandell and into the far corner of the net.

However, Messi was not quite so clinical with another one-on-one opportunity later in the first half and Griezmann himself failed to capitalise when presented with a clear sight of goal soon after the break, firing well wide with his right foot.

Sergi Roberto also sent a volley off target as Barca struggled to make their dominance tell – and Granada made them pay to clinch a result that will undoubtedly be celebrated in the Spanish capital.

Oscar Mingueza's failure to cut out a throughball allowed Machis to run clear and slot the ball beyond the advancing Marc-Andre ter Stegen, while Barca's goalkeeper had no chance when Molina ghosted into the penalty area to convert Adrian Marin's cross.
