Ronald Koeman backed Antoine Griezmann but said goals would be the "best medicine" to boost the Barcelona forward's confidence.

Griezmann's last goal came against Ferencvaros in the Champions League on December 2, and he has just three in 16 LaLiga appearances this season.

A trip to Los Carmenes to face Granada on Saturday could help the France international, who has been involved in four goals (three goals and one assist) in his past five visits to the ground in LaLiga.

Barcelona coach Koeman said while Griezmann was working hard, goals would be best for the 29-year-old.

"Any player needs confidence in himself, his team-mates and the place where he plays. This starts with the player," he told a news conference.

"As a coach, I can communicate with [Griezmann], show him things and footage of potential things to improve, but at the end it's the player who has to show his quality and give effectivity to the team.

"It's not the case that Antoine doesn't work, he works a lot in any position. The other day he recovered a lot of balls, he gave an assist to Leo [Messi].

"But it's time that he scores, because scoring goals is the best medicine to have total confidence in yourself."

Griezmann has converted just 22.2 per cent of his big chances in LaLiga this season, his lowest in any campaign since at least 2012-13.

Barcelona are fourth in the table, seven points behind Atletico Madrid but having played two more games.

Manchester City manager Pep Guardiola admitted there was uncertainty about what condition players would be in after contracting coronavirus.

The Premier League giants are set to regain Ederson, Ferran Torres and Tommy Doyle ahead of their FA Cup clash against Birmingham City on Sunday.

But Guardiola said it still remained unclear just how players would return after testing positive for COVID-19.

"The doctors don't know how the body will react, maybe one month or one and a half years, no-one knows what is going to happen," he told reporters.

"Imagine after being found positive, whether you know if you are going to play at a high level. That is why the boys are a little but concerned about this and are careful.

"Because some players react well, but Ilkay Gundogan took some time to recover after the summer and struggled a little bit. So that is why it's good news they are back in the training sessions and locker room.

"But when they will be able to play minutes, we have to talk with them and the doctors and the physios and how they react to the training session and the day after. Every player and case is different and you have to be alert."

City are unbeaten in 12 games in all competitions and sit fifth in the Premier League table.

They have played two fewer games than Liverpool and one less than Manchester United, who are four points clear of them.

Bayern Munich fell victim to a "brutally effective" Borussia Monchengladbach in their humbling 3-2 defeat on Friday, according to Hansi Flick.

Robert Lewandowski's penalty – his 20th Bundesliga goal of the season – and a fine strike from Leon Goretzka put Bayern in control of the Bundesliga clash at Borussia-Park inside 26 minutes.

However, a wayward pass from Benjamin Pavard led to a quick break that finished with Jonas Hofmann scoring, and the Gladbach midfielder was played onside by Niklas Sule as he doubled his tally before half-time after Joshua Kimmich was caught in possession by Lars Stindl.

Sule then gave the ball to Hofmann inside his own half four minutes after the restart and Florian Neuhaus subsequently atoned for conceding the first-half spot-kick with a bizarre handball by netting the winner.

Gladbach consequently became the first team since Cologne in February 2011 to beat Bayern in a Bundesliga game after falling 2-0 down.

"We had hoped for a different ending to this game and expected it, but in the end we were punished. We lost the ball unnecessarily three times and the opposition was brutally effective in finishing those chances," Flick told a post-match news conference.

"When you ask me how to prevent that, on the one hand you have to keep the mistakes to a minimum, or avoid them, and on the other hand you have to cover your deep positions twice.

"We suffered similar situations on their first two goals. Hofmann went deep from midfield and we moved forward too quickly and opened the centre without covering the deep position, and with the second we should have kept going and covering the positions.

"That shouldn't happen and it's not a nice situation to be in, but a defeat, even if it's Bayern Munich, is part of the game. In the second half the team tried everything to achieve a positive result but unfortunately it didn't work."

Manuel Neuer has now conceded in 10 straight Bundesliga games for the first time in his career, with Bayern letting in 16 goals since their last clean sheet against Eintracht Frankfurt on October 24.

Bayern have conceded 24 goals through 15 matches in the top flight this season, the most they have shipped at this point of a Bundesliga campaign since 1981-82.

Flick added: "I've said it a few times, we are making too many mistakes. You can't deny that the team tried to win.

"We had to fight today, we knew it would be a difficult game. Don't forget [Gladbach] is a team that played in the Champions League against top opposition and prevailed, so we needed this compact team performance and we showed – with the exception of these three situations.

"But of course, we're not satisfied with the result. We all know we need to show even more concentration in our defensive work in the crucial moments. We have to cover the deep positions and that's the challenge we have, and we have to improve in the coming weeks."

Bayern are back in action against 2. Bundesliga side Holstein Kiel in the DFB-Pokal on Wednesday.

Jurgen Klopp lavished praise on Aston Villa's young players after they made Liverpool battle for their place in the FA Cup fourth round on Friday.

As a result of a training ground Covid-19 outbreak on Thursday, the hosts were forced to send Under-23s boss Mark Delaney and a team comprised of youngsters to face the Premier League champions at Villa Park.

They more than held their own for large parts, and even got to the half-time break level thanks to a well-taken Louie Barry goal.

Liverpool took the game away from Villa in the second period, ultimately running out comfortable 4-1 winners, but Klopp was impressed with what he saw from the opposition.

The German also took pleasure in the fact his far more experienced side eventually solved the 'football problems' in front of them.

He said: "The boys did really well, the kids of Aston Villa did really well, were organised and all that stuff. 

"It was clear. We scored an early goal, a nice one, and then we didn't play quick enough anymore, didn't move fast enough, didn't play the right spaces.

"These are football problems and we solved the football problems with football in the second half. So, I'm really fine with it. 

"It was a tricky one. I've never before had this kind of challenge in my life, that you have no idea who you're playing against – absolutely no idea; that you prepare a meeting and then you can throw all the preparation, all the videos in the bin and then you have to start new. 

"That's football and academy players are good players. Last year we played here with our kids and they gave Aston Villa a proper game as well. That's just how it is. 

"These young kids can all play football and if you don't play well against them you have problems. Second half, we played exactly like we should have played from the beginning and that's why we won really, the right way."

Klopp withdrew captain Jordan Henderson at half-time in Birmingham but went on to reveal that the change was not down to a new fitness issue.

Asked about a possible injury blow, he replied: "No, no, Hendo and Thiago was clear before the game that we do it like this: 45, 45. Absolutely no problem."

The German also explained that he had no concerns about his squad being exposed to coronavirus despite the late change to Villa's proposed line-up.

He continued: "No, no reservations. We trust the authorities, we had our test results come back yesterday as well, everybody was negative. Then the FA did what they thought is right with the U23s, they got tested, we got their results this morning I think at 10 o'clock.

"We were on the car park at the airport. So, then everything is fine."

Frank Lampard vowed he will fight to make Chelsea successful and declared he would have become a pundit if he had wanted an "easier" life.

The head coach, who in his playing days became Chelsea's record goalscorer, has been unable to prevent a mid-season slump that has seen the Blues slide down the Premier League table.

Four defeats in the last six games has been the sting in the tail after a long unbeaten run, yet Lampard is confident there is enough quality in his squad to turn around their season.

"I've been playing football since I could walk, and playing professionally for 20-odd years," Lampard said.

"If I didn't want that challenge, I could have sat on the telly and done an easier job. I could have been a pundit and commented on what everyone does with hindsight whenever I want, but I don't want to do that."

Instead, he is determined to prove he is the right man for the Stamford Bridge top job, and should he sense any player does not match his ambition, Lampard will consider if they belong at the club.

"The players here I feel have a real desire to get out of this mini run of bad results. I can see that in them," said Lampard. "And if there are players who don't have those concerns to get out, I think they have decisions to make.

"If there are opportunities for players to leave, it would have to be right for them, right for the club and right for myself, then that could happen. But if not, we keep fighting and moving on."

Chelsea have a break from Premier League duties when they face Morecambe in the FA Cup third round on Sunday. They lost to Arsenal in the final of last season's competition.

Lampard is set to shuffle his squad for the game with fourth-tier Morecambe, giving fringe players and possibly some academy prospects the chance to impress.

After that it will be back to the Premier League, when he expects senior players to be straining every sinew in training to earn selection.

The likes of summer signings Kai Havertz and Timo Werner have struggled this season, but Lampard says every player should be desperate to make an impact.

Havertz has found it difficult to make the transition from the Bundesliga to the Premier League, with just one goal, two assists and a mere 23 touches in the opposition penalty area for Chelsea after 15 games in the competition, 10 of which he started.

Last season, at Bayer Leverkusen, Havertz totted up 12 goals, six assists and had 140 touches in the opposition box across 29 league starts and one substitute appearance.

Lampard was determined not to focus on individuals and appears keen to give his recent recruits time to bed in at Chelsea. His concern is a wider one and addresses every player at the club.

He said: "I don't ask for them to be jumping up and down when they go home about how great I am. What I'm asking for when you're here is, to train well, back your team-mates, have a determined attitude every day, and that's it.

"I don't expect it to be a popularity contest with myself - I don't think I ever felt that in a dressing room with any manager in the best of times or in tough times.

"The players have to keep fighting in tough times. The quality is in the group, without a doubt. There will be bumpy moments and we have to stick together."

Emile Smith Rowe has the "huge potential" to match the exploits of young England stars Phil Foden and Jadon Sancho, according to Arsenal boss Mikel Arteta.

The Gunners begin their FA Cup defence at home to Newcastle United on Saturday, buoyed by a sharp upturn in their Premier League form.

A dominant 3-1 London derby win over Chelsea on Boxing Day sparked an ongoing three-match winning run.

Smith Rowe was handed a starting berth in that game and has kept his place after impressing in the number 10 role, with the 20-year-old giving Arteta's team an overdue shot of creative intent.

In 2017, Smith Rowe was part of the England squad that won the U17 World Cup, with Foden named player of the tournament.

Sancho featured during the group stages before being called back to club action by Borussia Dortmund, and Arteta acknowledged the duo are ahead of Smith Rowe in their development.

"He has huge potential. He really wants it and he has the personality when he goes on the field to express and play the way he can play," said Arteta, who coached Foden and - more briefly - Sancho at Manchester City as part of Pep Guardiola's backroom staff.

"To do it in a consistent way is a different thing. The boys that you mentioned, they've done it. It's true that they're ahead in their development phase because they've played many more minutes and games in the last two seasons.

"But he is capable of doing that. Whether he's going to do it will depend on how he continues to develop, how he takes the chance that he has in front of him and how much we can help him to achieve that."

Underwhelming loan stints at RB Leipzig and Huddersfield Town in the past two years preceded a pre-season shoulder injury, but a player dubbed "The Croydon De Bruyne" by some Arsenal fans has shown he is ready to make up for lost time.

"A lot of things have happened to him in the past year," Arteta acknowledged. "He needs to establish himself here, he needs to be successful here, he needs to really find his role and his position in the team and in the club.

"That will help him to have clear path. We really believe in him. He needs to have no fear and go for it, because he has the quality."

That quality has certainly been to the fore this season, with Smith Rowe's four assists coming at a rate of one every 93.5 minutes across seven appearances in all competitions.

With the youngster in the side, Arsenal average 2.9 goals per game. The 4-1 Europa League triumph over Rapid Vienna – in which he scored – was one of six victories Smith Rowe has been involved in this term, amounting to a win percentage of 85.7 per cent that plummets to 40 in the 20 games he spent as a spectator.

It feels infeasible that Arteta will leave him out of such a large proportion of games again but the former Emirates Stadium skipper pointed towards the examples of Bukayo Saka and Gabriel Martinelli, who completed an exciting attacking midfield trident alongside Smith Rowe against Chelsea and Brighton and Hove Albion, when discussing how younger players must have their workloads managed.

That could mean some stints playing in different positions, as Saka has during his fledgling Arsenal career, although Arteta cannot deny the much-needed lift his breakthrough stars have given Arsenal, even as he tries to manage expectations.

"Sometimes a team is a little bit concerned and has some fear because of the results, because of the pressure," he added, before noting the impact through "enthusiasm" the younger members of his squad have had.

"I think they were really helpful because they were re-energising to the team. They pushed the team into a different direction and a different rhythm as well.

"But, of course, the young players need that solidity, experience and maturity that the older players bring. It's a good combination."

Jose Mourinho revealed Tottenham have managed to carefully "hide" their COVID-19 problems as he insisted Premier League chiefs must not let the season descend into chaos.

The Spurs manager is relishing the distraction of an FA Cup tie at Marine on Sunday, describing the competition as "absolutely beautiful" and promising to take a star-studded squad to face the minnows.

But Tottenham would be left in an "impossible situation", according to Mourinho, if next Wednesday's Premier League clash with Aston Villa is called off.

Villa have experienced a major outbreak of coronavirus cases and their first-team training facilities were closed ahead of Friday's cup clash with Liverpool.

Tottenham have already had a London derby with Fulham called off under similar circumstances, and fixtures are piling up.

Mourinho wants a solution to be found and appealed for "leadership" from league top brass, suggesting there should be ways found to allow games to go ahead.

"The only thing I can say is that since pre-season, we knew that eventually it would happen to us, to have difficult situations to manage and to play again with 14 players," Mourinho said.

"I think every club was mentally ready for it."

Mourinho pointed to his former club Chelsea fielding Petr Cech at under-23 level recently, with the veteran goalkeeper coming out of retirement in case he is needed in a crisis.

"Every club was mentally ready for an extreme situation of having a lot of players not available to play," said Mourinho.

"In our case, we didn't have that extreme situation yet but we had problems. We had problems that of course with the legal right that we had, we managed to hide it, to hide it in a way by not telling who was positive and who was not able to play.

"But we are also having our problems. But we always thought we would always play. I cannot say much more than that."

Tottenham, like all clubs, have not been obliged to identify players who have tested positive for COVID-19, which has allowed Mourinho to avoid cases being publicised.

Those affected must go into self-isolation, but it appears Tottenham are in a good way ahead of their trip to Marine.

Mourinho remembered facing lower-league sides during his coaching career, pointing out the day his Chelsea side lost 4-2 to Bradford City in the FA Cup fourth round, back in the 2014-15 season.

"The FA Cup is absolutely beautiful," he said. "That's why, even knowing that I would love to rest all my guys. I cannot do it. It's not about being afraid, it's about giving the guys what they deserve.

"I'm not taking everybody. But out of 20, I take 19 first-team players. so you can imagine how strong we go."

Mourinho promised he would even enter the Marine club raffle, which offers a top prize of managing the eighth-tier team in a pre-season friendly. With no gate receipts, Marine are understandably looking for other ways of monetising the glamour tie.

"I will buy a ticket. Even if I win, I cannot do it," Mourinho said. "I don’t think I will have conditions to do that, but the meaning of it yes, I will be buying it."

The Northern Premier League North West part-timers and Spurs will go down in the record books as having the biggest gap between each other in the pyramid in the history of the FA Cup when they meet at Marine Travel Arena.

Marine sit sixth in their section of the eighth tier of English football, while Tottenham are fourth in the Premier League, reached the final of the EFL Cup this week and remain in the hunt for Europa League glory.

Mourinho will demand victory, of course, and will be quietly testing his players' appetite for the romance of the game.

"This is just a match that can show me how much they love football," he added. "Nothing else."

Matthijs de Ligt has tested positive for coronavirus, Juventus have confirmed.

Juve were without Juan Cuadrado and Alex Sandro against Milan on Wednesday due to positive COVID-19 tests and the Netherlands international has also entered self-isolation.

The Bianconeri face Sassuolo on Sunday before taking on Genoa and Inter in the following week.

A club statement read: "Juventus Football Club announces that, during the checks provided for by the protocol in force, Matthijs de Ligt has emerged positive with COVID-19.

"The player has already been placed in self-isolation."

De Ligt missed the start of the 2020-21 season after undergoing shoulder surgery in August but has started 12 straight games in all competitions since returning to action on November 21.

Jonas Hofmann played a pivotal role as Borussia Monchengladbach incredibly came from two goals down to defeat Bundesliga champions Bayern Munich 3-2 on Friday.

Robert Lewandowski scored his 20th top-flight goal of the season from the penalty spot after an inexplicable handball from Florian Neuhaus, and Leon Goretzka had Bayern cruising at Borussia-Park in the 26th minute.

However, Hofmann struck twice in the space of 10 minutes to send the teams into half-time level and Neuhaus atoned for his earlier error with what proved to be the winner in the 49th minute.

Gladbach consequently became the first team since Cologne in February 2011 to defeat Bayern in the Bundesliga after falling 2-0 down.

Lewandowski put Bayern in front from the penalty spot following a bizarre handball by Neuhaus, though referee Harm Osmers only pointed to the spot after a VAR check.

Bayern doubled their advantage six minutes later, Goretzka intercepting Matthias Ginter's pass and drilling a venomous effort past Yann Sommer after a one-two with Leroy Sane.

Gladbach reduced the deficit when Rami Bensebaini regained the ball high up the pitch and a quick passing move ended with Hofmann sliding Lars Stindl's throughball past Manuel Neuer.

The hosts drew level in first-half stoppage time when Stindl dispossessed Joshua Kimmich and fed Hofmann for another cool finish - the VAR confirming he was onside when the pass was played.

Gladbach completed the turnaround four minutes after the restart, Hofmann intercepting Niklas Sule's pass and teeing up Neuhaus to curl a wonderful effort into the top-right corner.

Marco Rose's men sat deep and Ginter cleared a header from Sule off the line in the 91st minute, opening the door for RB Leipzig to replace Bayern at the Bundesliga summit if they can beat Borussia Dortmund in a mouthwatering clash on Saturday.

What does it mean? Worries at the back for Flick

Bayern's defensive struggles continued against Gladbach, with Neuer now on a 10-game run without a clean sheet in the Bundesliga for the first time in his career.

He was not helped by Benjamin Pavard giving away possession prior to Hofmann's first, while Sule played a role in allowing the other two Gladbach goals.

Securing the future of David Alaba, who will be out of contract at the end of the season, never seemed quite so important.

Having it Lars

Most teams would think the game is beyond them when falling 2-0 down to Bayern, but Gladbach captain Stindl led by example to turn the game around. He set up both of Hofmann's goals with a pair of quality passes and contested 11 duels before being substituted in the 82nd minute.

Sluggish Sule

Sule replaced Jerome Boateng in the centre of defence but endured a disappointing outing. He played Hofmann onside for the equaliser just before half-time and within minutes of the restart his stray pass resulted in Neuhaus putting Gladbach in front.

What's next?

Bayern are in DFB-Pokal action against 2. Bundesliga side Holstein Kiel on Wednesday, while Gladbach have a week to prepare for a Bundesliga clash with Stuttgart.

Bayern Munich goalkeeper Manuel Neuer is enduring the worst run of his Bundesliga career.

With Jonas Hofmann's goal in the 35th minute of Bayern's meeting with Borussia Monchengladbach on Friday, Neuer failed to keep a clean sheet for the 10th straight top-flight game.

It is the first time the 34-year-old keeper has conceded in 10 successive Bundesliga matches during his 15 seasons in the competition.

Neuer's previous worst streak was a run of nine games between September and December in 2018.

The last time Bayern kept a clean sheet in the Bundesliga was in their 5-0 triumph over Eintracht Frankfurt on October 24.

Tommy Lasorda, who led the Los Angeles Dodgers to two World Series titles and became one of the franchise's most beloved and iconic figures, died on Thursday at the age of 93. 

The Dodgers announced Lasorda's death on Friday in a statement. According to the team, he suffered a sudden heart attack on Thursday, just two days after being released from a long hospital stay. 

Lasorda spent 71 years with the Dodgers organisation as a player, scout, coach, manager and front office executive. He retired from managing in 1996 after a 21-year run highlighted by World Series championships in 1981 and 1988. 

"In a franchise that celebrated such great legends of the game, no one who wore the uniform embodied the Dodger spirit as much as Tommy Lasorda," team president and CEO Stan Kasten said in a statement. "A tireless spokesman for baseball, his dedication to the sport and the team he loved was unmatched. He was a champion who at critical moments seemingly willed his team to victory. The Dodgers and their fans will miss him terribly. 

"Tommy is quite simply irreplaceable and unforgettable."

Lasorda had a short major-league career as a left-handed pitcher with the Dodgers and Kansas City Athletics from 1954-56 before retiring as a player in 1960 and joining the Dodgers as a scout the following year. He later managed several of the organisation’s minor league teams before being promoted to serve as the major league club's bench coach under Hall of Famer Walter Alston in 1973. 

He took over managerial duties following Alston's retirement near the end of the 1976 season and began one of the longest tenures with one team in major league history. He is one of only four skippers, along with Alston and Hall of Famers Connie Mack and John McGraw, to manage the same team for 20 consecutive seasons or more. 

A two-time National League Manager of the Year, Lasorda compiled a 1,599-1,439 overall record and led the Dodgers to seven National League West titles and eight playoff appearances while reaching the World Series four times. He later guided the United States to a gold medal at the 2000 Sydney Olympics. 

Lasorda moved into a role as the Dodgers' vice president following his retirement in 1996 and was elected into the Baseball Hall of Fame in 1997. He had served as a special advisor to the team since 2004 and was present at Texas' Globe Life Field for the Dodgers' Game 6 victory over the Tampa Bay Rays in October that clinched the franchise's first World Series title since his 1988 squad. 

"It feels appropriate that in his final months, he saw his beloved Dodgers win the World Series for the first time since his 1998 team," MLB Commissioner Rob Manfred said in a statement. "On behalf of Major League Baseball, I send my deepest sympathy to his wife of 70 years, Jo, and their entire family, the Dodger organisation and their generations of loyal fans."

Lasorda had been plagued by health issues in recent years. A heart attack led to his retirement from managing in 1996 and he suffered another in 2012. He was admitted to a California hospital with heart-related problems in November and spent several weeks in intensive care before being released earlier this week.  

A native of Norristown, Pennsylvania, Lasorda is survived by his wife, Jo; his daughter, Laura and one granddaughter.
