Joshua Kimmich's stunning 90th-minute equaliser spared Bayern Munich's blushes as the Bundesliga champions rescued a 1-1 draw at home to Koln on Tuesday.

Bayern had been on the verge of their first home league loss since last January before their captain took centre stage, though it was not enough to restore their six-point lead at the summit following RB Leipzig's 6-1 demolition of Schalke.

Ellyes Skhiri, who scored twice in Koln's remarkable 7-1 win over Werder Bremen on Saturday, put the Billy Goats ahead amid a purposeful opening.

Koln were under pressure for long periods thereafter, however, and they could not see the win out as Kimmich struck from distance at the end.

Julian Nagelsmann dismissed any suggestion that Thomas Muller's omission against RB Leipzig hints that the forward's Bayern Munich future is uncertain.

Muller came on in the 83rd minute as Bayern drew 1-1 with Leipzig on Friday.

The 33-year-old has struggled with injuries this season and has played only nine Bundesliga games.

Muller also failed to spark at the World Cup, as Germany crashed out in the group stage.

Nagelsmann, though, says the media has made too much of Muller being a substitute.

"With Thomas, this is a bigger topic in public than it is for us," he told reporters ahead of Tuesday's clash with Koln.

"When you've been injured for so long, you're always challenging [for your place].

"Thomas also wants the competition. He has an outstanding character, but I haven't made up my mind about if he plays."

Muller could not get Bayern over the line against Leipzig, with the champions having struggled to create much in the way of opportunities in the second half at Red Bull Arena.

Eric Maxim Choupo-Moting put them ahead late in the first half, netting Bayern's 50th Bundesliga goal of the campaign, before Marcel Halstenberg equalised, but Nagelsmann wants more intensity in attack.

He said: "We didn't build up optimally, it was too slow. We sometimes had good actions after winning the ball, but we made wrong decisions.

"I also warned the team beforehand about Leipzig's strength in transition... There were one or two less-than-perfect situations on both sides."

Koln, on the other hand, go into Tuesday's game having thrashed Werder Bremen 7-1.

"I think the seven goals mean something more to Koln than to us," Nagelsmann said. "They do that very well, they're active and good at counter-pressing.

"[Coach] Steffen Baumgart does that very well. They always play with an open mind, very offensive. We have to be aggressive."

Bayern Munich's honorary president Uli Hoeness has urged patience with the club's long-term goalkeeping situation.

Manuel Neuer's leg break forced the Bundesliga leaders to be active in the January market, signing Yann Sommer from Borussia Monchengladbach on a two-and-a-half-year deal for a reported €8million.

While that deal solves the goalkeeping conundrum for the remainder of the campaign, it leaves questions for next season and beyond given the ages of both goalkeepers.

Neuer, 36, and Sommer, 34, are both experienced enough to want regular first-team action and the situation is complicated further by Alexander Nubel, who will return from a loan spell with Monaco, while Sven Ulreich is also on the books.

The quartet will give Julian Nagelsmann a selection headache next term but Hoeness believes it is a problem that can be solved further down the line.

"I think it's strange that the problems of June are discussed in January," he told Sport1.

"It was necessary to find the best solution for the next six months. Yann Sommer is the optimal solution at the moment.

"Everything else with Nubel and Ulreich will be seen in June when we know more about Manuel's condition.

"Bayern are happy to have a goalkeeper in Yann Sommer who is now solving our problems. I would urge patience."

While there have been questions on whether Neuer could have to pay a penalty due to his injury, which was caused by a skiing accident, Hoeness rebuffed those suggestions with a blunt response.

"Manuel knows he made a mistake. Anything can happen in life. It's an accident. We shouldn't forget what he did for Bayern," he added.

"Bayern's success is also due to the fact that such issues are solved very humanely and socially. A million or two doesn't matter. People come before money."

Koln boss Steffen Baumgart quickly turned his attentions towards containing Bayern Munich after watching his rampant side hit Werder Bremen for seven on their return to Bundesliga action on Saturday.

Baumgart's men, who began the day four points behind their visitors in the table, ended an incredible opening period 5-1 up after Linton Maina, Ellyes Skhiri and Denis Huseinbasic added to Steffen Tigges' double.

Huseinbasic's 36th-minute strike gave Koln the earliest five-goal lead in their Bundesliga history, before Skhiri's second, coupled with a Marco Friedl own goal, rounded off the scoring after the break.

While Baumgart was pleased to see Koln halt a five-game winless run in their first outing since the World Cup, he refused to get carried away ahead of Tuesday's daunting clash with the champions.

"It's a game that you won't always have, of course," he said at his post-match press conference.

"We scored five goals from the first five shots on goal. We are happy about the result. We went forward with a lot of speed and earned the goals.

"On Tuesday, however, we have a team in front of us that shot down other teams with a similar result. We know what to expect."

Saturday's win represents the first time Koln have hit seven goals in a game since a 7-0 thrashing of Eintracht Frankfurt in October 1983.

The visitors, meanwhile, are now winless in their last 11 Bundesliga trips to Koln (D6 L5).

Bayern Munich were pegged back by RB Leipzig as the Bundesliga returned with an entertaining 1-1 draw on Friday.

Marcel Halstenberg struck in the 52nd minute at Red Bull Arena to draw third-placed Leipzig level against the league leaders.

Julian Nagelsmann had seen his team take the lead against his former club eight minutes before half-time, with Eric Maxim Choupo-Moting picking up where he left off before the World Cup break.

Bayern were lucky ex-Leipzig defender Dayot Upamecano stayed on the pitch after a rash challenge on Dominik Szoboszlai, but the visitors' run of 10 successive wins in all competitions came to a halt regardless.

Jamal Musiala was a rare bright spot for Germany in Qatar, and the teenager teed up the first chance when he played in Serge Gnabry, whose shot was deflected against the post by another World Cup star Josko Gvardiol.

Leon Goretzka thought he had nosed Bayern ahead when he nodded in from Choupo-Moting's flick-on, but the goal was disallowed for Matthijs de Ligt straying offside in the build-up, with the VAR upholding the linesman's decision.

Bayern were not to be denied the lead, though, with Choupo-Moting turning in his seventh Bundesliga goal of the season after meeting Gnabry's pinpoint left-wing cross.

Yann Sommer had little to do in the first half, but the Bayern debutant was picking the ball out of his net seven minutes after the restart.

Joshua Kimmich's slack pass put Bayern in trouble, with the champions failing to clear their lines and eventually allowing Halstenberg to prod home from close range despite appeals for a foul in the build-up.

Upamecano was fortunate to escape a red card when he scythed down Szoboszlai and appeared to be the last defender, yet Bayern made their luck count to come away with a point.

Yann Sommer has joined Bayern Munich from fellow Bundesliga side Borussia Monchengladbach.

Sommer, a Switzerland international, has regularly been one of the best-performing goalkeepers in Germany during his time at Gladbach.

The 34-year-old, whose contract was due to expire at the end of the season, has joined Bayern on a two-and-a-half-year deal for a fee reported to be in the region of €8million.

Bayern wanted to add to their goalkeeper options after Manuel Neuer was ruled out for the rest of the season having broken his leg while skiing in December.

The possibility of recalling Alexander Nubel from his loan at Monaco had been explored, though Sommer always seemed to be the priority target.

Despite Gladbach's insistence they did not wish to sell him, Sommer reportedly asked to leave, and a deal was struck between the clubs on Wednesday.

"I'm really looking forward to my new role at Bayern. It's a big club with power, we've often played against each other - I know about the enormous quality and charisma of this club," Sommer said on his transfer.

"I'm proud to be part of Bayern now. We have big tasks ahead of us. I'm really looking forward to the start with my new colleagues and to everything that's coming.

"I would like to thank Borussia Monchengladbach for eight and a half great years and for making this transfer possible."

Sommer joined Gladbach in 2014 and made 272 Bundesliga appearances. Hoffenheim's Oliver Baumann is the only goalkeeper to have played more times in the competition in the same period.

Of goalkeepers to make 10 or more Bundesliga appearances in that time, Sommer's save percentage of 71.1 is the seventh best and ranks similarly to Neuer's (72.5). He has kept 70 clean sheets.

Sommer has only made 10 appearances in the competition this season but boasts the second-best save percentage (77.1) behind Union Berlin's Frederik Ronnow (79.1).

Based on Opta's expected goals on target conceded (xGOT) data, Sommer's saves have prevented 4.1 goals in the Bundesliga this season, the highest figure in the division, with Neuer ranked second (3.8).

Bayern restart their campaign against Julian Nagelsmann's former team RB Leipzig on Friday.

Julian Nagelsmann is anxious to see Bayern Munich's pursuit of Yann Sommer reach a conclusion as the Bundesliga champions prepare to return to action at RB Leipzig on Friday.

Bayern have been strongly linked with Borussia Monchengladbach goalkeeper Sommer since Manuel Neuer broke his leg during a skiing trip last month.

With Sven Ulreich the only other senior goalkeeper in Bayern's squad and Alexander Nubel reportedly reluctant to return from a loan spell at Monaco, Nagelsmann said the club has "a duty" to sign another shot-stopper last week.

Bayern chief executive Oliver Kahn has revealed discussions are ongoing regarding a move for Sommer, and Nagelsmann is eager for the transfer saga to reach a resolution. 

"I've been a coach long enough to know it's never easy. There are always more than two parties that need to be satisfied," Nagelsmann said at Wednesday's pre-match press conference.

"We need a decision to happen. I'd like to change the transfer window so it doesn't affect the ongoing matches as much.

"It's normal that at some point you want to have a certain amount of peace and quiet in this position.

"Integrating a new goalkeeper is not rocket science. This usually takes about 15 minutes, it works quickly. It depends on the goalkeeper, generally the behaviour is very similar."

With Sommer having 272 Bundesliga appearances to his name, some have suggested his arrival could mark the end of Neuer's time as Bayern's number one, but Nagelsmann remains focused on the immediate need for reinforcements.

"It's more a matter for the people further up," Nagelsmann said. "I might have some things to say on that, but my business is day-to-day business, winning games.

"I assume that Manuel Neuer, a great goalkeeper, will come back in the summer. We're looking forward to a player of his quality returning."

Meanwhile, Nagelsmann is yet to decide whether Thomas Muller will see off competition from Eric Maxim Choupo-Moting to start as Bayern's striker against Leipzig, saying he is comfortable using the 33-year-old in a variety of positions.

"Thomas had an injury where he couldn't play as much in the first part of the season. Thomas is an extremely important player for me, I'm always exchanging with him," Nagelsmann said.

"He's aware that Choupo-Moting is doing very well, but he's also intelligent enough to know that he is world-class in several positions.

"It's important that all the players are in top condition and that we see that on Friday. The same goes for Thomas, he's very flexible. He likes to play in attacking midfield but can play in different areas, so he's going to be important for Bayern going forward. 

"I've already decided on six positions out of 11. I won't reveal whether Choupo-Moting is among the six. I'll sleep on it for two more nights."

Lothar Matthaus has urged Julian Nagelsmann to think again and ditch the idea of veteran Thomas Muller playing as a striker for Bayern Munich.

Muller featured as Bayern's furthest man forward in a 4-4 friendly draw against Salzburg on Friday, as the German champions prepare for the resumption of the Bundesliga season.

It remains to be seen who leads the line when Bayern return to competitive action against RB Leipzig on Friday, but Muller is an option for that role.

According to Matthaus, Germany's most-capped player and a long-standing former Bayern player, Muller simply is not suited to the role.

He has mostly operated in midfield, on the flanks, or behind a striker, proving to be an accomplished support act to the Robert Lewandowski goals show in recent seasons.

Now that Lewandowski has departed for Barcelona, and with injuries affecting Nagelsmann's options, Muller might have to fill the stop-gap role.

Yet Matthaus told German magazine Kicker: "You're not doing Thomas any favours, he's in the wrong place up front.

"Let him play where he has his strengths. Thomas belongs behind the striker, like in the past with Robert Lewandowski."

Former Liverpool forward Sadio Mane is among the Bayern forwards sidelined by injury at present, with Eric Maxim Choupo-Moting another option as a starting striker for Bayern in the second half of the season.

Muller has just three goals in 15 games for Bayern this term, having hit 14, 15 and most recently 13 in the past three seasons. His shot conversion rate is also down, compared to those seasons, at a disappointing 12 per cent.

Muller, who has 121 caps for Germany, has elected to remain available to his country in the wake of their miserable World Cup group-stage exit.

He is 29 caps behind Matthaus' caps record, and the man in possession of that mark thinks 33-year-old Muller should only stay involved if he is going to play a significant role for national coach Hansi Flick.

Pointing to a case from recent history, Matthaus said: "I don't want to see him in the role of Lukas Podolski: to be there and play as a joker for the statistics in the 90th minute."

Joshua Kimmich joked he may have to play until the age of 45 to lift an international trophy as he rued Germany's dire showing at the 2022 World Cup.  

Having been eliminated in the group stage at Russia 2018 and fallen to England in the last 16 at Euro 2020, Germany arrived in Qatar in the midst of a dismal run of tournament showings.

Hansi Flick's side were left with a familiar sinking feeling as they failed to recover from a shock defeat to Japan in their Group E opener, missing out on a place in the round of 16 despite taking four points from games against Spain and Costa Rica.

Bayern Munich midfielder Kimmich has now been a Germany regular at four major tournaments, and their shortcomings have left him with a "bitter" taste.

Kimmich is back in Doha for a mid-season training camp with Bayern, and asked in a press conference about Germany's chances of winning a major trophy as they look ahead to hosting Euro 2024, he said: "I just have to keep playing until I'm 45, then we will, hopefully."

Reflecting on Germany's World Cup exit, the 27-year-old added: "We had big objectives and wanted to reach something. 

"Eventually, we got knocked out early again. After 2018, the Euros and now another tournament like this, it is very bitter.

"You don't get that many chances with the national team, so this is not something you can just easily forget and move on from because it is what it is."

Kimmich believes Germany could have grown into the tournament had they qualified from their group, but he acknowledges other sides – including eventual champions Argentina – arrived in Qatar in better form.

"I thought that in 2018, many things weren't working, also internally on our team. Against England [at Euro 2020], it felt like a 50-50 game," Kimmich said.

"Last year, I don't want to say everything was great but in the end, those 30 minutes against Japan cost us the tournament. If we had drawn there, we would definitely have progressed.

"We were also missing self-confidence, especially when I look at other teams. Italy before the Euros had a long streak of unbeaten games, Argentina as well [before the World Cup].

"This is something we have to aim for. We can't just start with that once the tournament starts. We should start that in March. 

"We have to win our games, gain self-confidence and gain some self-understanding for our processes. Then we have to also bring that to the pitch and be able to rely on that."

Matthijs de Ligt is hoping Bayern Munich land their goalkeeper target as they chase Yann Sommer to plug the gap left by injured captain Manuel Neuer.

Defender De Ligt said it "would be nice" to have a new number one in place as 10-in-a-row German champions Bayern prepare for a fresh trophy push in the second half of the season.

Neuer's broken leg, which he suffered during a skiing accident, has thrown a curveball Bayern's way, with the club unexpectedly having to consider the goalkeeping position.

Swiss shot-stopper Sommer, 34, is out of contract at the end of June. He has keen admirers at Bayern, but Borussia Monchengladbach sporting director Roland Virkus indicated his club were not willing to negotiate a sale.

Bayern head coach Julian Nagelsmann hinted that was perhaps posturing on Gladbach's behalf, and three weeks remain in the transfer window to get a deal done.

Asked about the Sommer situation, De Ligt said on Tuesday: "It's difficult for me to say. Manuel is now out for half a year, and of course that's not good for the club.

"But it's not my job to say which goalkeeper we should buy. It would be nice to have a new goalkeeper on the pitch, but I can't influence that."

Bayern have Neuer's understudy Sven Ulreich as an option, but they look certain to bring in a goalkeeper before the window closes, whether that is Sommer or not.

Away with Bayern this week at a Doha training camp, De Ligt is delighted Bayern have brought in his Netherlands team-mate Daley Blind, following the defender's release by Ajax.

Blind arrived on a free transfer last week, in a surprise move that De Ligt is convinced can prove a shrewd piece of business for the Bundesliga leaders.

The 32-year-old Blind played at the World Cup for his country, and De Ligt said: "He's a very good player. With his experience, he can have very good games for us and help us."

Julian Nagelsmann is not worried by Borussia Monchengladbach's declaration that Yann Sommer is not for sale.

Bundesliga leaders Bayern Munich have a goalkeeping conundrum to solve ahead of the season's resumption later this month, after Manuel Neuer suffered a broken leg during a skiing accident.

Sommer, who is out of contract in June, has been touted as a candidate to be drafted in to fill Neuer's void, though Gladbach's sporting director Roland Virkus made it clear that the club were not willing to negotiate a sale.

Nagelsmann is not concerned, however, as he feels the comments are part and parcel of the mid-season window.

"I didn't faint at the headline," he said in a press conference when asked about Virkus' comments.

"If he had said the door was open, his board would also have asked him, 'is everything okay with you?' You have to keep your poker face."

Should a move for Sommer not materialise, another option for Bayern would be to recall Alexander Nubel from his loan at Monaco, though Nagelsmann claimed he has not spoken to the 26-year-old.

"I've never really had contact with him. He was already gone when I came, so he was never really my player," he explained.

"I know him as a goalkeeper, but not as a person. At the very beginning we texted, but that was a long time ago. It wouldn't do him much good if I picked up the phone."

Should a new addition not arrive in January, Nagelsmann is happy to call on long-time back-up goalkeeper Sven Ulreich.

Nagelsmann said: "Ulreich played some great games in the first half of the season. He was very solid. That is also the case in training.

"He had a small mistake. Ulle is very relaxed and has known his role for years."

Bayern resume their push for an 11th consecutive Bundesliga title on January 20 against RB Leipzig.

Julian Nagelsmann has elected against discussing Germany's poor World Cup with his Bayern Munich players.

Seven Bayern players featured in Germany's World Cup squad, as Hansi Flick's side failed to progress from the group stage in Qatar.

A defeat to Japan in their Group E opener was followed by a 1-1 draw with Spain, and a 4-2 victory over Costa Rica was not enough to send Germany through.

It is the second successive World Cup that Germany have failed to make the knockout stage, but Nagelsmann – who succeeded Flick at Bayern and has taken his squad to Doha for a training camp – does not believe it is his job to discuss the tournament with his players.

""I thought a lot about how we would address it during the break. I decided on very little," he told reporters.

"The players have the opportunity to come to me. I deliberately left them alone.

"I'm not much of a comforter. It's always a matter of choice. I can talk for half an hour about the bad, sad World Cup. Or I just leave it out.

"Focus on what they can influence – in the present and in the future. I tried to limit myself to that."

Indeed, Nagelsmann hopes the Bayern players instead turn their disappointment into motivation for the rest of the season.

"I can imagine what it means when you are eliminated from a World Cup," he said.

"But sometimes it's night, then it's usually day again. It's day now and there's a lot of light.

"You have it in your own hands to be more successful than you were at the World Cup.

"We, as the coaching staff, need to create the foundation for the players to perform at their best.

"Frustration and disappointment can also be the biggest motivating factor. I sense they are in a good place, they're training well and are fit."

While Thomas Muller, Joshua Kimmich and the rest of Bayern's Germany players endured a difficult World Cup, Dayot Upamecano established himself as a key part of France's defence.

Upamecano made a spectacular block as France drew 3-3 with Argentina in a thrilling final, only for Les Bleus to lose on penalties, but Nagelsmann has been impressed with the 24-year-old's development over the course of the campaign.

"Upamecano has been solid, as he was in the first half of the season, when he developed well," Nagelsmann said.

"He was also on top form in training. He had a good World Cup and he was one of the best defenders. We need him in top form."

Daley Blind revealed his shock move to Bayern Munich has received the backing of Louis van Gaal and Erik ten Hag.

Former Netherlands boss Van Gaal, who stepped down after the World Cup, is a former Bayern head coach, while Manchester United manager Ten Hag previously had a spell in charge of Bayern's reserve team.

Both think Blind has made a smart move by joining the German champions in a step that few saw coming.

The 99-cap Netherlands defender had been heavily linked with Royal Antwerp, but he jumped at the chance to join Bundesliga leaders Bayern, who are chasing an 11th consecutive league title.

Blind has committed to a six-month contract, with the 32-year-old adding the Bavarian giants to his illustrious list of clubs, having also had a four-year stint at United that ended in 2018.

Asked about the influence on the deal of Van Gaal and Ten Hag, who was his former coach at Ajax, Blind said: "I did not speak to them before. Everything went real quick.

"They messaged me after and told me it was a great step, a great opportunity. They were really happy and wished me all the luck."

Speaking at his presentation in Doha on Saturday, Blind refused to go into the reported falling-out with Ajax coach Alfred Schreuder that preceded him being cut free, six months before the end of his contract.

"There is a lot of news lately about Ajax and me, but I don't think is the right moment to talk about that," he said.

Blind is eager to fight for a place in the Bayern team, aware he will be "maybe not a first choice" initially.

His hope is that there will be the chance to extend his short-term deal, but Blind veered clear of looking too far into the future.

"We'll see what happens," he said. "I'll enjoy the moment for now and see what happens after."

Bayern sporting director Hasan Salihamidzic revealed talks with Blind happened prior to his Ajax exit being announced on December 27.

"Before Christmas we got in touch with him and he showed us straight away this would be his first option," Salihamidzic said.

"We got along very well straightaway and had a good feeling for each other.

"He's an asset for us. We know he's a great player so we hope we can win a few titles together."

Bayern Munich ruled out rushing through a deal for a new goalkeeper as Yann Sommer emerged as a prime target to replace the injured Manuel Neuer.

The 34-year-old Sommer has a contract with Borussia Monchengladbach that runs to the end of this season.

Bayern are weighing up a bid before the January transfer window closes, but they are away in Doha at a training camp for now, so nothing appears imminent.

Sporting director Hasan Salihamidzic spoke at a press conference in the Qatari city on Saturday, where he said efforts were under way to resolve the problem that arose when Neuer suffered a broken leg on a post-World Cup skiing holiday.

Having confirmed Bayern's interest in Switzerland international Sommer on Friday, Salihamidzic has now stressed a deal is not yet in place.

"As I said yesterday, I don't like to talk about other clubs' players," said the former Bayern defender. "The topic of the goalkeeper is of course one where we're thinking about it, but we're working on everything.

"Of course, Manuel's injury is a big blow for us. We're going to continue our work, check options, and then make a decision.

"We have until January 31 and until then we'll either do something or not."

The prospect of the goalkeeper issue going to the wire still appears unlikely, given Bayern resume their Bundesliga campaign on January 20 after the extended winter break.

Coach Julian Nagelsmann would ideally want the situation resolved by then, with there being seemingly little prospect of Alexander Nubel returning from his loan at Monaco.

Nubel has indicated a reluctance to come back, having become a regular in the Monaco team, and Salihamidzic says Bayern are aware of his stance.

"We have had very good communication between us, him and his management. We know exactly what the situation is," said the sporting director.

Bayern will be without defender Noussair Mazraoui for several weeks after announcing on Friday that medical tests had showed up an inflammation issue relating to his heart.

The Morocco international tested positive for COVID-19 at the World Cup, before recovering in time to face France in the semi-finals.

Subsequent tests have shown Mazraoui has a mild inflammation of the pericardium, which is the fluid-filled fibrous sac surrounding the heart.

Salihamidzic said it was unclear whether Mazraoui had been brought back too soon by Morocco.

"It's hard to tell if it was too early or not. He talked to [Morocco] medical staff, he talked to our medical staff, and he had tests. The tests were okay," Salihamidzic said.

"We don't know how it is with post-COVID. It's quite a blow for us that we have to be without him now.

"We'll talk about why this has happened to us. He's an important player for us, so we'll have to try to replace him.

"Of course he will be able to take all the time that he needs to recover. We'll have a test every week and see how he feels from week to week, but for now we're without him."

Bayern Munich defender Noussair Mazraoui faces a period on the sidelines after medical tests showed up an inflammation issue relating to his heart.

The Morocco international tested positive for COVID-19 at the World Cup, Bayern said on Friday.

He returned to the team for the Qatar 2022 semi-final against France after missing the last-eight clash with Portugal, but subsequent tests have shown Mazraoui has a mild inflammation of the pericardium, which is the fluid-filled fibrous sac surrounding the heart.

Bayern travelled without him on Friday to a training camp in Doha, and the club have not specified a timeframe for Mazraoui's absence from the squad.

Newspaper Bild has reported the 25-year-old former Ajax player could be out of action for four to six weeks. That would make Mazraoui a doubt for the February 14 first leg of Bayern's Champions League last-16 tie against Paris Saint-Germain.

The Bundesliga leaders said in a statement on their website: "Noussair Mazraoui was not able to fly with the Bayern team to Doha on Friday as they prepare for the second half of the season at their training camp.

"The 25-year-old Morocco international tested positive for COVID-19 during the World Cup in December, meaning he missed the quarter-final against Portugal.

"During a follow-up examination in Munich after the World Cup, FC Bayern team doctor Professor Dr Roland Schmidt diagnosed a mild inflammation of the pericardium, which the defender will now cure.

"This means that Mazraoui will not be available to coach Julian Nagelsmann for the time being."

Bayern signed up Dutch defender Daley Blind on Thursday to fortify their squad ahead of the resumption of the Bundesliga after its extended winter break.

The 10-in-a-row German champions return to domestic action against RB Leipzig on January 20.

Midfielder Marcel Sabitzer also missed the beginning of the training camp due to flu, with plans for him to make the trip to Qatar once well.
