Manuel Neuer described Robert Lewandowski as a "machine" after the striker reached 300 Bundesliga goals with a hat-trick in Bayern Munich's 4-0 win over Cologne.

The Poland star broke the deadlock on Saturday as Bayern became the first team in the history of the competition to score in 66 consecutive matches.

After Corentin Tolisso struck a fine second, Lewandowski delivered two more precise finishes following Leroy Sane throughballs to move the leaders six points clear.

The 33-year-old is just the second player in Bundesliga history to reach a treble century of goals, after Gerd Muller, who scored a record 365.

Last season, Lewandowski scored 42 times to break Muller's record for goals in a single Bundesliga season, and he could now have the outright leading tally in his sights.

"After the defeat to Borussia Monchengladbach, it was just important for us to get our first points of the year, and that's what we did," Neuer told Sky Sport.

"We're happy and grateful that we have Robert. He's a machine up front."

There was a curious moment after the match, when Neuer exchanged his shirt for the flat cap of Cologne head coach Steffen Baumgart.

"His cap is legendary!" he said.

The game was Bayern's first since it was confirmed that full-back Alphonso Davies will have to sit out training after being diagnosed with inflammation of the heart.

Coach Julian Nagelsmann said the Canada international will be out of action for at least the next month.

"It could be that it goes away quickly, but it's at least four weeks – and everything is possible for an indefinite amount of time," he said prior to the match.

"If you suffer from something like this, you usually don't notice it. You only notice that you're not 100 per cent when you move.

"[It is important] that we do the examinations meticulously, and that's how we diagnosed it. It's important for him to heal, but it's a shape because Alphonso had just come back."

Bayern Munich defender Alphonso Davies is unable to take part in training due to a mild inflammation of the heart.

The 21-year-old has not featured for Bayern since December 17 after testing positive for COVID-19 earlier this month.

Davies had been due to return to action for the German champions this week, but routine medical checks discovered another medical issue.

Bayern boss Julian Nagelsmann confirmed at a news conference previewing Saturday's trip to Cologne that the Canada international will be out of action indefinitely.

"When we did our follow-up examination we do with every player that has had COVID-19, we detected signs of mild myocarditis, an inflammation of the heart muscle," he said.

"He'll sit out training until further notice. He won't be available, also in the coming weeks. 

"The ultrasound shows this myocarditis isn't so dramatic, but it's a sign of myocarditis. Still, it has to heal and that will definitely take some time."

Davies has started 22 of Bayern's 27 matches this season – only Manuel Neuer (25), Thomas Muller and Robert Lewandowski (both 26) have started more regularly.

He has made 16 appearances in the Bundesliga this term and leads the way in the division for dribbles attempted (97) and completed (61).

Davies' lay-off is also bad news for Canada as they have two crucial World Cup qualifiers at the end of this month.

While the left-back will sit out Bayern's clash with Cologne, Bayern will welcome back six others from last week's shock 2-1 home loss to Borussia Monchengladbach.

But Nagelsmann will not take any risks when it comes to the fitness of Manuel Neuer, Dayot Upamecano, Omar Richards, Leroy Sane, Corentin Tolisso and Tanguy Nianzou 

"None of them are 100 per cent fit," he said. "Some of them had coronavirus symptoms. They're back in the squad, but none except Manu are ready to start or play for long.

Asked about Tolisso's availability, Nagelsmann said: "He had no symptoms and has come back the fittest. We have to see, but he'll be involved."

Leon Goretzka, Kingsley Coman and Lucas Hernandez will miss out this weekend, while Eric Maxim Choupo-Moting and Bouna Sarr are on Africa Cup of Nations duties.

Bayern have won each of their last eight Bundesliga games against Cologne and are unbeaten against them in their last 15 league games (W14 D1).

Steffen Baumgart's sixth-placed side have won their last three league games, however, which is as many as they managed in the previous 14 combined.

Julian Nagelsmann was pleased with his team's efforts despite Bayern Munich losing 2-1 at home to Borussia Monchengladbach in the first Bundesliga game after the winter break.

A superb opener from Robert Lewandowski - who was nominated for the Best FIFA Men's Player 2021 award earlier on Friday - was cancelled out before half-time by Foals duo Florian Neuhaus and Stefan Lainer, with the league leaders unable to respond in the second half.

Bayern were without a number of key players through COVID-19 and injuries, including Manuel Neuer, Lucas Hernandez, Dayot Upamecano, Leon Goretzka, Alphonso Davies, Kingsley Coman and Leroy Sane, but Nagelsmann still believed his team deserved something from the game.

Speaking after the defeat, the 34-year-old told reporters: "We were actually closer to winning than Gladbach were.

"Considering the situation, we did very well in the first 25 minutes, we should have been up by more. The way we conceded the equaliser was complete madness, I don't know why we wanted to do that in the box like that, and then we conceded from another set-piece.

"In the second half we played decently and had lots of chances. Unlike in the cup game, we didn't deserve to lose today."

Although Nagelsmann was still able to name a relatively strong starting line-up, Bayern's bench was practically unrecognisable, filled with youngsters, including the debuting Paul Wanner.

Aged 16 years and 15 days, Wanner's 75th-minute introduction saw him become the second-youngest player in Bundesliga history, behind only Borussia Dortmund's Youssoufa Moukoko (16 years, 1 day), and Nagelsmann was effusive in his praise of the teenager.

"He's an unbelievable talent, very quick and very brave," the former Hoffenheim and RB Leipzig coach said. "He immediately took on [Breel] Embolo and went on dribbling in his first action. Physically he's not bad either. But he has to remain grounded and clear in his head, then the doors will be open for him."

Bayern were thrashed 5-0 by Gladbach in the DFB-Pokal earlier in the season, and Nagelsmann had expressed a desire for revenge ahead of the game, but instead Adi Hutter only increased his impressive record against the young German coach.

Hutter and Nagelsmann have now met eight times as opposition coaches in the Bundesliga, and nobody has won as often in the top flight against Nagelsmann as the Gladbach boss (W4 D3 L1).

The former Eintracht Frankfurt coach praised the intensity of his team, saying after the win: "Huge compliments to the team for coming back like that and getting the win in Munich. When the intensity is high, you have a good chance of winning, and that's what we showed today.

"Of course Bayern could have equalised, but my team played well. They implemented what we trained."

Bayern Munich midfielder Leon Goretzka may require surgery to rectify the troublesome knee injury that has kept him out of action for over a month, according to Die Roten coach Julian Nagelsmann.

The Germany international, who has two goals and two assists in 12 Bundesliga appearances this term, has not taken to the pitch since Bayern’s 3-2 win over rivals Borussia Dortmund on 4th December, in which he managed just over an hour after struggling with a previous knock. 

Speaking ahead of the champions' home match against Borussia Monchengladbach, revealed that a decision on whether he requires surgery is due in the next couple of days.

"It's complicated." Nagelsmann said of the situation. "He [Goretzka] had two good days of training, then we had to decrease the strain [on him]. His physical condition was a lot worse.

"We examined him again and we did an MRI scan, but we couldn't detect anything.

"So, we sent him to another specialist, who will examine him again and decide what we're going to do; whether we can keep treating it conservatively, or if we have to open it up and have a look.

"In the next two days we'll decide what we need to do."

Any long-term absence for the former Schalke midfielder, who has won three Bundesliga titles and one Champions League since arriving at the Allianz Arena in 2018, would be a severe blow to the hopes of Nagelsmann's side, whose preparations for their return to Bundesliga action have been hampered by a number of players contracting COVID-19. 

The former Hoffenheim coach did not hide his frustration at Goretzka's situation.

"What is clear is that we can't keep going this way. The situation is bad for him, and bad for the club.

"Of course, we all want him to play, and he wants to play, but that's not possible. We have to think about a couple of new paths that we could go down."

Bayern have won their past five Bundesliga matches to open up a nine-point lead at the summit, but will still be keen for the return of their midfield mainstay, who was named in the Bundesliga team of the season last campaign.

Julian Nagelsmann does not regret giving Bayern Munich's players freedom to enjoy their vacation during the Bundesliga's mid-season break.

German top-flight leaders Bayern are set to face Borussia Monchengladbach on Friday, but currently have nine players who have returned positive COVID-19 test results.

Manuel Neuer, Lucas Hernandez, Dayot Upamecano, Tanguy Nianzou, Omar Richards, Corentin Tolisso, Kingsley Coman, Leroy Sane and Alphonso Davies have all tested positive for the virus.

Eric Maxim Choupo-Moting and Bouna Sarr are with Cameroon and Senegal respectively for the Africa Cup of Nations. Niklas Sule is nursing a back problem, while Leon Goretzka and Josip Stanisic are injured.

Gladbach's sporting director Max Eberl confirmed on Wednesday that Bayern had asked for the game to be postponed. Bundesliga rules allow a team to request a postponement if they have fewer than 16 players, including a goalkeeper, available.

But Nagelsmann, who contracted the virus in 2021, does not believe he should have limited the movements of his players during the recent hiatus in an attempt to curtail the possibility of an outbreak.

"I have a clear opinion about this topic. I'm not a teacher, I'm a coach," Nagelsmann told a news conference.

"Our players are all adults. My players are responsible for their own lives. We have the same rules and recommendations that we've had the last two years.

"You want to remain healthy. There's no option to suggest to a player that he can't go on holiday, if the law doesn't prevent that. There's psychological recovery. If you look at Upamecano, he flew to Senegal to see his family. If I don't let him do that then I can't let another player go 10 miles down the road to see his family.

"Every employee was allowed to go on holiday. You can't tell a player not to go, to stay home. With Omar Richards, once we found out that England was a high-risk area we got him back from England. 

"I don't know why we have more infected players than others. It's unfortunate, but the players have the same rules that have worked very well. There are other clubs that don't do PCR tests, they do fast tests that aren't as sensitive. So there's a couple of elements, we have to make the best of the situation.

"I was very happy with the players, the U23s and U19s players that joined us. I am not the type of coach to complain. We can discuss if these rules make sense. I went out for a meal and was infected. I rarely go out. I went out once and got coronavirus. It happens, I don't know exactly why."

Asked if the game would be going ahead at all, Nagelsmann said: "I can't answer that with 100 per cent accuracy. My job, and the job of the players, is to prepare as if it is going to take place.

"That's what we're operating on, that's what we're expecting. We've prepared all week for this game to take place. 

"It's a challenging situation, but as a coach it's an interesting challenge, you have to adapt, change your tactics to turn your problem into a strength."

One player who will return is Joshua Kimmich, who has not played since November after contracting coronavirus.

Kimmich's recovery was hampered by a lung issue but Nagelsmann confirmed the midfielder is fit to feature.

"Joshua is making a very good impression. He's very happy, his physical condition is outstanding," he said.

"If everyone was here he'd probably play, now it's clear he's going to play anyway because he has to. He deserves to play, we're all happy that he's back and he will play tomorrow."

Kimmich had initially declined the vaccine while he waited for more research on possible side effects, though confirmed in December that he had changed his mind and would take up the option.

Asked if Kimmich had received the vaccine, Nagelsmann said: "I can't say, I don't want to, that's a private matter. It's Joshua's responsibility to talk about that."

Julian Nagelsmann expressed his satisfaction with Bayern Munich as the Bavarians head into the mid-season Bundesliga break top of the table.

Bayern cruised to a 4-0 victory on Friday over Wolfsburg, with Thomas Muller – who was making his 400th league appearance for the reigning champions – scoring the first and assisting Dayot Upamecano's second.

Leroy Sane soon added a curling third before Robert Lewandowski sealed victory as the Poland striker netted his 43rd top-flight goal of 2021, surpassing Gerd Muller's long-standing calendar-year record for Bundesliga goals, set in 1972 (42).

Bayern boast a nine-point lead over second-placed Borussia Dortmund, who play their game in hand against Hertha Berlin on Saturday, and former RB Leipzig head coach Nagelsmann has been pleased with his side's efforts to date.

In the three points-for-a-win era, Bayern have won the title in 14 of the 15 seasons they have topped the league at the halfway point.

"I'm very satisfied with our first half of the season," Nagelsmann told reporters. "It's not simple to score this many goals against such a compact defence. 

"We had very good control and pressed even better in the second half. The key was counter-pressing: we won the ball high and closed all gaps.

"I'm very happy with the performance. We played a lot of games recently; the first half was more difficult. The initial phase was good, then we slowed down a bit. Then [Wout] Weghorst had a chance, we were lucky, or we had a good goalkeeper, maybe a mixture of both.

"The way we played in the second half was great. The goals were outstanding."

On Lewandowski's landmark strike, Nagelsmann added: "I was very happy that he scored. It was a wonderful goal – Lewy played a great game."

Nagelsmann also reserved praise for Upamecano, who made a staggering 103 passes in Wolfsburg's half – a game-leading figure – while also leading Bayern for tackles made (five) and possession won (14 times).

"He scored a goal, which is great," the Bayern head coach continued. "We know how important it is to have goalscoring defenders when the opponent sits very deep. 

"He was very focused today. Overall, he's having a good season, except for a couple of games. We shouldn't forget he's young, he isn't 28."

Julian Nagelsmann hailed the "outstanding" Serge Gnabry after he scored a hat-trick in Bayern Munich's 5-0 thrashing of Stuttgart.

Gnabry marked his first start for almost a month with a superb display, helping himself to a treble and laying on the other two goals for Robert Lewandowski in the city where he was born.

The Germany forward gave Bayern a 1-0 half-time lead and they ran riot after the break, scoring three times in the space of five minutes behind closed doors at Mercedes-Benz Arena on Tuesday.

Gnabry was directly involved in five goals in a competitive match for only the second time in his career, with the only previous instance coming in the 7-2 win at Tottenham in October 2019 - when he scored four and provided one assist

Victory in Julian Nagelsmann's 200th Bundesliga match as a head coach put the champions nine points clear at the top of the table.

Nagelsmann lauded Gnabry, who has had to bide his time to force his way back into the team after a spell in quarantine and has also been hampered by an injury.

The Bayern head coach said: "He is an outstanding player who is currently struggling with his back and therefore maybe gets a tad less minutes than he deserves.

"He did very, very well today."

It was another devastating performance from the Bavarian giants, but there was concern when they lost Kingsley Coman to an injury in the first half

Nagelsmann said of the France winger: "We don't have an exact diagnosis for him yet. It's a muscular issue. We're hoping that it's nothing serious."

Lewandowski's double took him level with the great Gerd Muller on a record 41 goals in a calendar year in the German top flight.

Bayern Munich head coach Julian Nagelsmann is hopeful Joshua Kimmich's declaration that he is ready to take a COVID-19 vaccine will draw a line under the matter.

Kimmich made headlines in October when he explained he was not willing to receive his first dose due to what he perceived as a lack of research into possible long-term effects.

The 26-year-old has not featured for Bayern since November 6 after twice being forced to isolate due to being a close contact of someone who tested positive for coronavirus.

He was then infected with COVID-19 himself and was last week ruled out until 2022 due to an issue with his lungs.

Kimmich confirmed in an interview with ZDF on Sunday that he is now in a position where he feels ready to get vaccinated.

Nagelsmann, who was himself struck down by the illness, is pleased with Kimmich's announcement but insisted he did not sway the midfielder's decision.

"I think it's good that he faced the media. A lot has been reported about him in the last few weeks," Nagelsmann said on Monday. 

"I gave him my opinion, but in the end his conviction was a result of talks with other people at the club. I rather try to work on the pitch."

Nagelsmann, who has been regularly questioned on the topic over the past two months, added: "I think it's funny I'm still being asked! 

"When the year 2021 comes to an end, I hope that we will be able to deal with the pandemic subject more briefly because we can master the situation."

Bayern will be without Kimmich for their final two Bundesliga games of the year, while Jamal Musiala is also doubtful to face Stuttgart on Tuesday and Wolfsburg next weekend.

Musiala has scored in Bayern's last two games, including the decisive strike to see off Mainz 2-1 on Saturday, but a broken hand could keep him out of action until 2022.

"That depends on the pain," Nagelsmann said ahead of the trip to Stuttgart. "He has a splint and could theoretically play, but it's a pain issue. 

"We'll see how he moves today. We'll have to wait a few days and take another X-ray to see how to proceed with the treatment, whether it will be surgical or conservative."

Nagelsmann confirmed Leon Goretzka and Corentin Tolisso are also fitness doubts for Tuesday, but Marcel Sabitzer has returned to training and may be part of the squad.

Bayern have won 66 of their 104 Bundesliga matches against Stuttgart – no other team in Bundesliga history has won so often against a single opponent.  

The Bavarian giants have won 17 of their last 18 league meetings with Stuttgart, with the only exception being a 4-1 loss in May 2018.

Pellegrino Matarazzo's side have taken seven points from their last three games, however, and Nagelsmann is not anticipating an easy game in midweek.

"In terms of the table, they are not quite as good as they were last year," he said. "But it is incredibly difficult to prepare to face them.

"Their coach, who I know well, is a mathematician and that's how he approaches games. You cannot prepare for the way they will set up."

A draw for Bayern at Mercedes-Benz-Arena will ensure they sit top of the Bundesliga at the halfway point for the 15th time in the 16 seasons since the introduction of three points for a win.

Julian Nagelsmann felt Bayern Munich made life difficult for themselves after the reigning Bundesliga champions defeated Mainz on Saturday.

Bayern fell behind to Karim Onisiwo's first-half strike before Kingsley Coman levelled things up at the Allianz Arena.

Jamal Musiala then delivered the decisive strike to help Nagelsmann to his 100th win as a manager in the Bundesliga.

At just 34 years and 141 days old, Nagelsmann is the youngest coach in the history of the German top flight to reach the 100-win milestone, with his first and his 100th victories both coming against Mainz.

But the former RB Leipzig head coach was disappointed with Bayern's first-half performance as he felt his side caused their own problems, though he was satisfied with their response in the next 45 minutes.

"The win was tough because Mainz are doing very well this season," Nagelsmann told reporters. "But we rather made it difficult for ourselves. We started well, I had a great feeling – suddenly the momentum was gone and we played very slowly.

"In the second half we were really sharp and put in a lot of power and intensity from the first to the 88th minute. That was a very good reaction by the team."

Nagelsmann also reserved special praise for Jamal Musiala, who operated in a deeper midfield role in the absence of Joshua Kimmich.

Musiala scored from his one effort on target and also attempted 10 dribbles, a tally only bettered by team-mate Kingsley Coman (12).

"He's left his 'Bambi' status," Nagelsmann added on the versatile Musiala. "At some point you grow out of your talent status. 

"He should keep this street football gene, but he doesn't have to become Gennaro Gattuso. Defensively, it's all about being reliable."

Leaders Bayern move six points clear after Borussia Dortmund were held to a 1-1 draw by Bochum, while Nagelsmann's side next travel to Stuttgart on Tuesday.

Julian Nagelsmann won his 100th Bundesliga game as Jamal Musiala's strike completed a 2-1 comeback victory over Mainz.

Perhaps suffering a hangover from their Champions League win over Barcelona, Bayern – without a number of key players – were far from their slick best on Saturday.

But the champions ultimately had too much quality, with Musiala, playing in an unfamiliar central midfield role, slotting in a 74th-minute winner.

Kingsley Coman had equalised to cancel out Karim Onisiwo's header, with Mainz unable to withstand the pressure as Nagelsmann moved onto a century of league wins in his 199th top-flight game as a coach.

More often a provider, Alphonso Davies had two chances to put Bayern ahead inside 10 minutes, but he failed to put a close-range volley on target before a deflected effort hit the post.

Yet Bayern's ominous start failed to produce a goal. Indeed, Mainz were unfortunate not to have a penalty when Dayot Upamecano barged into Jae-Sung Lee.

Bayern avoided punishment, but Mainz kept up the pressure and had the lead in the 22nd minute – Onisiwo heading in from Jonathan Burkardt's cross.

Thomas Muller saw an acrobatic attempt deflected over before Alexander Hack kept Coman at bay. It was the latter who got Bayern level in the 53rd minute.

Corentin Tolisso's well weighted pass caught Mainz napping, with Coman's excellent touch setting him up for a strike that squirmed under Robert Zentner.

Coman latched onto another fantastic pass from deep soon after, this time cutting in from the left before drilling an effort just over.

Bayern's winner came with 17 minutes remaining, though, with teenager Musiala taking a sublime touch to create space on the edge of the box before finding the bottom-left corner with unerring accuracy.

Robert Lewandowski has continued with business as usual despite disappointment at the 2021 Ballon d'Or awards, according to Bayern Munich head coach Julian Nagelsmann.

Lewandowski had to settle for second place and an inaugural Striker of the Year accolade at the France Football award ceremony, with Lionel Messi collecting a record-extending seventh crown.

The Bayern striker may have felt hard done by, given he has scored 14 more times than any other player in Europe's top five leagues in 2021, with 55 goals across all competitions to his name so far.

The Poland international also missed out last year due to the coronavirus-enforced cancellation of the 2020 Ballon d'Or, which he was favourite for after breaking Gerd Muller's long-standing Bundesliga record following 41 goals in 29 league games last term.

But Nagelsmann insisted that Lewandowski – who again leads Europe's top five leagues with 27 goals this term across all competitions, seven more than second-placed Mohamed Salah – has not let the Ballon d'Or snub impact his performances.

"I haven't noticed a big change in terms of hunger for goals, regardless of the Ballon d'Or decision or new records," Nagelsmann, whose side face Mainz on Saturday, told reporters at his pre-match news conference.

"I think he was in an incredibly good mood lately with very good body language. He also does his job defensively very neatly. I think he just wants to be successful with FC Bayern."

Bayern, inspired by the likes of Lewandowski and Serge Gnabry, sit four points clear of Borussia Dortmund at the top of the Bundesliga as the reigning champions prepare to host Mainz.

Nagelsmann is also eyeing a landmark of his own, with a potential 100th Bundesliga win awaiting him in just his 199th game as a top-flight boss.

Should he do so, he will become the fastest to a century in the German top flight but the former RB Leipzig head coach claimed he did not even know he was approaching a milestone as he praised his team's recent efforts.

"Thanks for the memory, I didn't even know that," he added. "That's a nice number, I'm happy.

"The players are in a good mood, I think. The atmosphere is also good on the pitch and in the dressing room. 

"I think we have mastered the difficult autumn quite well so far, even with the many injuries and failures. We want to win the rest of the games and keep the gap to Dortmund in the league. We will drive ahead with full speed."

Nagelsmann, however, will be without Joshua Kimmich, who will miss the remainder of 2021 with a lung problem as he continues to recover from coronavirus.

But the Bayern head coach defended his player, who is yet to be vaccinated for COVID-19, after suggestions Kimmich was causing problems.

"Basically, it's always good if you ask him that yourself," he continued. "Of course, as a thoroughbred athlete, he always wants to be on the pitch, especially because he's always been fit. 

"You have to allow opinions here in Germany. He has made his decision, you have to accept it."

Julian Nagelsmann claims Jude Bellingham tarnished Bayern Munich's Klassiker win over Borussia Dortmund with his costly outburst against the match referee.

Bellingham was unhappy after Dortmund were denied two spot-kicks in Saturday's action-packed Bundesliga clash prior to Mats Hummels being penalised for handball.

Robert Lewandowski converted the resulting penalty to earn Bayern a 3-2 win, leading Dortmund teenager Bellingham to question the integrity of referee Felix Zwayer in his post-game interview.

The England international appeared to allude to a six-month ban handed to Zwayer following a 2005 match-fixing scandal, which centred around fellow official Robert Hoyzer.

Hoyzer was found to have fixed 2. Bundesliga matches in 2004-05. One of those involved Zwayer operating as an assistant, with the allegation he took a €300 bribe. Zwayer strenuously denied any such wrongdoing in the course of that investigation.

Bellingham's comments are reportedly being examined by police, while the German Football Association (DFB) has fined the youngster €40,000.

As the fallout continues from Bayern's win, which moved them four points clear at the summit, Nagelsmann gave his view on the refereeing decisions and Bellingham's remarks.

"Those comments tarnished the game a bit," Bayern head coach Nagelsmann said at a news conference ahead of Wednesday's Champions League clash with Barcelona.

"I can understand the discussions. But the incident involving Marco Reus couldn't have resulted in a penalty because there was an offside.

"I wouldn't have complained about the penalty for us if it hadn't been given. I can understand from Dortmund's point of view."

Bayern now switch focus to the visit of Barca to the Allianz Arena, with the game to be held behind closed doors due to rising coronavirus cases in Bavaria.

The German giants have won each of their last three meetings with Barcelona, which is the longest run of wins by a team against Barca in their European Cup and Champions League history.

Nagelsmann's side are already assured of top spot in Group E, while the visitors may need to win if they are to progress, depending on how Benfica get on against Dynamo Kiev.

Despite Barcelona enduring a trying time on and off the field in recent times, Nagelsmann insists it is only a matter of time before the LaLiga heavyweights turn things around.

"I think they are still an extremely attractive club for players and fans," Nagelsmann said. "The financial figures are known. If that hovers over you, you will be a little inhibited.

"In a successful era you may become lazy and need too long for decisions. Then you seldom think about what happens when things go bad.

"The spitting out of talent has been a bit lacking, but that will only come again. Obviously they are making ends meet and still have a good squad.

"For me, Frenkie de Jong is one of the best midfielders in the world. They still have world-class players. They are under pressure in the table and have to win. They will give everything to make this a good game."

Bayern have won all five of their group matches, scoring a combined 19 goals and conceding three.

At home, they have scored five goals in each of their two Champions League games so far this term and have netted at least twice in each of their last 11 home matches in the competition.

The Bavarians will remain without Leon Goretzka on Wednesday due to injury, despite the midfielder returning to training, while Serge Gnabry is out with an adductor issue.

Despite having little to play for on the face of it, Nagelsmann intends to name a strong side to face Barca.

"We'll play our best available team," he said. "Benfica don't have to worry! We are going for six wins from six and that is a worthwhile goal."

Borussia Dortmund head coach Marco Rose has confirmed Erling Haaland is not fit enough to play a full part in this weekend's key Klassiker clash with Bayern Munich.

Haaland scored just seven minutes into his comeback from a six-week injury lay-off in last Saturday's 3-1 win over Wolfsburg.

That was the Norway striker's 50th Bundesliga goal, reaching the landmark in just 50 matches and becoming the youngest ever player to do so at 21 years and four months.

However, with just those 17 minutes of football to his name since sustaining a hip injury on October 19, Haaland will not be considered to play the whole game against Bayern.

"Erling himself knows his situation," Rose said at Friday's pre-match news conference. "He has had a good week of training behind him. 

"But we all know that we have to be careful a little longer. He will certainly not be ready for 90 minutes, so we will have to see how long he can go."

Haaland has averaged 1.12 goals per 90 minutes played in Germany's top flight, scoring 40 with his left foot, six with his right and four headers.

Since making his Dortmund bow in January last year, only Robert Lewandowski (70 goals in 56 games) has scored more Bundesliga goals than the ex-Salzburg man.

Indeed, no player in Europe's top five leagues has scored more goals in all competitions this season than Bayern striker Lewandowski's 25.

Despite his continued brilliance in front of goal, Lewandowski finished second to record-extending seven-time winner Lionel Messi at Monday's Ballon d'Or ceremony.

Rather than feel sorry for himself, however, Bayern boss Julian Nagelsmann is backing Lewandowski to be extra fired up against Dortmund on Saturday.

"I've already said that he's in great shape and it's not impossible that he could win this thing again," Nagelsmann said at his pre-match news conference. 

"He can't change the past. He's working every day on the present and the future gets created with his work in the present. I think it could be possible that he wins it someday.

"And I'm sure that, when you look at his current numbers without mathematical talent like me, it looks good for this season.  

"Therefore, I believe that he can do it and that those who vote will vote for him next year and say that he deserves the Ballon d'Or.

"It is important to accept this disappointment but also to take energy and motivation for other big performances. And I'm confident that he has this drive."

Against no team has Lewandowski scored more goals in all competitions than against former side Dortmund (24, level with his record against Wolfsburg).

Dortmund have lost their past six competitive matches against Bayern, but they enter this contest with six wins in their previous seven leagues games and are just a point behind Bayern.

Asked how his side go about beating reigning champions and current pacesetters Bayern at Signal Iduna Park, Rose said: "We need to play well in every department.

"I believe that Bayern have a clear structure with the ball and develop a goal risk from it with a lot of force. It is difficult to grasp. 

"It will be important to eliminate the offensive quality around Lewandowski and the wingers and to keep Munich out of the penalty area as much as possible."

Julian Nagelsmann believes Bayern Munich are ready for Der Klassiker after digging deep for a 1-0 home win over Arminia Bielefeld.

Bayern's clash with Bundesliga title rivals Borussia Dortmund is coming up next Saturday, with the great rivals sitting first and second in the German top flight.

Dortmund briefly occupied top spot on Saturday after a 3-1 win over Wolfsburg, in which Erling Haaland returned from injury with a goal.

But they were nudged off the summit later in the day when Leroy Sane's 71st-minute strike earned a depleted Bayern three valuable points. Eight days previously, Bayern were beaten by Augsburg, so a league win of any sort this time was to be welcomed.

Nagelsmann's squad has been hit hard by COVID-19 cases, but the head coach saw enough from the team he fielded against Arminia to be optimistic about the tussle with Dortmund.

The Bayern boss said: "I am very satisfied. It was a step forward after the Augsburg game.

"We had enough chances to win the game. We gave away a few chances in the second half. Dortmund won, so we were under a bit of pressure. It's a deserved victory. We don't always have to score three, four or five goals. One is enough.

"Overall, we defended well. Such games are important. If you lose those games, then it's not enough to just win games like next week.

"We are now heading to Dortmund as championship leaders and full of anticipation."

Sane's goal was Bayern's 102nd in the league this calendar year – a Bundesliga record, beating Cologne's mark from 1977.

Thomas Muller made his 396th Bundesliga appearance for Bayern, matching the great Franz Beckenbauer's total and going sixth on the club's all-time list, led by Sepp Maier (473).

Asked how many more games he could play, midfielder Muller told Sky Deutschland: "We'll see. If I stay fresh and fit, and well enough, then something is still possible. That is just a nice statistic, it simply shows the path I have already taken.

"But I am looking forward more to the road still ahead of me, which is certainly a bit shorter in comparison."

Julian Nagelsmann would like Ralf Rangnick to be handed a long-term role at Manchester United amid widespread reports the experienced coach is to become the club's interim manager.

Rangnick, 63, only took over as Lokomotiv Moscow's head of sports and development earlier this year following an eight-season spell across various roles at RB Leipzig.

But the former Stuttgart and Schalke coach, who is credited for influencing some of football's brightest minds, appears set to join United as interim manager following Ole Gunnar Solskjaer's departure.

Nagelsmann and Rangnick's careers crossed paths at Leipzig between 2019 and 2021, with the latter acting as head of sport and development for RedBullGMBH following his director of football role at both Red Bull Salzburg and the Bundesliga side.

Now Bayern Munich head coach Nagelsmann, whose high-pressing philosophy largely resembles Rangnick's preferred approach, believes his compatriot will be a hit at United.

Asked about his mentor's potential appointment at Old Trafford, Nagelsmann said: "I think it's cool. I also wrote to him. I think I wrote 'cool'.

"I'm happy for him. He's an excellent trainer."

While the 34-year-old was pleased with the Red Devils' reported move, he explained he would like to see Rangnick offered a longer deal as United are set to search for a permanent solution at the end of the season.

"I would like him to be a coach longer than until the summer," he continued. "From Man United's point of view, congratulations."

Reports have suggested United will look to appoint Rangnick on a consultancy basis after his time as interim boss is up.

Mauricio Pochettino has been touted as United's preferred option to take over next year, though Paris Saint-Germain have insisted the Argentine is staying put.

United face Chelsea on Sunday, with Rangnick's appointment expected to have gone through by that stage. However, Michael Carrick is set to be in charge for the trip to Stamford Bridge.
