Bayern Munich put pressure back on Borussia Dortmund as they battled to a 1-0 victory at Eintracht Frankfurt on Saturday.

The leaders were kept at bay by Oliver Glasner's side until Leroy Sane struck with 19 minutes of normal time remaining.

The victory, a first against Glasner for Bayern boss Julian Nagelsmann in his Bundesliga coaching career at the sixth attempt, moved the champions nine points clear of Dortmund at the top of the table ahead of their clash with Augsburg on Sunday.

Frankfurt largely contained Bayern in a cagey first half, although Kevin Trapp had to make a strong double save to keep out Joshua Kimmich's volley and Kingsley Coman's follow-up.

Robert Lewandowski was denied following a good throughball from Serge Gnabry and Trapp sprung to keep out another effort from the striker two minutes later.

Just at it looked like Bayern were running out of ideas, Kimmich slid the ball through to Sane in the box, and the winger kept his composure to slot past Trapp.

Frankfurt mounted some late pressure, leading to a few scrambles in the Bayern box, but Sven Ulreich was mostly untroubled in goal.

Eric Maxim Choupo-Moting ignored a free Sane, shooting straight at Trapp when a cross seemed the better option, but Frankfurt could not punish the error.

One topic sure to take up plenty of column inches at the end of the season will be the appointment of Manchester United's next permanent manager, but one front-runner may be out of the race already.

Paris Saint-Germain boss Mauricio Pochettino has been heavily tipped to make a sensational return to the Premier League to take over at Old Trafford.

However, the former Tottenham manager may have already turned down the opportunity while he waits for what he considers to be a better offer from elsewhere.

TOP STORY - POCHETTINO HOLDING OUT FOR REAL MADRID

Pochettino has been linked with the manager's role at Man Utd since Ole Gunnar Solskjaer was sacked in November, but has turned the opportunity down as he waits for Real Madrid, according to Sport.

Ralf Rangnick was appointed as interim manager at the Premier League club after Solskjaer's departure and will play a role in deciding on the next permanent Red Devils boss at the end of the campaign.

However, it seems the Argentine may have ruled himself out of contention as he believes he could have an opportunity waiting for him at the Santiago Bernabeu.

The report claims that Los Blancos president Florentino Perez has Pochettino "in mind as one of Madrid's future coaches", and that should the Spanish giants decide to dismiss Carlo Ancelotti at the end of the season, he would be one of the leading candidates to replace the Italian at the helm.

ROUND-UP

- PSG are considering an off-season move for Chelsea star N'Golo Kante, whose contract at the Blues expires in 2023, according to the Telegraph.

- The Daily Express reports that Harry Kane may once again try to force a move away from Tottenham if manager Antonio Conte does leave the club.

- Georginio Wijnaldum could leave PSG after only one season, with West Ham, Atletico Madrid and Aston Villa among those interested in the former Liverpool midfielder, says Calciomercato.

- The same publication also believes that RB Leipzig left-back Angelino could leave Germany at the end of the season, with Barcelona, Arsenal and Tottenham all interested in the former Manchester City man.

- Chelsea defender Andreas Christensen will not join another Premier League club when his contract expires at the end of the season, but could move to either Barcelona or Bayern Munich, according to Fabrizio Romano.

- Romano also reports that PSG are "really convinced" to make the loan move of left-back Nuno Mendes from Sporting CP permanent for a fee of around €40million.

Julian Nagelsmann has been left shocked by Russia's invasion of Ukraine, with the Bayern Munich boss admitting he was fearful of the consequences.

Russia, to widespread condemnation, invaded neighbouring Ukraine on Thursday. That conflict escalated on Friday, with fighting having reached the capital of Kyiv, which is Munich's twin city.

Bayern confirmed that their Allianz Arena stadium would be lit up in the yellow and blue of the Ukrainian flag on Friday evening, to show solidarity with Ukraine.

Bayern played against Dynamo Kyiv in the group stages of this season's Champions League, and Nagelsmann expressed his shock at seeing a city where he and his team visited now being in the middle of a war zone.

"How difficult is it to think about everyday life? Obviously it's difficult, I'm shocked," he told a news conference.

"I'm also to a certain extent fearful that this is happening in a country where only recently we jogged across the pitch, looked at the beautiful city [Kyiv] and now you see these terrible pictures from Ukraine.

"It's not easy to talk about football. Of course you think about your concerns with continuing to do your job well but if you look at the news it makes you think a lot about what's going on and what the consequences will be.

"First of all for the people in Ukraine, it's dramatic, it's shocking. Yesterday I read a very good phrase that said 'there's no way to peace, peace is the way'. I think that should be the motto again as quickly as possible."

Russian politicians, certain high-profile individuals and companies have been hit by sanctions from many countries in response to the invasion.

In sport, the International Olympic Committee (IOC) has urged federations planning to host events in Russia and Belarus, who have supported the invasion, to be relocated or cancelled.

Manchester United have ended their sponsorship deal with Russian airline Aeroflot, Formula One has removed the Russian Grand Prix from its calendar and UEFA has moved this season's Champions League final from St Petersburg to Paris.

Nagelsmann fully backed UEFA's decision.

"Firstly it's good that UEFA decided quickly and decided the right way," he said. "It's always good to have a quick decision and a good sign."

Bundesliga leaders Bayern face Eintracht Frankfurt on Saturday.

Bayern Munich have announced that Thomas Muller has tested positive for COVID-19.

The veteran forward contracted the virus for the first time in February 2021 following the Club World Cup in Doha.

Muller has now returned a positive coronavirus test for a second occasion, with the reigning Bundesliga champions confirming he will serve another period of self-isolation.

That likely rules him out of the clash with Eintracht Frankfurt on Saturday as Julian Nagelsmann's side look to extend their six-point advantage at the summit of the German top flight.

Muller may target a return for the meeting with Bayer Leverkusen on March 5, dependent on when he returns a negative test and comes back into training.

The Germany international's absence will serve as a blow for the Bavarian team, given he leads the assist charts this season across all competitions at Bayern (19).

Muller has 10 goals to his name - only Robert Lewandowski (39), Leroy Sane and Serge Gnabry (both 12) have managed more - and has created a team-leading 89 chances, 20 more than any team-mate.

The 32-year-old has played the most games for his side this term as well (33), and his absence will frustrate Nagelsmann, who is still without Manuel Neuer after he required knee surgery.

The goalkeeper did, however, return to light training on Monday so could provide a boost for Bayern in the near future, with Alexander Nubel currently deputising in goal.

Manuel Neuer's eventual exit from Bayern Munich will be a "bigger problem" than Robert Lewandowski departing, according to former boss Felix Magath.

Neuer joined the Bavarian side from Schalke in 2011 and holds the record for the most clean sheets in the Bundesliga (209), having surpassed Oliver Kahn (196) in 2021.

The Germany international's contract is due to expire at the end of the next season, when he will be 37, leading to speculation over his future at Julian Nagelsmann's team.

The goalkeeper has been absent in recent weeks after undergoing knee surgery, coinciding with a downturn in Bayern form.

Nagelsmann's side were downed 4-2 by Bochum in their first game without their captain and were then held by Salzburg before ending a poor run of form with a 4-1 win over Greuther Furth last time out.

Neuer returned to light training on Monday and Magath, who completed consecutive doubles in charge of Bayern between in the 2004-05 and 2005-06 seasons, believes the 35-year-old is more important to the reigning Bundesliga champions than talisman Lewandowski.

"Bayern and the national team live strongly from Manuel Neuer," Magath said to German outlet Kicker, adding: "Marc-Andre ter Stegen can be very good, but he doesn't have Neuer's charisma. Manuel is a stroke of luck for German football."

When pushed for a comparison between Neuer and Lewandowski, Magath responded: "It will be a bigger problem for Bayern when Neuer is gone."

Neuer helped Bayern earn a 3-2 home win over RB Leipzig in his last outing, as he matched Oliver Kahn's all-time record of 310 Bundesliga wins by a player. He achieved the first 77 wins with Schalke.

Meanwhile, Lewandowski has again been in scintillating form this campaign, scoring 39 times across all competitions – 14 more than any other player across Europe's top-five leagues.

The Poland forward currently finds the net once every 71.2 minutes on average, with only Borussia Dortmund's Erling Haaland managing goals at a faster rate among those to have scored 15 or more in the same group.

While Neuer's return date remains unconfirmed, Lewandowski will hope to continue his prolific term as Bayern look to extend their six-point advantage at the Bundesliga summit when they face Eintracht Frankfurt on Saturday.

Julian Nagelsmann called for improvements from Bayern Munich and insisted his side must not become disenchanted after two disappointing performances.

The reigning Bundesliga champions are six points clear of second-placed Borussia Dortmund at the summit, despite falling to a 4-2 loss at Bochum last Saturday.

Nagelsmann's side followed up that disappointing defeat with another unspectacular performance in Salzburg on Wednesday, where they required a late Kingsley Coman strike to secure a 1-1 draw in the first leg of their Champions League last-16 clash.

The former RB Leipzig head coach expressed his frustrations with the recent outings but expects his team to bounce back when they travel to Furth on Sunday.

"We want to remain critical and have a certain claim in terms of success," Nagelsmann told reporters at Friday's pre-match news conference.

"We have to back that up, but we mustn't tear ourselves apart either. The tide can turn quickly, there is a lot of evaluation.

"The mood is appropriate for the fact that we have not won twice. Tomorrow's winner learns from today's defeat.

"We had detailed discussions after the game against Bochum. We didn't score an early goal in the second half, it was similar in Salzburg. But the will was obvious there. I was totally satisfied, I'm convinced that as a Bayern player you have the right to be successful.

"And that should also arouse greed. We saw that we lost clearly against a team that isn't aspiring to the Champions League. That should be warning enough. No one walks around with the handbrake on purpose."

The Bochum loss was Bayern's first to a newly promoted side in 16 games, but the Bavarians may take confidence from the fact they have not lost two consecutive Bundesliga games against promoted teams since 1997. Furth joined Bochum in climbing out of the second tier last season.

However, Bayern have experienced their worst start to the second half of a top-flight season in 10 years, with only nine points accrued from their first five games of 2022, winning three games and losing twice.

The last time they lost two or more matches in the first five matchdays of the second half of the season was in 2008-09 under Jurgen Klinsmann (three), and Nagelsmann's task could be made more difficult as he revealed doubts over the fitness of Coman and Serge Gnabry.

Nevertheless, Nagelsmann remained balanced in his views as he prepares Bayern for just their sixth meeting in professional football with Furth.

"Football is a head game," he added. "We didn't intentionally play a bad first half in Bochum. You can't shake off the cup game that easily either.

"There's often a black-and-white mindset. We have three points more than last year. We need a little more self-image and sovereignty. The head is an important part of the body.

"It's often the case that you have more to do psychologically than in terms of football. I train a world-class team here.

"You have to recognise the moment when a structure doesn't fit perfectly. In the last three games we haven't been completely in the flow. In the end it's about delivering and not about taking long-term steps."

Cristiano Ronaldo ended a run of six matches without scoring in Tuesday's win over Brighton and Hove Albion, but the Manchester United forward's future remains uncertain.

The five-time Ballon d'Or winner's second spell at Old Trafford has not gone quite to plan and a number of European clubs are said to be circling should he depart.

If reports are accurate, it may well be that a reunion with former boss Jose Mourinho is on the cards for Ronaldo in the coming months.

TOP STORY – ROMA IN FOR RONALDO

Roma are one of three clubs currently in the running to sign Ronaldo should he depart United in the next transfer window, according to The Sun.

Giallorossi boss Mourinho previously managed Ronaldo at Real Madrid and is eager to bolster his squad with a superstar signing.

However, it is not known if the 37-year-old would welcome a return to Serie A, where he previously spent three seasons playing for Juventus ahead of rejoining United.

European heavyweights Bayern Munich and Paris Saint-Germain are reported to be the other two sides to have expressed an interest in Ronaldo.

ROUND-UP

- Fabrizio Romano claims Chelsea are now solely focused on signing Jules Kounde from Sevilla after being told that top defensive target Marquinhos will not be sold by PSG.

- According to The Sun, Armando Broja's form on loan with Southampton has seen the Chelsea youngster's name added to Bayern and Borussia Dortmund's list of targets.

- Manchester City have bid £5.5million (€6.5m) for Atletico Mineiro's teenage winger Savio, suggests The Guardian, with the intention of then loaning him out to PSV.

- Juan Mata will depart United as a free agent at the end of the campaign, claims Nicolo Schira. The midfielder may look to see out his career in his Spanish homeland.

- Ralf Rangnick is eager for United to bring in Christopher Nkunku from RB Leipzig, according to ESPN. Madrid, Liverpool, Man City and Arsenal have also been linked.

It's November 25, 2020. A young German winger stands on the touchline anxiously waiting to step on to the Allianz Arena pitch for his Champions League debut in his hometown.

But as he waits to be allowed on, there are people watching both on television and in the largely empty stands who know this isn't how it should've been.

Rather than wearing the all-red of Bayern Munich, Karim Adeyemi jogs on in the all-black of Salzburg with the Austrian champions 3-0 down.

A technically gifted and rapid forward, Adeyemi has long been considered one of Germany's most promising young players, having cost Salzburg a reported €3million when he was 16.

Adeyemi had left Bayern six years earlier. It's a detail that has dominated much of his early professional career, with questions about why he left never far away.

Now 20, Adeyemi has previously spoken at length about his attitude as a kid, how learning wasn't much to his liking and distraction was a regular nuisance to him. These factors certainly didn't help at Bayern.

Neither, Adeyemi alleged in the past, did the club, who he said showed little support to players who strayed from "the plan". The collective, rather than individualistic talents, was prioritised.

He and Bayern were simply not a good match at the time. He left Die Roten and, while such a disappointment might've been enough to derail other ordinary kids, Adeyemi has since proven he is rather extraordinary.

A move to a smaller local club, Unterhaching, soon followed. It was there that, according to youth coach Marc Unterberger, Adeyemi was able to develop with a greater degree of individual emphasis and that eventually translated into him becoming a better asset for the team as a whole.

"He had his own thoughts on how to deal with things," Unterberger told Stats Perform in 2021. "We never wanted to change him completely, and I think we succeeded quite well. Karim is a really great guy and a great person.

"Until the time Karim came to us, we had never had such an exceptional player in our youth division.

"Of course, as a young person, you benefit from being accepted for who you are, but I would like to make it very clear that there was no situation within the team in which Karim behaved in such a way that we as a club were forced to act.

"On the contrary, over time he developed more and more towards putting himself at the service of the team. He was easily distracted, that's right, but let's be honest, something like this is normal when young people develop."

Unterberger arguably knows Adeyemi better than any other coach, given he was there for the youngster's entire six-year stay at Unterhaching.

"I can still remember it very well, the first time I saw him play in an Under-11 tournament," he recalled.

"Back then he was still playing for TSV Forstenried. My first thought was: 'We absolutely need this player'. Fortunately, it worked out later!"

That might be something of an understatement in reality. The €3m fee that Unterhaching received made him the most expensive Under-18 German player ever at the time, while 2019 saw him win the Fritz-Walter Gold Medal, an award handed out to Germany's best youth player. Previous winners include Timo Werner, Emre Can and Mario Gotze.

But most importantly, that move proved an unequivocal success for the player, as did his next.

Adeyemi confirmed to Stats Perform last year that he rejected the chance to join Chelsea from Unterhaching in his teens, instead opting to move just over the border to Salzburg. Had he gone to London, maybe he would've broken into their first-team – but it's probably just as likely that he'd have been lost among the Blues' army of loan players.

That's not to say loans can't work. Adeyemi's Salzburg career was carefully mapped out for him even before he joined, and that included an initial 18-month stint with Liefering, who essentially act as a B team. A haul of 15 goals and eight assists in the second tier provided strong evidence the teenager was ready for the step up in 2020.

His introduction to top-tier football wasn't quite so explosive, only having a hand in goals in six of his first 29 Austrian Bundesliga matches, but a key factor here was the need to remain patient – only nine of those 29 games were as a starter.

It wasn't until the final three months of 2020-21 that Adeyemi began to nail down a starting role, with seven of his 11 starts coming between mid-February and the end of May. This period also yielded six of his seven league goals.

This proved the final push he needed – with Patson Daka leaving for Leicester City, Adeyemi went from being the forwards' supporting act to the leading man in attack.

As you'd expect, this led to a bit of a change in his role, but there's no doubt he's thriving, securing his first senior international cap in September and finding himself linked heavily with Borussia Dortmund.

Sure, chance creation frequency is down (2.7 per 90, to 1.6), but the pay-off in terms of his effectiveness in front of goal is more than worth it.

His 14 goals is a league high, while only Kelvin Yeboah (11.2) – who has since joined Genoa – can better Adeyemi's 10.1 non-penalty expected goals (np-xG). Though on a per-90-minute basis, Adeyemi ranks first in the division with 0.72 np-xG (minimum 650 minutes played).

But it would be doing Adeyemi a huge disservice to give the impression he's 'just' some poacher. He's an immensely exciting player characterised by his explosive pace, low centre of gravity and silky ability on the ball. Yeboah (21) is the sole forward with more carries leading to shots and chances created than Adeyemi (21), though the Ghanaian's total comes from nearly 300 minutes more on the pitch.

It's a similar story in the Champions League. His carries led to a combined total of eight shots and chances created in the group stage – the only Opta-defined strikers to better that were Kylian Mbappe, Cristiano Ronaldo (both nine) and Arnaut Danjuma (14).

Even if it's reductive to just look at that metric, there's no doubt his performances have translated to European football's biggest stage – Sevilla's Diego Carlos will have been hoping to never see the youngster again after terrorising the Brazilian in the group.

Adeyemi's displays were a major factor in Salzburg reaching the knockouts of the Champions League for the first time in their history.

It would be a truly inspirational tale were it to be him, the young Bavarian cast-off, who plotted Bayern's downfall this time.

Bayern Munich were beaten by Bochum for the first time in 18 years after a crushing 4-2 defeat at Vonovia Ruhrstadion.

Despite a Robert Lewandowski brace, Julian Nagelsmann's side could not avert a surprise loss against their inspired opponents.

Christopher Antwi-Adjei, Jurgen Locadia, Cristian Gamboa and Gerrit Holtmann were all on target before half-time for the hosts, who had not netted four times in the Bundesliga since a 5-3 victory over Wolfsburg in November 2007.

Meanwhile, the leaders conceded four goals in the German top flight for the first time since a 5-1 loss to Eintracht Frankfurt in November 2019.

Bayern had won each of their past eight away games against Bochum and took the lead after just nine minutes, Lewandowski scrambling the ball home after Kingsley Coman cushioned Thomas Muller's cross neatly into his path.

But the runaway leaders led for just five minutes as Antwi-Adjei beat Sven Ulreich after latching onto Holtmann's sweeping pass.

The hosts completed the turnaround from the penalty spot, with Locadia sweeping home after Dayet Upamecano was penalised for handball.

Two became three when Gamboa played a neat one-two with Patrick Osterhage and arrowed a terrific shot into the far corner, before Holtmann made it four with a wonderful curling effort from 20 yards.

The hosts thought they had increased their advantage after the break, but Antwi-Adjei was denied by the offside flag.

Lewandowski pulled one back with a neat volley 16 minutes from time, but Bochum maintained their composure and discipline to seal a memorable win.

Bayern Munich head coach Julian Nagelsmann has no favourite for Super Bowl LVI and may well not be awake to take it in regardless.

The Los Angeles Rams take on the Cincinnati Bengals on Sunday in California, though it will be beyond midnight in Germany by the time the game starts.

This week, NFL commissioner Roger Goodell announced Germany would stage four NFL games over the next four seasons, starting from the 2022 campaign.

Indeed, it will be Bayern's Allianz Arena that hosts the first NFL regular-season game to be played in mainland Europe, with Frankfurt the other venue.

With the Super Bowl dominating headlines in the lead-up to this weekend, Nagelsmann was quizzed on his preference ahead of the Rams-Bengals clash.

"I don't have a favourite. My favourites have all been eliminated," Nagelsmann explained in a news conference on Friday.

"I don't have one favourite team. I have a connection to the Kansas City Chiefs, but I also find the Green Bay Packers interesting."

He then quipped: "Most of the time, when I watch the Super Bowl I fall asleep at halftime because I have a [lot of] work to do."

Asked if he is excited by the prospect of the NFL coming to Germany, following its success of staging games in London over recent years, Nagelsmann joked: "The anticipation in Germany is very great... when I get tickets!"

In total, five NFL regular-season games will be played outside the United States next season.

Three will take place in London, one in Munich and one in Mexico.

Julian Nagelsmann will be "sad" to see Niklas Sule leave Bayern Munich but reiterated that the centre-back remains a crucial player for the remainder of the season.

It was confirmed last month that Sule would not be signing a new contract with Bayern. His current deal expires at the end of 2021-22.

And despite links to several Premier League and LaLiga clubs, it was revealed on Monday that Sule had agreed to join Bayern's Bundesliga rivals Borussia Dortmund at the end of the campaign.

That decision was questioned by Bayern chairman Herbert Hainer earlier this week, as he queried why Sule would take what he views as a step down rather than go for a potentially more lucrative move to England or Spain.

Nagelsmann, however, has maintained his balanced view of the situation, having recently defended Sule following criticism from Bayern great Karl-Heinz Rummenigge.

"I don't judge it at all because it's not my decision, it's not my life," he told a news conference ahead of Bayern's game with Bochum. 

"Of course I'm sad because I've been with him for a long time. These are normal processes in football, that players leave us on a free transfer.

"But we still have to get along and make it clear that Niklas is still our player until June 30, and we want the title with greed.

"I can understand that fans are frustrated. Sometimes you win, sometimes you lose."

Sule joined Bayern from Hoffenheim in 2017 and has made 159 appearances for the club, winning four Bundesliga titles and two DFB-Pokal crowns, as well as the 2019-20 Champions League.

This season, he has played in 19 Bundesliga games, making 21 interceptions and winning 31 aerial duels.

Asked if Tanguy Nianzou, a 19-year-old who joined Bayern from Paris Saint-Germain in 2020, may step up to replace Sule next season, Nagelsmann replied: "Tanguy is a talent, but he's getting to an age when he has to play consistently. 

"There are moments when he plays outstandingly, then there are moments when he plays hair-raising bad passes. That's certainly due to the lack of rhythm.

"The coach has to take responsibility for that, but that creates a vicious cycle, you don't get any game practice and therefore no consistency.

"He has a very great asset and that is his aggression and his unconditional will to defend. Now he has to work on his consistency."

Nianzou has made just 21 appearances for Bayern so far, with just four of those being starts.

Things have not quite gone to plan for Cristiano Ronaldo in his second coming at Manchester United.

The Red Devils are out of both domestic cup competitions and sit well off the pace of Premier League leaders Manchester City, making an unlikely Champions League triumph their remaining hope for silverware this season.

Ronaldo is enduring a five-game goal drought and, according to a report, he could choose to end his second United spell after only one season.

TOP STORY – RONALDO WANTS MENDES TALKS OVER FUTURE

Cristiano Ronaldo will speak with his agent after growing disillusioned with life at Manchester United, according to the Daily Star.

The forward is hoping to speak with Jorge Mendes when he is back in Portugal for March's World Cup play-off against Turkey about his options after the end of the season.

Ronaldo, whose contract runs until the end of 2022-23, wants to see who will be appointed as United's next permanent manager – but he is not in favour of giving the job to interim boss Ralf Rangnick.

ROUND-UP

- Paul Pogba is also looking to leave Manchester United this year when his contract expires, but he will have to accept a pay cut to get a move abroad that he wants, the Mirror says.

- A possible replacement for Pogba could be Youri Tielemans. Het Nieuwsblad reports Leicester City have dropped their asking price for the midfielder, who is wanted by United and Arsenal.

- Real Madrid rejected the idea of signing Dusan Vlahovic, now at Juventus, because they are putting everything into getting Paris Saint-Germain star Kylian Mbappe, says Cadena Ser.

- However, AS reports Madrid are still seriously interested in Borussia Dortmund's Erling Haaland, which could scupper Robert Lewandowski's hopes of moving to the Spanish capital.

- Juve defender Matthijs de Ligt is flattered by interest from Chelsea and Barcelona, Sport Mediaset claims.

- Barca are also desperate to sign Haaland and will therefore prioritise cut-price deals for defenders, says ESPN. Chelsea trio Cesar Azpilicueta, Andreas Christensen and Marcos Alonso are on their shortlist.

Bayern Munich chairman Herbert Hainer has questioned Niklas Sule's decision to leave the club at the end of his contract to join Borussia Dortmund.

Dortmund announced on Monday a pre-agreement is in place with the Germany defender, who will join the club from Bayern at the end of the season.

The 26-year-old has agreed to a four-year deal at Signal Iduna Park, having decided against extending his Bayern contract, which expires at the end of 2021-22.

However, Hainer has questioned Sule's decision to choose Bundesliga rivals rather than potentially more lucrative offers from the Premier League and LaLiga.

"He was already being discussed at Dortmund and there was speculation – in addition to Real Madrid, Manchester City and a few others – but I hadn't thought that it would be his first choice," Hainer told Bild.

"It will be exciting to see him on the other side. But it's not new to us either. We also gave Mats Hummels to Dortmund.

"I don't know what salary Niklas Sule gets at Borussia Dortmund. But I don't think it's a sporting climb.

"Niklas is a very good player who has become a regular in the national team in the last five years. I'm assuming that he'll really give it his all over the next three months so that he can still clinch the titles that we have ahead of us."

Sule joined Bayern from Hoffenheim in 2017 and has made 159 appearances for the club, winning four Bundesliga titles and two DFB-Pokal crowns, as well as the 2019-20 Champions League.

However, when it emerged he would not be signing a new contract, former Bayern star and chairman Karl-Heinz Rummenigge claimed the centre-back "never really asserted himself in his position" while at the club.

Sule's agent, Volker Struth, recently said his client "didn’t feel fully valued" by the German champions.

"I can only speak of myself and the people I am with every day," Hainer said in response to those comments.

"We all appreciated him and know what we had and still have in him. You have to ask him yourself what exactly he means by that."

Borussia Dortmund have announced the signing of defender Niklas Sule, who will join the club from Bayern Munich at the end of the season.

The 26-year-old has agreed to a four-year deal at Signal Iduna Park, having decided against extending his Bayern contract, which expires at the end of 2021-22.

"We're delighted that we have managed to sign Niklas Sule, a Germany international, on a free transfer and have tied the player down for four years," said Dortmund sporting director Michael Zorc.

Sebastian Kehl, who will succeed Zorc later this year, added: "Niklas has shown during the course of personal talks that he is really keen on Borussia Dortmund.

"He possesses a lot of experience, composure in his build-up play and the necessary physicality to take the next step with us from this summer onwards."

Sule joined Bayern from Hoffenheim in 2017 and has made 159 appearances for the club, winning four Bundesliga titles and two DFB-Pokal crowns, as well as the 2019-20 Champions League.

However, when it emerged he would not be signing a new contract, former Bayern star and chairman Karl-Heinz Rummenigge claimed the centre-back "never really asserted himself in his position" while at the club.

Ex-Bayern captain Stefan Effenberg accused Sule of chasing money over sporting success as interest from Chelsea and newly rich Newcastle United was reported.

Sule's agent, however, told Sport1 that the player simply wanted a new challenge.

Manuel Neuer will miss at least the first leg of Bayern Munich's Champions League last-16 clash with Salzburg after undergoing knee surgery.

Bayern said their long-serving goalkeeper would be sidelined for several weeks, with the Bundesliga leaders disclosing the unexpected news on Sunday evening.

In a statement, Bayern said: "Manuel Neuer underwent successful surgery on his right knee joint on Sunday. FC Bayern will therefore have to do without their captain for the coming weeks."

Hasan Salihamidzic, the Bayern sporting director, said: "All of us in the club and the team wish Manuel a good and speedy recovery, and we're sure he'll be back to full fitness with us soon."

Sven Ulreich has been Neuer's deputy and is expected to step in while the 35-year-old regular number one rehabilitates.

Bayern are next due in action when they face Bochum in the Bundesliga next Saturday, before they travel to Salzburg for the first leg of their European tie on the following Wednesday.

The second leg of that tie is due to take place on March 8, and it remains to be seen whether Neuer will be passed fit for that game. Neuer has already indicated he is hopeful he will be available to head coach Julian Nagelsmann by then.

Neuer wrote on Instagram: "Hey guys, I had a little surgery on my knee this afternoon. Everything went fine, so I'll be able to start rehabilitation training soon. Keep your fingers crossed that I'll be back on the pitch in a couple of weeks."

On Saturday, Neuer helped Bayern earn a 3-2 home win over Leipzig, as he matched Oliver Kahn's all-time record of 310 Bundesliga wins by a player. He achieved the first 77 wins with Schalke, before joining Bayern in 2011.
