Bayern Munich returned to winnings ways after reaching the DFB-Pokal quarter-finals as Eric Choupo-Moting scored one and assisted another in a 4-0 victory at Mainz.

Julian Nagelsmann's side are just a point clear at the Bundesliga summit after three successive 1-1 draws, but they ended their winless run with a dominant showing at MEWA Arena on Wednesday.

Manchester City loanee Joao Cancelo assisted Choupo-Moting's opener just 17 minutes into his debut, before the striker teed up Leroy Sane on the stroke of half-time after Jamal Musiala's 30th-minute strike.

Substitute Alphonso Davies sealed the victory in the second half prior to Alexander Hack being dismissed late on, as Bayern picked up a first win of 2023 to remain on course for a first DFB-Pokal triumph since 2020.

Mainz did not heed the early warning signs against a dominant Bayern and were punished as Choupo-Moting expertly volleyed Cancelo's right-wing centre past Finn Dahmen at the far post.

Musiala doubled the visitors' advantage with a pinpoint left-footed finish into the bottom-right corner after Thomas Muller's delicate pass.

Joshua Kimmich then curled a free-kick from a tight angle against the left post, before Sane calmly finished from Choupo-Moting's throughball as a rampant Bayern ran riot in the first half.

Hack cleared Muller's deflected attempt off the line after the interval, while Anthony Caci whipped a rare Mainz chance narrowly wide at the other end.

Davies nodded Kimmich's right-wing cross past Dahmen for Bayern's fourth, before Hack was shown a second yellow card for a needless foul on Musiala as Bayern eased to victory.

Jurgen Klopp reaches 1,000 games as a head coach and manager on Saturday when Liverpool tackle Chelsea, and it has been quite a ride.

From a relegation battle with Mainz in the German second division to the heights of Champions League glory with Liverpool, Klopp has achieved more than anyone expected of a man whose playing career was distinctly modest.

It would be stretching it to say the signs were there from day one, but they were certainly there from day two.

Klopp was named as an interim replacement for Eckhard Krautzun when Mainz decided on a change of leader on February 27, 2001.

One day later, Klopp made his debut as a coach in the second tier of the Bundesliga. He had been a player in the team until that point, but this marked the beginning of a new chapter.

Club president Harald Strutz, quoted in the Rheinische Post at the time, voiced the suggestion the interim boss could stake a claim for the full-time job.

"Maybe that will be a permanent solution," Strutz said, presciently.

Midfielder Christof Babatz, who would be a significant figure in Mainz's rise to the Bundesliga under Klopp, then said after the first game resulted in a 1-0 win over Duisburg: "The coach teased that certain something out of us."

And so began the story of Klopp's touchline career, one centred on teasing out the very best from the talent at his disposal, nurturing prospects into polished performers, and tallying trophies along the way. From Mainz, to Borussia Dortmund, and eventually to Liverpool, Klopp has delivered on that initial leap of faith.

There have been league titles, cup triumphs and big European final nights with Liverpool and Dortmund, plus promotion and even a relegation during his formative Mainz days.

Here, Stats Perform looks at those first 999 games, as Opta data shows some essential numbers behind one of the 21st century's great coaching careers.

Pep, Howe, Hecking and Magath – Klopp's rivalries

Klopp has faced Pep Guardiola more than any other rival manager, going head-to-head with the Catalan 27 times across their careers.

There have been notable defeats along the way, including the 2014 DFB-Pokal final, when Klopp's Dortmund went down 2-0 to Guardiola's Bayern, and the 5-0 and 4-0 thrashings meted out by Manchester City to Liverpool in September 2017 and July 2020, both of which rank among the top nine heaviest defeats Klopp has had to stomach.

However, Klopp has the overall upper hand across their meetings, winning 11, drawing seven and losing nine of those games.

He has faced only one other boss more than 20 times: German Dieter Hecking, against whom Klopp pitted his wits 21 times, winning 11, drawing five and losing five. Hecking bossed Lubeck, Alemannia Aachen, Hannover, Nurnberg and Wolfsburg during Klopp's time in the German leagues.

Klopp certainly has a happy record against Newcastle United's former Bournemouth boss Eddie Howe, achieving 11 wins from their 13 meetings.

This shows the most wins Klopp has had against any boss is 11, against Guardiola, Hecking and Howe, while it can be revealed the team he has beaten the most are Freiburg (13 times), followed by Crystal Palace, Nurnberg and Arsenal (all 12).

His real nemesis appears to have been Felix Magath, the former Stuttgart, Bayern, Wolfsburg and Schalke coach. In 14 games against Magath teams, Klopp won only three times, losing eight.

Bayern have had the most wins against Klopp, with 16. No other team have reached double figures, with Hamburg, Schalke and Wolfsburg (all nine) next on the list.

The milestones, the biggest and the best... and the games he'd rather forget

Klopp won that first match of his career against Duisburg, and to date he has never lost on each 100th game on his way towards 1,000 as a boss.

There have been wins against the way against Bochum (200th game), Werder Bremen (300th), his old club Mainz (400th), Freiburg (500th) and Southampton (600th), and draws on his 700th, 800th and 900th games, against Newcastle, Chelsea and Real Madrid, respectively. Klopp's 100th game was also a draw, against Unterhaching with Mainz.

His biggest win was the 9-0 trouncing that Liverpool dished out to Bournemouth in August of this season, and his Liverpool team have also hit seven in a game five times (Maribor, Spartak Moscow, Crystal Palace, Lincoln City and Rangers), while his biggest win as a boss in Germany was Dortmund's 6-0 crushing of Arminia Bielefeld in May 2009.

Klopp has suffered four defeats by five-goal margins, the worst he has had to endure, with Aston Villa inflicting two of those: 7-2 in October 2020 and 5-0 in December 2019 – albeit the latter with Klopp and his frontline Liverpool stars out of the country on Club World Cup duty. There was also a 6-1 torching for Mainz at the hands of Werder Bremen in October 2006, and Liverpool's 5-0 whipping by Guardiola's City.

When it comes to promoting young talent, Klopp has rarely hesitated. His youngest player was Harvey Elliott, now a first-team squad regular at Liverpool, who faced MK Dons in the EFL Cup at the age of 16 years and 174 days in September 2019.

Klopp has fielded five 16-year-olds for Liverpool, plus seven 17-year-olds, while he also gave chances to the 17-year-old Mario Gotze at Dortmund, and Mario Vrancic, also 17, during his time at Mainz. Gotze went on to become a World Cup final match-winner.

His oldest player was Peter Neustadter, a Kazakh defender who was older than Klopp himself, aged 37 years and 176 days, when he turned out for Mainz against Alemannia Aachen in the Bundesliga's second tier in August 2003.

Warhorse midfielder James Milner could yet break that record as the oldest Liverpool player to have appeared for Klopp, aged 37 years and 13 days when he played in the recent FA Cup replay win against Wolves this week.

James Woodburn remains the youngest scorer for Klopp after hitting the net against Leeds in an EFL Cup clash in November 2016 at the age of 17 years and 45 days, while Sebastian Kehl ranks as his oldest scorer – 35 years and 53 days old when he bagged for Dortmund against Hoffenheim in a DFB-Pokal quarter-final in April 2015.

Klopp's kingpins

Roberto Firmino has played more games for Klopp than anyone, racking up 341 outings for Liverpool under the manager, with Milner (301) next on the list.

When it comes to starters, though, we get a different picture, with former Dortmund goalkeeper Roman Weidenfeller top of the list with 280 games, followed by another BVB stalwart, Neven Subotic (278), and then Firmino (277 starts). Milner is a long way down that list, with 112 of the veteran's appearances for Klopp having come as a substitute.

Mohamed Salah has made 282 appearances and 261 starts for Klopp, and when it comes to scorers for the Reds manager, the brilliant Egyptian is the untouchable number one.

His 173 goals put him streets ahead of Klopp's next highest scorer, Sadio Mane (120), with Firmino (107) and former Dortmund supreme finisher Robert Lewandowski (103) being the only other players to reach three figures.

Among players with 10 or more goals for Klopp teams, Salah has also scored at the fastest rate, netting once every 133 minutes, with Lewandowski in a tie for second place with Darwin Nunez, both scoring at one per 139 minutes. Nunez scrapes onto the list, having scored 10 times so far.

Lewandowski hit four hat-tricks for Klopp's Dortmund, while Salah has managed five for Liverpool under the German.

Both men once hit four in a game for Klopp, with Lewandowski doing so in a Champions League semi-final against Real Madrid, and Salah in a Premier League match against Watford.

The manager teased plenty out of those two down the years, and Klopp will doubtless look to Salah, a former Chelsea player, to ensure his 1,000th game brings cause for celebration.

Julian Nagelsmann is finding his Bayern Munich side "fun to watch" after they hammered Mainz 6-2 to go top of the Bundesliga on Saturday.

The ruthless Bavarian giants extended their winning streak to six matches by putting Mainz to the sword at the Allianz Arena following a 3-0 midweek victory at Barcelona in the Champions League.

Bayern had six different goalscorers for only the third time in a Bundesliga match, with Mainz the opponents in two of those games, the other occasion being in August 2019.

Serge Gnabry, Jamal Musiala and Sadio Mane were on target in a first half that ended with Silvan Widmer pulling a goal back just after Sven Ulreich saved a Jonathan Burkardt penalty.

Leon Goretzka, Mathys Tel and the in-form Eric Maxim Choupo-Moting were on target in the second half, with Marcus Ingvartsen scoring Mainz's second goal after a mistake from Ulrich.

That is now a staggering 39 goals Bayern have scored in a nine-match unbeaten run, moving them above Union Berlin at the summit, and head coach Nagelsmann is lapping up the entertainment.

He said: "I think we had difficult five to 10 minutes at the beginning of the first and second half. Otherwise we did really well.

"Big compliment to the team for performing this way every three days. It's fun to watch – a mix of quality and attitude. Compliments to my players."

Mane and Musiala caused Mainz all sort of problems as Bayern came forward with wave after wave of attacks.

Nagelsmann praised big-money signing Mane, who has already scored 11 goals in his first season for the club.

He said: "I'm happy with Sadio Mane's performance. The development of the past two weeks was good because of his position.

"He plays more on the wing where he played at Liverpool. He did well today, like he did in Barcelona and hopefully will continue this way."

Jamal Musiala scored his 10th goal of the season as ruthless Bayern Munich thrashed Mainz 6-2 in a pulsating Bundesliga contest to go top of the table.

It had been 57 days since Julian Nagelsmann's side were last at the summit, but they moved above Union Berlin with a sixth consecutive win on Saturday.

First-half goals from Serge Gnabry, the hugely impressive Musiala and Sadio Mane put them in command at the Allianz Arena, the Senegal forward finishing from the rebound after Robin Zentner saved his penalty.

Silvan Widmer pulled one back on the stroke of half-time just after Sven Ulreich kept out a Jonathan Burkardt spot-kick, but goals from Leon Goretzka and Mathys Tel put Bayern out of sight.

Marcus Ingvartsen capitalised on a terrible mistake from Ulreich to score Mainz's second goal, before the in-form Eric Maxim Choupo-Moting had the final stay with a late goal against his former club.

The champions took the lead in the fifth minute, Mane cutting the ball back and Gnabry finishing with his left foot from close range after a clever dummy from Musiala.

Musiala doubled their lead just before the half-hour mark, finishing off another slick move a clinical-right foot finish after exchanging passes with Choupo-Moting.

Burkardt rattled the crossbar and Jae-Sung Lee struck the post following up before Mane added a third Bayern goal, following up to tuck home after Zentner palmed his tame spot-kick back into his path.

Referee Felix Zwayer awarded that penalty following a VAR check for Alexander Hack's tackle on Mane and he pointed to the spot again after another check on the pitchside monitor, deeming that Ulreich had caught Anthony Caci when attempting to deal with a corner

Ulreich tipped Burkardt's spot-kick over the crossbar, but there was more drama when Widmer nodded in the resulting corner just before the break.

Benjamin Pavard replaced the injured Matthijs de Ligt for a second half that Mainz started brightly, but Choupo-Moting almost restored Bayern's three-goal lead when he hit an upright.

Goretzka duly got on the end of Mane's cross to nod in the Bavarian giants' fourth 58 after minutes and Tel came off the bench to got in on the act with a deflected strike 11 minutes from time.

Ulreich's awful pass gifted Ingvartsen the chance to slot home in the closing stages and there was still time for Choupo-Moting to round off the scoring with his right foot after Kingsley Coman picked him out.

Manuel Neuer and Thomas Muller – pillars of the Germany national team over the last decade – are battling to prove their fitness with barely three weeks remaining until the World Cup begins.

Bayern Munich boss Julian Nagelsmann confirmed in a press conference on Friday that neither player will be fit enough to feature in Saturday's Bundesliga game against Mainz.

Goalkeeper Neuer remains troubled by a shoulder issue, while attacking midfielder Muller has a hip problem, and Nagelsmann could not say with conviction when both will be back in club action.

The news will inevitably be a worry for Germany boss Hansi Flick, as the former Bayern head coach finalises his plans for the Qatar 2022 finals.

Muller played for half an hour as a substitute in Bayern's 3-0 win at Barcelona on Wednesday, but the 33-year-old will not be risked at all against Mainz, and almost certainly will also sit out the Champions League meeting with Inter next Tuesday.

"He has irritation in his hip again, in the pelvic area," Nagelsmann said. "He won't be able to play, probably not even on Tuesday. We'll probably have to take him out for a week to give him a break.

"Thomas is in good spirits. We talked to a couple of medical professionals yesterday and tried to get a better picture of everything, but the picture didn't really change.

"It's not something that goes away with pain medication either. It feels blocked, and it's difficult to define how the pain is manifesting itself. I decided it would be better just to take him out of action for the time being.

"[Saturday] is the type of game where even for 10 or 15 minutes you have to give absolutely everything, so if we give him that 10 or 15 minutes, he's ultimately going to have to drop out potentially for the next game. We've got to see how it develops and how it reacts.

"The key right now is instead of blindly testing it out constantly, to give it a bit of calm and see how it reacts to that and then see how his recovery goes."

Neuer, the 36-year-old captain of Bayern and Germany, has played no active part since Bayern's 2-2 draw at Borussia Dortmund on October 8.

It is obvious to Nagelsmann that having Neuer fit is not only a priority for Bayern but a matter of national interest.

There are no promises at the moment, but Nagelsmann is hoping Neuer may be able to return next weekend at Hertha Berlin.

"I'm not a mystic that can see into the future," Nagelsmann said. "We put him in the game against Dortmund and maybe that was a game too early, and now he's sat out a couple of games.

"It's very difficult for me to know how the pain will be managed. It's a structural area of the body that needs time to heal and a joint that needs a bit of calm as well, so if you're constantly testing it and putting a burden on it, it can be tough.

"I'm anticipating he will be ready for the World Cup, but I'm not a psychic. We're going to do everything we can to help him be there for the World Cup."

Bayern are the hosts on Saturday against a Mainz team who led at the Allianz Arena last season before slipping to a 2-1 defeat.

However, Mainz have beaten Bayern twice in the past two seasons, both times when having home advantage.

Among sides currently in the top flight, only Augsburg have also taken six points from their last three matches against Bayern – no teams have managed more.

Heading into this meeting, Bayern and Mainz have both won their last two games, each scoring seven goals and conceding none – a league high in this timeframe.

Mainz are also top of the away form table this season with 12 points from six away games, marking them down as a threat.

Bayern nevertheless head into the weekend programme just one point behind early leaders Union Berlin, who must wait until Sunday before tackling Borussia Monchengladbach.

"We're in a good rhythm right now," said Nagelsmann. "Against Barcelona, we looked like a solid unit who all had the same goal in mind. The team have a great connection with one another."

Bayern Munich have been drawn against Mainz in the last 16 of the DFB-Pokal, while Borussia Dortmund face a derby showdown with Bochum.

Record 20-time winners Bayern saw off Viktoria Koln and Augsburg to reach the third round for the first time in three seasons.

Julian Nagelsmann's side now face a tricky trip to Mainz, who are sixth in the Bundesliga and have defeated Bayern in their past two meetings on home soil.

Dortmund have also been drawn against top-flight opposition, with a trip to local rivals Bochum awaiting them when the ties are played at the end of January.

Defending champions RB Leipzig will host Hoffenheim, meanwhile, and surprise Bundesliga leaders Union Berlin are at home to Wolfsburg.

Elsewhere, Sandhausen have been drawn against Freiburg, Stuttgart face a trip to Paderborn, Eintracht Frankfurt host Darmstadt and Nurnberg will meet Fortuna Dusseldorf.

Mainz will push ahead with plans to face Newcastle United in a pre-season friendly despite backlash from their supporters.

Newcastle will face German clubs Mainz and 1860 Munich in Austria ahead of the 2022-23 season.

But the scheduled matches have not been welcomed by supporters of those clubs due to the identity of Newcastle's owners.

The consortium that bought Newcastle last October includes Saudi Arabia's Public Investment Fund (PIF), which owns 80 per cent of the club.

Saudi Arabia's human rights record is of major concern, along with its role in the war in Yemen.

But Mainz insist they cannot afford to cancel the Newcastle friendly, both because of the need to prepare for the Bundesliga season and due to contractual obligations.

"A friendly against a big English club is first of all a really good test for us," said chairman Stefan Hofmann in a statement in which Mainz confirmed they had held further talks with Newcastle and would plan to meet with fans. "It's also important for our team’s pre-season preparations.

"After weighing up our options and not having an appropriate alternative opponent of this standard available, we agreed to play this game.

"We didn't expect the reaction we got from some fans. We respect them and regret that these concerns have arisen because it's our responsibility to start the new season as one big unit together with our fans."

Mainz board member Christian Heidel added: "From a footballing perspective, we can't afford to miss out on this friendly.

"A one-sided cancellation of the fixture, as has been demanded by some fans, is not feasible, because were we to not honour our contractual obligations, this could have serious legal and economic consequences for us, and so we're going to stand by the contractual agreement."

Mainz coach Bo Svensson had already addressed the concerns, saying as reported by Bild: "On the one hand, I can understand the arguments.

"[But] whenever it comes to football, things get very inflated and become huge issues."

Referring to the PIF's shares in Disney, Svensson added: "How far are we going? Will we then also forego Disney films with our children?"

1860 coach Michael Kollner said to db24: "You always have to be a bit careful when conducting a moral discussion. I find that difficult. You can find something in everyone.

"We haven't done everything right in the past either – and teams are still playing against us in preparation.

"Newcastle was bought by someone with the money he has. I don't know if we are always entitled to evaluate things – especially in times when we have completely different issues in Europe.

"Unity looks different. I'm responsible for the sport – and I'm glad we got this test match."

Julian Nagelsmann bemoaned Bayern Munich's underwhelming performance and suggested change is needed after the Bundesliga champions succumbed to defeat at Mainz.

Bayern secured a record 10th straight league title with Klassiker victory over Borussia Dortmund last weekend but were caught cold by Mainz after first-half strikes from Jonathan Burkardt and Moussa Niakhate.

Robert Lewandowski reduced the deficit with his 18th away league goal this season, setting a Bundesliga record for a single campaign, while taking his tally to 49 in all competitions – the most of any player in Europe's top five leagues.

Leandro Barreiro Martins restored the two-goal cushion after the interval for Bo Svensson's hosts as Mainz coasted to just a second league win over an uncharacteristically poor Bayern in their last 10 attempts.

Nagelsmann expressed frustration with his side after the defeat but acknowledged a downturn in performance was to be expected after the title win.

"We had too many performances and defeats of this kind this season," he told reporters.

"I have an explanation for it, but I won't give it to you. It's not for the media. I say it internally.

"After winning the 10th title in a row, it's a bit human but we still have to play for the badge on our chest.

"It seems like the passion isn't really there anymore. We reached a point where something needs to change. That's where we are right now."

Bundesliga champions Bayern Munich fell to a 3-1 defeat at Mainz despite Robert Lewandowski setting another record.

Julian Nagelsmann's side sealed a record 10th straight league title by defeating Borussia Dortmund last time out, but were soon behind on Saturday after strikes from Jonathan Burkardt and Moussa Niakhate.

Robert Lewandowski halved the arrears with his 18th away league goal this season – a new Bundesliga benchmark for a single campaign – before Leandro Barreiro Martins restored Mainz's two-goal cushion after the interval.

Bayern were unable to respond as the champions suffered just a second defeat in their last 10 games against Mainz, who moved up to ninth with victory.

Burkardt cannoned against the crossbar and the post, while the unmarked Alexander Hack was denied by the woodwork but Mainz's early dominance soon paid dividends.

Sven Ulreich thwarted Karim Onisiwo from close range yet could not stop Burkardt when the striker powered a left-footed attempt home following Dominik Kohr's headed offload.

Niakhate doubled Mainz's advantage when he tapped in after Anton Stach's flick, before Lewandowski rolled into the bottom-right corner following Eric Maxim Choupo-Moting's pass to reduce the deficit.

Barreiro Martins almost restored the hosts' two-goal lead before the interval, only for his left-footed free-kick to curl narrowly wide.

But Barreiro Martins' luck was in after the break when his strike deflected in off Benjamin Pavard.

Burkardt dragged wide and Onisiwo smashed onto the crossbar from the edge of the area as Bayern, who repeatedly appeared frail on the counter-attack, were unable to mount a comeback.

What does it mean? Bayern caught cold on the road at Mainz again

Bayern had won eight of their last nine league meetings with Mainz, though the one blemish on their record came in this fixture last season when the hosts ran out 2-1 winners.

Mainz scored first on that occasion and followed suit in this game as they opened the scoring for four straight games against the Bavarian giants – no other current Bundesliga side have achieved this consecutively more than twice.

Super Stach shines

Stach was a constant presence in the middle of the park for Bo Svensson's team, setting up Niakhate's goal – one of a game-leading seven key passes the midfielder supplied for Mainz.

Legendary Lewandowski

Despite speculation of a move away from Bayern with just over a year left on his contract, Lewandowski continues to deliver. His tally in all competitions this season now stands at 49.

No player has managed more goals in Europe's top five leagues, while the Poland international also put his name to yet another Bundesliga record.

What's next?

Bayern host Stuttgart on May 8, while Mainz make the trip to Hertha Berlin the day before.

Bayern Munich head coach Julian Nagelsmann reiterated his desire for Robert Lewandowski to stay at the club amid ongoing speculation over his future.

Lewandowski has scored 33 goals in the Bundesliga this season, 12 more than nearest rival Patrick Schick, to fire Bayern to a record-setting 10th straight league title with three games to spare.

The Poland international has found the net once every 81 minutes in the top flight this campaign, while no player has managed more than his 48 goals across all competitions in Europe's top five leagues.

However, questions persist as to the future of Lewandowski, who is entering the final year of his contract at the Allianz Arena with Barcelona reportedly preparing to swoop for the 33-year-old.

Bayern sporting director Hasan Salihamidzic insists the talisman will not be sold to avoid losing him on a free transfer, but Lewandowski suggested no new contract talks have been opened by the club.

Nagelsmann, speaking ahead of Saturday's visit to Mainz, reaffirmed his stance on wanting to keep his star striker at Bayern for as long as possible.

"It's always good when you have planning security in all areas of life. I've said it at least 50 times that of course I wish he would stay, nothing has changed this week. That's my point of view," he told reporters.

Salihamidzic has already rebuffed talk of signing Borussia Dortmund's Erling Haaland, who will reportedly be available for a €75million release clause at the end of the season, as a replacement for Lewandowski.

Nagelsmann echoed Salihamidzic's sentiment as he ruled out moving for Haaland, who has scored 82 goals and supplied 19 assists in 86 appearances in all competitions since his Dortmund debut in January 2020.

Pressed on comparisons between the two strikers, the Bayern coach responded: "These are two different types of players that you can't compare. It's like apples and oranges."

Lewandowski is likely to feature at Mainz, fitness permitting, but Nagelsmann confirmed he will be without Thomas Muller, who has 17 top-flight assists this term – the most of any player in Europe's top five leagues.

"Muller is ill and will not travel this weekend. We will try to give some players the opportunity to start," he continued.

"[Eric Maxim] Choupo-Moting will definitely be in the starting line-up, that much I can say for sure. 

"The virtue of a winning mentality is noticeable in the lads even after the championship in training. My everyday life is a little more relaxed than in the middle of the season."

Bayern would surpass the Bundesliga record for most away goals in a season (47, a record set by Bayern in the 2019-20 season) with two strikes at Mainz, but Nagelsmann appeared uninterested by that feat.

"You always have to be a bit careful when it comes to respect for the opponent," he added on the possible record. 

"Of course we always want to score a lot of goals, that's what makes football so appealing. It won't be easy, but we're trying hard to find goals and play a good game offensively."

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."

Mainz were hit with an €8,000 beer bill on Tuesday after their fans showered Union Berlin forward Max Kruse during a recent Bundesliga game.

Former Germany international Kruse was targeted after he was substituted in the 83rd minute of Union's 2-1 win at Mainz in early October.

He had beer cups thrown over him as he walked behind the goal on his way off the pitch, resulting in a soaking for the 33-year-old.

Kruse kept his cool and said in a post-match interview with DAZN: "Why should something like that provoke me? What should I say to such nonsense heads?"

Mainz were charged over the behaviour of their fans and German Football Association (DFB) chiefs have now passed judgement.

"The sports court of the DFB fined the Bundesliga club Mainz 8,000 euros in single judge proceedings after the DFB control committee brought charges for unsportsmanlike conduct on the part of its supporters," the DFB said in a statement.

"In the 83rd minute of the Bundesliga game against Union Berlin on October 3, 2021, the Berlin player Max Kruse was showered with beer by spectators from Mainz after his substitution. The association has agreed to the ruling, the ruling is now final."

Hansi Flick admitted his Bayern Munich team were tired and ripe to be punished after a 2-1 defeat at Mainz delayed title celebrations.

Chasing the win that would have clinched a ninth successive Bundesliga title, Bayern gave a lethargic display and a last-gasp goal from Robert Lewandowski was as much as they deserved.

Mainz seized advantage as the one-time strugglers took their points tally to 28 from 16 games under new head coach Bo Svensson, soaring five points clear of the relegation zone.

Bayern boss Flick said: "We all know that just as the team has often shown its quality, something like that can happen. It's a shame we couldn't take the step today.

"But you have to understand that the team is tired. We were too harmless.

"We want to win every game, that was also the case today. We didn't perform well, you have to accept that.

"The team have many minutes in their legs. We just weren't strong enough."

First-half goals from Jonathan Burkardt and Robin Quaison put Bayern in a tangle, and the stoppage-time reply from Lewandowski, returning from injury, came too late to spark anything more.

Lewandowski now has 36 goals for the season, meaning he trails Gerd Muller's Bundesliga record by four with three rounds of games remaining.

His goal in Saturday's game was a gift rather than the result of any great personal endeavour, with a poor defensive header leaving Lewandowski the task of stroking the ball past cruelly exposed goalkeeper Robin Zentner.

Bayern slipped to a first Bundesliga defeat at Mainz since 2011, having won all eight of their away games against the 05ers since that 3-2 loss a decade ago.

Manuel Neuer was unusually at fault for the third-minute opening goal, getting in the way of the powerful shot from Burkardt but only being able to divert it into the corner of his net.

"I wasn't blinded by the sun," said Neuer, according to TZ.

"The ball was close to [David] Alaba, I couldn't see it well. I tried to put my arm up, I was unlucky."

Bayern have been hit by a Champions League quarter-final exit, the announcement from Flick that he wants to be released from his contract at the end of the season, and criticism from fans aimed at Hasan Salihamidzic.

That may have been a contributing factor to Saturday's below-par effort, but Neuer pointed to Mainz's qualities.

"We weren't surprised," said the goalkeeper. "It was clear that they went into the game with a high level of motivation. Our body language was bad."

Bayern could still be crowned champions this weekend, but RB Leipzig would need to lose to Stuttgart on Sunday.

"I would have preferred to have got it done ourselves," said Neuer. "The defeat hits us hard after the last few weeks."
