Paris Saint-Germain duo Marco Verratti and Abdou Diallo have tested positive for coronavirus.

The Ligue 1 champions confirmed on Friday that the pair had returned positive PCR tests and will enter self-isolation.

They will subsequently miss Sunday's game at Lorient, with PSG looking to extend their unbeaten run under head coach Mauricio Pochettino to six games.

PSG host Nimes on Wednesday before a trip to the Stade Velodrome to take on arch-rivals Marseille.

Pochettino's men are level on points with Lille at the top of the Ligue 1 table and two clear of Lyon as the nine-time champions face a rate battle to retain the title.

Jamaican players Lamar Walker and Jashaun Anglin have been signed by Miami FC in the United Soccer League, the club announced today.

Andre Villas-Boas expects to leave Marseille at the end of the season after the former Chelsea and Tottenham boss admitted to an "abysmal" failure.

The 43-year-old, who was appointed by OM in May 2019, will see his two-year contract expire at the end of this campaign.

Marseille sit 13 points behind Ligue 1 leaders Paris Saint-Germain heading into the latest round of fixtures, occupying sixth place having lost their last three games in the competition.

Their Champions League performance was also far short of expectations, with Marseille finishing at the foot of their group with just three points.

Asked whether it looked as though he would leave in June, Villas-Boas said on Friday: "Yes, I think so. I don't have other information.

"But I'm not asking for anything, with the position we have, it's rather normal.

"With our performances this year, it's normal. It's true that it goes a bit against what the management said, but yes, I think it'll be the end.

"I think we all agree this is the path it's taking. Before, there was some noise, there were some talks between my agents and the club, now there's nothing."

Villas-Boas had hoped his team would be challenging PSG for the title, but instead they are outside the Europa League qualifying places.

Marseille sold midfielder Morgan Sanson to Aston Villa this week, while young winger Marley Ake left for Juventus and Kevin Strootman was loaned to Genoa.

Such exits may weaken Marseille for the remainder of the season, although they have signed Arkadiusz Milik on loan from Napoli and Franco Tongya arrived from Juventus.

"Guys, look, we're 15 points behind, which is an abysmal gap behind our season goal," Villas-Boas said.

"I'm not going to argue that. I told you that next season is Year Zero for the club, after all has been done, it's going to be deep cleaning.

"And it's good to create a strong base for the future."

Portuguese coach Villas-Boas had his big break when he served on Jose Mourinho's staff at Porto, Chelsea and Inter before striking out on his own.

After spells in Portugal with Academica and Porto, he had stints with Chelsea and Tottenham before moving on to Zenit and Shanghai SIPG, spending 18 months without a club prior to accepting the Marseille job.

Cristiano Ronaldo's behaviour on his days off is not Juventus's responsibility, according to Andrea Pirlo, after the five-time Ballon d'Or winner allegedly broke coronavirus travel restrictions.

Valle d'Aosta police are investigating whether Ronaldo failed to adhere to Italy's strict COVID-19 protocols by travelling to the area from Piedmont to go skiing with his girlfriend Georgina Rodriguez, as part of her birthday celebrations this week.

Both Valle d'Aosta and Piedmont are listed as "orange zone" regions, with travel between such locations prohibited.

Ronaldo, who tested positive for coronavirus last October, may face a fine if found guilty.

"Cristiano Ronaldo had a day off and on your days off you are free to do what you want," head coach Pirlo told a news conference ahead of Saturday's trip to Sampdoria.

"When they are here they are under my control, but outside of here they are free citizens and can take their own actions."

Weston McKennie has become one of Juve's key performers this season since joining from Schalke, scoring four times across all competitions from midfield since the start of December.

Pirlo believes the 22-year-old United States international has plenty of room for further improvement.

"He is so young he can improve everywhere," he said.

"We were the fastest to sign him in Germany and we are so happy to have him with us.

"He is humble and very keen to improve, especially from a technical point of view. I mean, he is a bit rough in ball control, in his body movements, but he can improve quickly.

"He is a healthy kid, he knows he is not done, he is just at the beginning and being aware of this is already a good starting point."

Pirlo has a clean bill of health, with the exception of forward Paulo Dybala, who is still nursing a knee injury.

Federico Chiesa completed the scoring in the 4-0 Coppa Italia win over SPAL and will start after shaking off an ankle problem.

Alvaro Morata put Juve in front from the penalty spot in midweek - his 13th goal of the campaign - and is ready to go again having been compromised by groin pain of late.

"He played last time and we managed to save him some minutes, so tomorrow he will be at the top of his game," Pirlo added.

"We know him well, he dwells so much on enthusiasm and that is what we need to give him back.

"But he has done well, he knows he is very important for Juventus, so I am more than convinced he will go on at his best."

Concussion substitutes will be trialled in the Premier League from February 6, English football's top division has confirmed.

A maximum of two substitutes will be allowed in addition to the stipulated allocation of three substitutions in the event of a player suffering a head injury and showing symptoms of concussion.

The Football Association (FA) and the Premier League applied to the International Football Association Board (IFAB) to introduce the trials .

The 12:30 GMT kick-off between Aston Villa and Arsenal on February 6 will be the first game of the trial, which runs until the end of 2020-21, with an option to extend into next season.

The Women's Super League and Women's Championship will also take on concussion subs from the same date, with the men's FA Cup introducing them from the fifth round on February 9-11.

Concussion substitutes in the FA Cup would be in addition to the five clubs are permitted to make in this season's competition.

A Premier League statement read: "The trial is a result of the IFAB's consultation with stakeholders and recommendations from their concussion expert group to allow additional substitutions for players with actual or suspected concussion."

FIFA has also moved to use concussion substitutes at the forthcoming Club World Cup, although teams at next month's tournament will only be able to make one such replacement per match.

Sergio Ramos' future is not a cause for concern for Real Madrid assistant David Bettoni despite rumours the defender has decided to leave.

Media reports in Spain have claimed Ramos will exit Madrid at the end of the season when his contract expires after failing to respond to the club's latest contract offer, which is said to be worth 10 per cent less than his existing agreement. 

The experienced centre-back has been linked with Paris Saint-Germain, though they are rumoured to have distanced themselves from such stories given it was claimed Ramos was asking for a wage greater than that of Kylian Mbappe. 

Either way, Ramos' future remains uncertain and there appears to be a significant chance of him opting to move elsewhere. 

But Bettoni – still standing in for head coach Zinedine Zidane as he isolates with coronavirus – insists it is not a situation that is worrying right now, as they are focusing on Ramos' recovery from the various ailments that have kept him out of LaLiga action since mid-December. 

"I'm not worried [about the renewal]," Bettoni told reporters. "I see him every day and he's recovering. He is our captain, a great professional. We are not going to risk with him, but I cannot say anything else." 

The 34-year-old is currently out with a knee injury, but he has also recently suffered with a hamstring issue and illness.

Regarding Ramos' fitness, Bettoni added: "Every week he feels better, but we don't want to risk it – luckily now we are only playing once a week. 

"We are evaluating him week by week, we will see how his knee is next week. 

"The Sergio I know has a great heart, he's the captain, he's always there, he's a great professional. He is somewhat annoyed because he cannot play, he always wants to compete. But I don't see him differently, I see him normal." 

Zidane has been away from the Madrid squad for a week following his positive test for coronavirus, though Los Blancos cruised to a 4-1 win in the only match he has been forced to miss. 

He will be absent again on Saturday when Levante visit Estadio Alfredo di Stefano, though Bettoni says Zidane's condition is improving and he has still been able to talk with his staff every day. 

"Zidane is much better," he said. "And every day he gets better. We talk every day, we watch the training sessions, we discuss the contents. 

"He is not physically there, but he is with us. The week was very good. It's true that his presence is missed - it is a pity because of his personality and charisma." 

The pressure is on Madrid in LaLiga – they host Levante on Saturday already trailing leaders Atletico Madrid by seven points, and Diego Simeone's men also have a game in hand.

Bayern Munich have confirmed Leon Goretzka and Javi Martinez have tested positive for coronavirus.

The players are self-isolating at home after returning positive results this week, although the club described both as being in "good health".

They will be unavailable for Saturday's Bundesliga match at home to Hoffenheim.

The European champions then face Hertha Berlin away on February 5 before their Club World Cup campaign starts three days later.

Goretzka has made 20 appearances in all competitions this season, while Martinez, 32, has played 18 times, mostly as a substitute.

Bayern also confirmed goalkeeper Alexander Nubel is likely to be out of action for up to a month.

The former Schalke man, who has only played twice this season, suffered ankle ligament damage on Thursday.

Milan head coach Stefano Pioli insists Zlatan Ibrahimovic is "certainly not a racist" but thinks his clash with Romelu Lukaku could rekindle his best form. 

Ibrahimovic was sent off having scored the opening goal in the Rossoneri's 2-1 Coppa Italia defeat to Inter this week. 

The veteran striker earned his first of two yellow cards after a heated confrontation with former Manchester United team-mate Lukaku, in which he appeared to tell the Belgian forward: "Go do your voodoo s***, you little donkey". 

It was suggested Ibrahimovic was referring to comments made in 2018 by Everton majority shareholder Farhad Moshiri, who said Lukaku had declined a contract extension because a "voodoo message" told him to move to Chelsea - a transfer that never transpired. 

Some accused Ibrahimovic of racially abusing Lukaku, with the Swede responding by stating on Twitter: "In ZLATAN's world there is no place for RACISM." United midfielder Paul Pogba also tweeted to say his old team-mate was "the last person I'd think of as racist". 

Ibrahimovic will serve a one-game ban for his red card but Pioli hopes a line can now be drawn under the incident as Milan focus back on Serie A.

"Ibrahimovic is determined and up for it, as he always is," Pioli said ahead of Saturday's game at Bologna. "Certain things can happen on the pitch; I'm not going to justify that, but you need to draw a line under it and move on. 

"Ibra is certainly not a racist; the club has always been on the front line in the fight against discrimination. Zlatan also needs these situations to get a bit of energy and motivation back." 

Milan's cup exit followed a 3-0 home league defeat to Atalanta that allowed Inter to close the gap on the leaders to two points. 

Pioli says back-to-back losses have not changed his view of his team's potential as he aims to return them to the Champions League. 

"We're not interested in what people are saying outside of the club," he said. "We just need to focus on ourselves, maintain a good balance, continue to work and improve. We know that opinions can change quickly in football. 

"It's useless to look back; we only need to look forwards. I haven't changed my mind on our quality. We have a good team and the ideas are there. We are able to put in consistently good and competitive performances, which we have shown up to now. 

"We're having a great season; we have 18 more points than we did at this stage last season and have closed the gap to our direct rivals.

"The second half of the season will be more complicated and hard-fought. Qualifying for Champions League football won't be easy, but we have the quality to do it."

Mikel Arteta is adamant Martin Odegaard's arrival does not have to negatively impact Emile Smith Rowe's form, with the Arsenal manager convinced they can play together.

Arsenal completed the loan signing of Odegaard from Real Madrid on Wednesday, the Norwegian adding creativity to a squad that had not included Mesut Ozil at all this season prior to his move to Fenerbahce.

The 22-year-old Odegaard had struggled at Real Madrid this term, making just three LaLiga starts for Zinedine Zidane after returning from an impressive temporary spell at Real Sociedad.

But there is great hope that he could make a real impact for the Gunners if he is able to rediscover the form he displayed with La Real, for whom he created a team-high 62 chances and provided six assists in 2019-20.

Despite some expressing doubts over his compatibility with Smith Rowe, Arteta believes the two can play together, while Odegaard's signing will alleviate some of the creative burden.

"Of course, they can play together, and it is not about pushing somebody else [out of the team]," Arteta told reporters ahead of Saturday's clash with Manchester United.

"Emile has earned his right to play the way he is performing - and Martin has to earn that.

"Emile cannot play every single game, as we knew the other day. For example, in the FA Cup he was injured, he could not play.

"The other day [against Southampton on Tuesday], he could only play certain minutes because he was struggling for the last minutes.

"It has been a massive step for him from what he was doing three, four months ago and what he is doing right now. We need options."

DOUBLE THREAT

Smith Rowe has enjoyed a sudden rise to prominence with the Gunners – before Christmas he was exclusively used in cup competitions, but he has started six Premier League matches in a row since.

The first of those was the 3-1 win over Chelsea on Boxing Day, a result that ended a run of seven games without a league victory and began to ease the pressure on Arteta. The Gunners are unbeaten with Smith Rowe in the side in the league this season.

His three assists from open play across the same period is more than anyone else has managed in the Premier League, so concern for Smith Rowe's momentum was an understanding by-product of the initial links to Odegaard.

But, Opta data lends credence to Arteta's assessment they can play together.

None of Smith Rowe's key passes or assists have come from the central third of the attacking half, with all of them coming from wider positions.

While Odegaard operated predominantly from the right at Real Sociedad last term, the highest proportion (31.2 per cent) of his assists and key passes came from the central zone directly outside the penalty area.

Creativity in this zone has been a weak point of Arsenal's this season, with most of their threat coming down the left – Odegaard's arrival might just offer the Gunners a little more balance.

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.

England boss Gareth Southgate is to take part in a study exploring the links between football and dementia and has urged other former professionals to do the same.

The 50-year-old has volunteered to join the HEADING study, led by the London School of Hygiene & Tropical Medicine.

A second independently led study by the University of Nottingham, called FOCUS, is being backed by funding from the Football Association and Professional Footballers' Association.

It is hoped the research can further understanding of possible links between professional footballers and an increased risk of neurodegenerative disorders. Former England international Nobby Stiles had dementia when he died last year, while fellow 1966 World Cup winner Bobby Charlton has the disease.

"This is an incredibly important issue in our game and I'm very happy to play my part in supporting this research," Southgate said via the FA.

"Having turned 50 last year, I am now eligible to take part in the HEADING study, which could provide crucial and valuable insight to help people who play the game now and in the future.

"I would encourage any former professional footballer who is willing and able to take part in the HEADING or the FOCUS study to do so.

"Our involvement is absolutely essential if we are to have a greater understanding of this issue;

Roy O'Donovan scored his first goal as an Australian citizen to earn Newcastle Jets a 1-1 draw against Western Sydney Wanderers.

The former Republic of Ireland B striker fired in an 81st-minute penalty to give the lowly Jets the reward their second-half endeavour deserved.

Former Newcastle frontman Bernie Ibini, who left the Jets in December, had pounced in the 36th minute at Bankwest Stadium to give Wanderers the lead in the A-League clash.

Ibini drove home after Simon Cox went on a weaving run that ended with a 20-yard low shot against the left post, the ball bouncing out kindly for the experienced striker to convert.

Wanderers would have gone top of the table had they held on for three points, but after having much the better of the opening 45 minutes their level dipped in the second half.

Jets substitute Luka Prso was clipped in the penalty area by Patrick Ziegler, who was also freshly off the bench, and O'Donovan snatched the chance to secure a point, firing high into the left corner.

O'Donovan, 35, announced this week that his citizenship had come through, having spent the last five and a half years playing in Australia.

The point nudges Wanderers up to second place after five games, albeit having played one more match than the teams around them.

For the Jets it was a first draw of the campaign after one previous win and four defeats.

Chelsea are reportedly interested in Borussia Dortmund star Erling Haaland and Bayern Munich defender David Alaba. 

Haaland and Alaba have been linked with moves, with the latter almost certain to leave Bayern when his contract expires at the end of the season. 

Chelsea spent big last year – but they are apparently eyeing the pair.

TOP STORY – CHELSEA INTERESTED IN HAALAND AND ALABA

Chelsea are interested in signing Dortmund star Haaland and Bayern defender Alaba ahead of 2021-22, according to Sky Sports.

Real Madrid have been strongly linked with the duo, while Alaba is said to be a target for several other European giants.

Thomas Tuchel has replaced Frank Lampard at the helm for Chelsea, who are eighth in the Premier League.

ROUND-UP

- Jesse Lingard could join West Ham. Sky Sports reports they have offered a £1.5million loan fee and to pay Lingard's wages for the rest of the season to land him on loan from Manchester United.

- Amid reports Lucas Torreira could leave Atletico Madrid, where he is on loan from Arsenal, to join Monaco, it seems that may not be the case. Fabrizio Romano reports Monaco are not negotiating for Torreira.

- Bayer Leverkusen are confident of completing a deal for Leicester City midfielder Demarai Gray, according to Sky Sports.

- Struggling for game time at Arsenal, Ainsley Maitland-Niles could make a move. The Athletic reports West Brom are looking at the 23-year-old for a potential loan deal.

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."
