Joao Felix has tested positive for COVID-19, adding to Diego Simeone's problems ahead of Atletico Madrid's meeting with Celta Vigo.

Portugal international Joao Felix is self-isolating at home, as team-mates Mario Hermoso and Yannick Carrasco have been doing since Friday.

A brief Atletico statement read: "Joao Felix has tested positive for COVID-19. The striker is isolating at home, in compliance with the health authorities' guidelines and LaLiga protocols."

Simeone's men have a 10-point advantage at the top of LaLiga and welcome Celta to the Wanda Metropolitano on Monday. They then travel to Granada the following Saturday.

Hermoso and Carrasco are unlikely to return for the meeting with Celta, while Kieran Trippier will be absent due to suspension.

Joao Felix marked his return to the starting line-up against Valencia on January 24 by scoring his first goal in almost two months and setting up another, leading Atletico from a goal down to a 3-1 victory.

The 21-year-old has been left out of the first XI eight times in LaLiga this season and Atletico have won all those matches.

However, when Joao Felix starts they average two more shots (12.1 to 10.0) and their goals-per-game ratio improves from 1.9 to 2.3.

Liverpool's need for defensive reinforcements was always likely to dominate the headlines on transfer deadline day and so it proved as the Premier League champions made two late signings.

Centre-back Ben Davies arrived from Preston North End, while Liverpool made a further addition to the heart of their backline with the loan signing of Ozan Kabak from Bundesliga strugglers Schalke until the end of the season.

Those signings came on a day that saw Joel Matip ruled out for the rest of the season with an ankle ligament injury. Virgil van Dijk and Joe Gomez are long-term absentees and Liverpool were forced to play Jordan Henderson and Nathaniel Phillips at centre-back in Sunday's win at West Ham.

Heading for the Anfield exit door is Takumi Minamino, the forward moving to Southampton on a six-month loan deal having only joined Liverpool last January.

It came after Southampton loaned veteran Shane Long to promotion-chasing Championship side Bournemouth.

Bournemouth also sanctioned the departure of Joshua King to Everton for a nominal fee until the end of the season.

There were outgoings at Arsenal as well, with Shkodran Mustafi signing for Schalke on a short-term deal and Joe Willock going on loan to Newcastle United, who let DeAndre Yedlin leave for Galatasaray.

Arsenal also sent Ainsley Maitland-Niles to West Brom on loan.

Turkish giants Galatasaray acquired Gedson Fernandes on a temporary deal from Benfica following an unsuccessful stint at Tottenham.

In Serie A, Parma landed Bayern Munich's teenage forward Joshua Zirkzee in a loan deal that contains the option to sign the 19-year-old permanently.

Atalanta are firmly in contention for a top-four finish in Serie A and bolstered their ranks for that push with the capture of Ukraine midfielder Viktor Kovalenko from Shakhtar Donetsk.

Roma can afford to have hopes of a title challenge and brought in teenage full-back Bryan Reynolds from MLS outfit Dallas on an initial loan deal, with an obligation to buy, to help them.

Frozen out at Juventus, midfielder Sami Khedira is back in the Bundesliga following a switch to Hertha Berlin, but one of European football's most exciting talents is heading to Italy after Udinese signed Jayden Braaf on loan from Manchester City with an option to buy.

Elsewhere, Everton defender Jonjoe Kenny joined Celtic on loan for the rest of the season, Brighton and Hove Albion signed highly rated midfielder Moises Caicedo from Independiente del Valle, West Brom loaned Okay Yokuslu from Celta Vigo and defender Teden Mengi moved from Manchester United to Wayne Rooney's Derby County on a temporary basis.

Even in these extraordinary times, Barcelona letting Luis Suarez go to Atletico Madrid is starting to look like the oddest decision of the season.

Suarez's double over Eibar on Thursday secured a 2-1 victory for the league leaders, who are seven points clear at the top with a game in hand over champions Real Madrid in second.

The Uruguay star, who has netted six in his past six league games for Atleti, is joint-top of the division's scoring charts alongside former team-mate Lionel Messi.

It seems increasingly likely that Suarez, and certainly Atletico, will be at the top of the tree come the end of 2020-21.

With the majority of sides having now played half of their matches, the Stats Perform AI team have run the numbers to simulate how the rest of the LaLiga campaign will play out – and it's good news for Diego Simeone.

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.

ATLETICO WIN AT A CANTER

Atletico have been given a 75.1 per cent chance of winning LaLiga, according to the model.

Simeone's men are predicted to finish on 86 points, nine clear of the rest of the field. They are given just a 17.8 per cent chance of coming second and dropping outside the top four is considered practically impossible.

Barcelona and reigning champions Real Madrid are predicted to end with 77 points apiece, with just a 12.4 per cent chance each of pipping Atleti to the title. Madrid have a 41 per cent chance of finishing second, slightly above Barca's 39.4, having beaten Ronald Koeman's side 3-1 in the first Clasico of the season at Camp Nou last October.

Those two are, at least, very likely to end up in a Champions League place. They are expected to be joined there by Sevilla, who have a 47.8 per cent chance of finishing fourth on 65 points, just three above Villarreal and six clear of Real Sociedad. The remaining European spot is predicted to be a close battle between Granada, Getafe and Real Betis, with Diego Martinez's men odds on to snatch it.

Valencia fans might be enduring a difficult time (again), and our sim has Los Che missing out on European football once more, if only by four points. That said, they still have a 3.6 per cent chance of a Europa League spot, which is better odds than those given to Supercopa de Espana winners Athletic Bilbao.

WOE FOR HUESCA

At the other end of a relatively tight table, in which just 11 points will separate seventh from 16th, it looks like Huesca are in for a tough run-in. They are given a 59.7 per cent chance of finishing bottom of the pile and just a 5.1 per cent shot at avoiding relegation, having won only once so far this term.

Osasuna are predicted to end up just four points above them, with the bottom three likely to be completed by Deportivo Alaves, although Elche will also be right in the mix. In fact, with those two tipped to finish level on 39 points, survival could come down to their head-to-head record, making their showdown on May 11 potentially decisive. Elche have the advantage there, having won the reverse game 2-0 away from home.

Real Valladolid are expected to have just enough to stay out of trouble, although they have scant room for manoeuvre, with our predictor giving them an equal 15.1 per cent chance of finishing 17th and 18th.

Eibar and Cadiz are looking likely to stay safe; indeed, Jose Luis Mendilibar's men, along with Celta Vigo and Athletic, are given a 0.1 per cent chance of gatecrashing the top four. They might well have boosted those odds this week were it not for that pesky Suarez.

Zinedine Zidane has no plans to rest Real Madrid striker Karim Benzema as he vowed slowly ease Eden Hazard back to full match fitness.

Benzema failed to register a single shot on goal in Madrid's 2-0 win over Celta Vigo in LaLiga on Saturday and twice missed the target from good positions.

The 33-year-old has started 15 of Madrid's 17 LaLiga matches this season and only goalkeeper Thibaut Courtois and Raphael Varane have played more minutes.

When asked in a post-match media conference if Benzema, who has scored eight goals in LaLiga, needed a break, following a slightly jaded showing, Zidane disagreed.

"I don’t think he’s tired," Zidane said.

"I think he did well and I took him off so that another player could play. We’re in a great spell. We’re doing the right things and we have to continue like this."

Hazard came off the bench for another run out late in the second half against Celta as he stepped up his return from an injury-hit start to the season.

"We are going to go little by little," added Zidane. "Little by little, you have to recover feelings.

"We have to take it slowly and not force anything. He has to get back to his best and take it slowly. That’s all it is."

Madrid's possession against Celta was 41 per cent which was the lowest recorded in a win under Zidane at home in all competitions.

The Madrid head coach was, however, satisfied with the manner in which his side were able to manage the game against Celta.

"We played a complete game from the beginning to the end," Zidane explained.

"We controlled the game well, we had a good balance, when it came to pressing up and getting the ball back, we did everything well.

"You have to control when the rival team has strong moments in the game, but the feelings are good, out of nine games we won six and three draws."

Goals from Lucas Vazquez and Marco Asensio gave Madrid the victory as the pair assisted each other in what was the fourth duo to combine between them in a single LaLiga game this season.

Zidane added: "I am happy for Asensio. He has had a major injury and now he is much better and improving every time.

"Vazquez is very reliable, very involved and I am happy for what he is doing. We played a very serious game. I'm happy for everyone."

Sergio Ramos has not been named in Real Madrid's squad for their LaLiga match Celta Vigo on Saturday.

The Madrid captain did not train on Friday and, according to Marca, is struggling with a stomach issue.

Ramos, the only unexpected absentee from a 23-man group, has scored twice in 13 league appearances this season.

The centre-back has contributed to five clean sheets, averaging 1.1 tackles, 2.8 clearances, 1.5 interceptions and 0.3 blocks per 90 minutes.

He has made only a single error leading to a shot and received three yellow cards.

Madrid will have to adapt to the absence of the talismanic Ramos, having won just one of the three prior league games he has missed this term.

However, the defending champions are unbeaten in 12 against eighth-placed Celta in LaLiga.

Zinedine Zidane is aiming to "take advantage of the moment" at Real Madrid as he is unsure how long his Santiago Bernabeu reign will last.

The four-year anniversary of Zidane's initial appointment at Madrid is approaching, but the head coach revealed last month he was not discussing an extension to a contract that expires in 2022.

The Frenchman was asked prior to Saturday's game against Celta Vigo if another four years at Madrid - this time unbroken by a spell away - could be on the cards.

However, unable to provide any promises over a long-term stay, Zidane responded: "It takes a lot out of you, but it's a great position here.

"I'm lucky enough to say I'm manager of Real Madrid and take advantage of every moment. I can't say a month, a year or four years. Life is just about the day to day.

"That's what I'm interested in: the day to day, to give everything I can, in every training session, every game. That's what I'm interested in.

"The rest? I don't know what's going to happen in one week. That's why we have to take advantage of the moment."

Zidane will hope to have added to his 11 major honours by the time he does depart, although this season's LaLiga title race is far from straightforward.

Defending champions Madrid can at least briefly move above Atletico Madrid if they beat Celta, against whom they are unbeaten in 12 in LaLiga, but Zidane's men have already played two more games than their city rivals.

It is advantage Atleti for now, yet the former Ballon d'Or winner is not overly concerned.

"Being first means you have an advantage, and that's it," Zidane explained. "We just have to keep on going. We can't control [Atleti being favourites].

"They have an advantage because they're first, and that's it. People are speaking a lot about Atletico now, because, as I said, they're first.

"But the nice thing about this league, right up until the end, it's going to be an open league - as it always is. We'll see."

Despite their strong recent record against Celta - scoring in 28 consecutive home LaLiga meetings, their longest ongoing such run against any side - Madrid were held 2-2 at the Santiago Bernabeu last season.

Eighth-placed Celta could draw against Madrid in consecutive matches for the first time since May 2003.

Zinedine Zidane is not entertaining speculation about transfer talks with David Alaba as Real Madrid battle to defend their LaLiga title.

Bayern Munich defender Alaba is out of contract in Germany at the end of the season and negotiations over an extension have so far proved fruitless for the European champions.

The Austria international has been mooted as a target for Manchester United, Manchester City, Chelsea and Paris Saint-Germain as well as Madrid, although Zidane's outfit are considered favourites for his signature in some quarters.

Alaba was a key part of the Bayern team that won the Champions League last season.

However, since the start of 2019-20, he has committed four errors leading to shots in the competition, a joint-high among defenders. None of these have resulted in goals, while Madrid's Raphael Varane has made the same number of mistakes but been punished on all four occasions.

Alaba's statistics over this period are very similar to Varane's, playing 13 games to his 14 and having 29 fewer touches and seven fewer successful passes.

Varane is also just four tackles, two blocks, five clearances and seven interceptions ahead of his counterpart.

Rather than being signed as a competitor to Varane, though, Alaba could partner the World Cup winner as talismanic Madrid captain Sergio Ramos approaches his 35th birthday.

Either way, the speculation does not interest head coach Zidane, who said ahead of facing Celta Vigo: "We've got all our players here. I'm just thinking about the game tomorrow with the players that I have here.

"Then maybe you're going to ask me about the players that are playing a lot or not playing a lot. We have 22 players, 25 with the goalkeepers, a very big squad.

"We have enough to think about with the games that we have not to be thinking about players that aren't even ours. Please, we're thinking just about the game tomorrow."

While Zidane is keeping his focus on LaLiga, where Madrid trail Atletico Madrid by two points, the need to bring in a player of Alaba's calibre would become urgent if a new contract for Ramos was not agreed.

The PSG-linked skipper, Luka Modric and Lucas Vazquez are all free agents, like Alaba, in June 2021.

"Yes, we all want [contracts to be signed]," Zidane said. "We want the situation to be sorted as quickly as possible.

"It's in everyone's interests, it would be good for everyone, so hopefully it can be sorted out quickly."
