Robert Lewandowski's injury is an example of "situations you have as a coach" for Hansi Flick, who vowed to face the challenge of coping without Bayern Munich's talisman head on.

The prolific Poland striker is facing up to the prospect of a month on the sidelines after damaging knee ligaments in his country's 3-0 win over Andorra.

It is a cruel blow for Lewandowski, who has 35 goals in the Bundesliga and looked well on course to at least match Gerd Muller's famous record of 40 in a single campaign, set back in 1971-72.

The 32-year-old is unavailable for this weekend's crunch clash with second-place RB Leipzig and will miss both legs of the Champions League quarter-final with Paris Saint-Germain.

For Flick, though, dealing with adversity is par for the course.

"These are situations that you have as a coach. I'm sorry for the player who got injured. I would like to have everyone with me," he told a pre-match news conference.

"There is no question that Robert is important to us. We have players who can play in that position. It is a challenge for all of us that we are happy to face. We only know roughly when Robert will be back. It's hard to say in detail."

Asked if Eric Maxim Choupo-Moting could be afforded the opportunity to play in Lewandowski's absence, Flick replied: "Choupo is a player who shows his quality in training and in matches. 

"I leave it open to me how we play. But it is definitely an option."

The return to domestic action comes after another busy international break and precedes the Champions League quarter-finals.

Flick understands that the difficulties caused by the coronavirus pandemic have made such scenarios inevitable but says thought should be given on how to protect player welfare.

"At the moment there is no alternative. An association also needs its games. There is a lot that has to do with it," he added.

"The players are under a lot of stress - last season, this season, next season won't be any different. 

"Stress management is a topic that teams need to be aware of. But also the national teams. It's not easy because everyone has their goals. But at some point a limit of resilience is reached. One should think about it."

Bayern travel to Leipzig on Saturday four points clear of their nearest rivals with eight games to play but Flick was reluctant to declare the fixture as decisive in the race for the title.

"I'll worry about that when the game is over," he added. "It's a top-level game."

News of Robert Lewandowski being ruled out for a month on Tuesday left many feeling the pendulum might have swung in RB Leipzig's favour in the Bundesliga title race.

Enjoying another phenomenal season, the Poland striker has been irresistible for reigning champions Bayern and had come to within touching distance of history.

With 35 league goals in just 25 matches, Lewandowski was just five strikes from equalling Gerd Muller's all-time single-season record – no one has matched that haul since the Bayern and West Germany great achieved it in 1971-72.

Although already seemingly certain to be regarded as a Bundesliga icon long after he hangs up his boots, eclipsing such a feat while well into his thirties would have surely elevated his legend to a whole new level in German football history.

Who knows, he may yet reach it this term. Assuming he is out for exactly four weeks, the time period Bayern themselves specified, netting another six in Bayern's final three league games is by no means beyond Lewandowski given the rate he had been scoring at.

But without suffering his knee injury against Andorra, he would have had eight league matches to reach that figure, while his absence will also surely impact on the collective for Bayern.

Hansi Flick's men are top but only have a four-point cushion ahead of RB Leipzig, whom they will hosted by on Saturday in a game that could have decisive ramifications on the title race.

But Leipzig cannot fall into the trap of taking the absence of Lewandowski – whose xG overperformance of 8.8 for non-penalty goals (29 scored, 20.2 xG) is unmatched across Europe's top five leagues – for granted.

"Basically, Bayern still has a lot of good players even if Robert Lewandowski will be missing the game," Leipzig sporting director Markus Krosche told Stats Perform News. "They can replace him.

"Of course, he is a very important player for them after having scored 35 goals, but the squad is good enough to replace him. That's still not our focus.

"We have to focus on ourselves and what happens on the pitch because that's what counts for us. If we push ourselves to the limit, then we have a great possibility to beat them. It doesn't matter if they play with or without Lewandowski."

Victory for Bayern in Leipzig will see them take a huge step towards a ninth successive Bundesliga title and the omens aren't great for Julian Nagelsmann's side, having won just once in 11 competitive meetings with Bayern.

But Die Roten Bullen head into the weekend unbeaten in eight league games, a run that's seen them amass 22 from a possible 24 points and subsequently claw themselves back to within just a few points of Bayern.

"I am pretty proud," Krosche replied when asked how if felt to be Bayern's main rival in 2020-21. "But not only because we are second in the league and their closest rival, but also the way we have been playing in the last few months makes me proud.

"The boys did a great job and have developed well. The way we play is one of the best styles in the Bundesliga, and it is because of our playing style that we could achieve these results. I am proud about the development of the boys.

"We need to keep doing the same things just like in the last few weeks and months. We need to show this football on the pitch. Of course, we need to push ourselves to the limit against Bayern, but we have a lot of self-confidence.

"Our playing style is really good and the boys are convinced of our idea of how to play. So, we'll try to reach our maximum and then we have a good chance to beat them."

Stopping Bayern as an attacking threat will be half the battle on Saturday, as Die Roten are averaging three goals every game in the Bundesliga and haven't fired blanks in any of their previous 61 matches across all competitions, equalling a club record. Coincidentally, Leipzig were the last team to shut them out in February last year.

Despite such a remarkable run, Bayern have not been immune to criticism and the fact they aren't yet cruising at the top has led to suggestions of the champions being a shadow of their former selves, and losing Lewandowski for a month won't help.

But Krosche is adamant talk of a Bayern with "weaknesses" has been over the top, instead surmising the chasing pack has improved, with Leipzig boasting the best defence in the league (21 conceded). He said: "Bayern have not played a bad season. People say that they have some weaknesses this season but that's not the case.

"I think it's basically the case that we are doing very well. We have a very good balance between offence and defence. That's what makes us strong this season, and that's the reason why we are so close to Bayern right now.

"What will be decisive on Saturday is how we can find the balance. This is our plan and we'll try to do it. I don't want to reduce it to 'Bayern are having weaknesses' but rather say that we are consistent this year and that we have a good opportunity to move even closer when we beat them."

Beyond the potential impact on the title race, Saturday will be a particularly intriguing contest for Dayot Upamecano, who has already agreed to join Bayern at the end of the season. Krosche hopes he can succeed in Munich but was non-committal on projecting the Frenchman's future at the Allianz Arena.

"Upa is a player that has everything you need. He is a young guy who already has a lot of international experience," he continued. "As I said, he's got everything. He is an important player for us. He has a bright future ahead.

"I don't know what will happen at Bayern next season. He has a lot of potential for further development, but we will see. We are happy that he is still with us and we hope that we can be successful this season with him. Then we will see how he performs at Bayern."

One thing's for certain, Upamecano will be relieved to know the next time he has to come up against Lewandowski will only be a training session.

Robert Lewandowski could have missed his chance to break Gerd Muller's record for goals in a single Bundesliga season, former Bayern Munich forward Roy Makaay says.

Poland striker Lewandowski suffered knee ligament damage in the 3-0 World Cup qualifying win over Andorra and is facing a month out of action.

The 32-year-old will miss both legs of the Champions League quarter-final with Paris Saint-Germain and most likely league matches against RB Leipzig, Union Berlin, Wolfsburg, Bayer Leverkusen and Mainz.

With 35 goals scored in the first 25 matchdays of the Bundesliga season, Lewandowski had looked almost certain to match Muller's famous landmark of 40, set back in 1971-72.

However, given the league leaders have only three matches remaining after they face Mainz on April 24, Makaay thinks the record could have slipped beyond Lewandowski's reach.

The former Netherlands international is also concerned about the options available to coach Hansi Flick when it comes to finding a replacement striker.

"For me, Lewandowski has been the best centre-forward in the world for years. What he does inside and outside the penalty area as a number nine is unbelievable," he told Spox.

"It certainly won't be easy [now] for Lewandowski to break the record. This absence is not good news for Bayern. As for his replacement, you'd have to make that [decision] dependent on the opposition. [Serge] Gnabry is more agile than [Eric Maxim] Choupo-Moting."

However, Makaay remains convinced Lewandowski has plenty yet to offer Bayern in seasons to come, suggesting there would be no pressing need to try to sign Borussia Dortmund sensation Erling Haaland.

"Anyone who scores so consistently at that age can only have a great future ahead of them," Makaay said of the Norway star. "But Lewandowski still has a few very good years ahead of him, I'm sure of that."

Makaay, twice a domestic double winner with Bayern, would have relished the chance to play alongside Lewandowski but also identified two other key players he feels would have made his life as a forward easier.

"Lewandowski and I would certainly have made a good partnership, but I'd also have liked to play with a guy like Thomas Muller," he said.

"The person I really like as a personality is Joshua Kimmich. You want a player like that behind you as a striker. In my time, we had Michael Ballack and later Schweini [Bastian Schweinsteiger] – they weren't too bad, either."

England boss Gareth Southgate expects Poland to be highly motivated for Wednesday's World Cup qualifier at Wembley in the absence of captain and leading goalscorer Robert Lewandowski.

The Bayern Munich striker sustained a knee injury in Sunday's 3-0 win over Andorra - a game in which he scored twice - and it was confirmed by his club on Tuesday that he will miss the next month.

Lewandowski has scored 66 goals in 118 appearances for Poland, including nine goals in his last nine starts in all competitions.

But Southgate rejected the notion that England will be boosted by the prolific striker's absence for the clash between Group I's top two seeds.

"From our perspective, you're going to have players who are hungry to fill that opportunity," Southgate said at a pre-match news conference on Tuesday.

"They're a good side with some good players. They will all fight for the cause and they're a good football team. They've got high motivation. 

"We've got to keep improving. We've shown a good level and we've got to keep stepping up.

"I understand the question, but I think Poland have excellent players. We would be naive to think they are less of a threat. 

"If we think of taking our foot off the gas, we'll get hurt. Of course, the public want to see the star names, but a team isn't about one player."

England will be looking to make it three wins from three in their March fixtures after following up a 5-0 win over San Marino with a 2-0 victory in Albania on Sunday.

Mason Mount was among the scorers in Tirana and has enjoyed an impressive campaign at club level with Chelsea.

He has played the most minutes of any Chelsea player (2,231) this term, while his 69 chances created is 41 more than anyone else. 

The 168 passes Mount has played into the opposition box is also by far the most among Chelsea players, form that he has carried over onto the international stage.

There had been doubts over the midfielder's fitness after he sat out part of training on Tuesday, but Southgate expects to have one of his key men available for the visit of Poland.

"He didn't warm up with the team but he did the rest of the session with his team-mates," Southgate said. "He should be fine. They are all available as far as we are aware.

"We've managed the team through the matches and the training sessions. We've been very cautious. We've got to balance that freshness. 

"We were very happy with the performance the other day. Around Europe, most countries have taken a similar slant."

Poland may be without their leading marksman for the game, but England have a fit and firing Harry Kane to lead their line.

The Tottenham striker's club future has been the subject of much speculation during the international break, but Southgate reiterated his captain will not be distracted by the rumours.

"He's so focused. I had a chat with him and he's very positive about the club," Southgate said. 

"He was talking about being a few points off the Champions League, into the EFL Cup final. I've got no worries about Harry Kane. He's a fantastic professional.

"Harry is highly motivated. All players want to win. He's got an opportunity with his club to do that."

Kane has scored on six days of the week for England but has never managed to do so on a Wednesday, failing in three different games on that day so far. 

Only Frank Lampard and Wayne Rooney have scored on all seven of the days of the week for the Three Lions.

Robert Lewandowski will miss both Champions League quarter-final clashes with Paris Saint-Germain after Bayern Munich confirmed he is to be sidelined for a month with a knee injury.

Lewandowski sustained damage to his right knee during Poland's 3-0 World Cup qualifying win over Andorra on Sunday, a game in which he scored twice.

Poland subsequently confirmed he was to play no part in the upcoming clash with England and that he was due to return to Bayern for treatment.

It was initially thought the 32-year-old would only be absent for up to 10 days, however, Bayern confirmed on Tuesday that the issue is slightly more serious than first suspected.

A statement revealed Lewandowski is now expected to be out for most of April.

It read: "Robert Lewandowski has strained a ligament in his right knee. The FC Bayern striker will be out for around four weeks.

"After Poland's 3-0 win over Andorra, Lewandowski returned early to Munich, where a diagnosis was made by the German record champions' medical team."

While losing Lewandowski for so long would be a major blow regardless of the opponents Bayern have lined up, his forced absence comes at a particularly critical moment in the season.

The reigning Bundesliga champions face title rivals RB Leipzig this weekend, before meetings with PSG in the Champions League either side of Union Berlin's visit.

Those contests with PSG will be repeats of last season's Champions League final, which Bayern emerged from as 1-0 victors last August.

Losing Lewandowski will cause Bayern significant concern in attack, with their squad not possessing another senior central striker, meaning either Thomas Muller will be moved in to deputise or Eric Maxim Choupo-Moting will take on a more important role for the time being.

On a personal level, losing a month of the season could derail Lewandowski's hopes of breaking Gerd Muller's record of 40 goals in a single Bundesliga campaign.

The former West Germany star achieved the feat in 1971-72 with Bayern and Lewandowski is just five adrift, having netted 35 in 25 games this term.

Assuming Lewandowski is out for exactly four weeks, he will have three matches to score five or more goals – those games coming against Borussia Monchengladbach, Freiburg and Augsburg.

Robert Lewandowski will miss both Champions League quarter-final clashes with Paris Saint-Germain after Bayern Munich confirmed he is to be sidelined for a month with a knee injury.

Lewandowski sustained damage to his right knee during Poland's 3-0 World Cup qualifying win over Andorra on Sunday, a game in which he scored twice.

Poland subsequently confirmed he was to play no part in the upcoming clash with England and that he was due to return to Bayern for treatment.

It was initially thought the 32-year-old would only be absent for up to 10 days, however, Bayern confirmed on Tuesday that the issue is slightly more serious than first suspected.

England could be without Mason Mount for Wednesday's World Cup qualifier against Poland at Wembley.

Mount was absent from Tuesday's training session, with the Chelsea midfielder undergoing work with the medical and performance team, though no injury details were revealed.

It would represent a blow to England, with Mount having scored in Sunday's 2-0 win over Albania.

That result made it back-to-back victories for the Three Lions in Group I, in which Poland likely pose their greatest threat.

Mount has been a key man for Chelsea this term, playing more minutes (2,231) than any of his team-mates, while his 69 chances created is 41 more than anyone else. 

He has been a creative pillar for the Blues, as further evidenced by his 168 passes into the box being by far the most among Chelsea players, while the fact he quickly won his place back after being left out for Thomas Tuchel's first game in charge speaks to his impressive mentality. 

Poland suffered a huge injury setback of their own when record goalscorer Robert Lewandowski was forced to return to Bayern Munich to receive treatment on a knee injury.

The striker sustained damage to the collateral ligament of his right knee during the 3-0 win over Andorra, in which he scored twice.

Poland issued a statement on Monday to confirm Lewandowski would miss Wednesday's match in order to avoid the risk of aggravating the injury.

The 32-year-old has instead returned to Germany for further treatment, which is expected to last from five to 10 days.

Poland have also lost Grzegorz Krychowiak and Kamil Piatkowski, who become the latest players to test positive for coronavirus.

Midfielder Mateusz Klich was the first squad member to return a positive COVID-19 test last week and it was revealed on Saturday that goalkeeper Łukasz Skorupski had also contracted the virus.

Robert Lewandowski has returned to Bayern Munich to receive treatment on a knee injury, Poland have confirmed.

The striker sustained damage to the collateral ligament of his right knee during the 3-0 World Cup qualifying win over Andorra, in which he scored twice.

Poland issued a statement on Monday to confirm Lewandowski will miss their match with England on Wednesday in order to avoid the risk of aggravating the injury.

The 32-year-old will instead return to Germany for further treatment, which is expected to last from five to 10 days.

The news will be of concern to Bayern coach Hansi Flick ahead of a tough run of fixtures for the Bundesliga leaders.

Bayern face RB Leipzig on April 3, four days before the first leg of their Champions League quarter-final against Paris Saint-Germain.

The German champions then host Union Berlin on April 10 ahead of the return leg away to PSG on April 13.

Lewandowski has scored 42 goals and provided eight assists in 36 appearances in all competitions for Bayern this season.

The former Borussia Dortmund star has at least 10 more direct goal involvements in 2020-21 than any other Bundesliga player.

Alphonso Davies' early red card "woke up" Bayern Munich and set them on their way to claiming a 4-0 victory over Stuttgart despite their numerical disadvantage, Robert Lewandowski has declared.

The Bundesliga champions had been on the back foot even prior to losing their left-back in the 12th minute for a poor challenge on Wataru Endo.

But they responded brilliantly, taking the lead through hat-trick hero Lewandowski before Serge Gnabry also scored as they built a four-goal lead by half-time.

Speaking after the game, the Poland star shared his belief that, rather than hurt Bayern, the dismissal actually served to bring them to life.

He said: "We played really well after the red card. That woke us up. Before that, we didn't play so perfectly.

"After that, it was a challenge for us to create chances and score goals. We wanted to keep playing forward after the first goal and try to add another one."

Bayern coach Hansi Flick was understandably full of praise for the manner in which his players responded to that setback.

The German also had no complaints about the decision to dismiss his player.

"I have to give my team a huge compliment," he enthused.

"After the dismissal, which was justified, they worked well on the defensive, made the spaces very, very tight as a team and did very well in possession of the ball, especially in the first half.

"The way we created the chances was simply outstanding. We had to change the defence today and were very compact.

"We kept the clean sheet and got the three points – that was our goal and thus a successful game day for us."

As for Stuttgart boss Pellegrino Matarazzo, he felt the sending-off only ended up taking away the visitors' positive early momentum.

He said: "We got into the game well, you can even say that we were dominant.

"We played well and should have taken the lead shortly after the red card. Then something happened mentally: either that we had pressure to win or we thought we had less pressure now.

"We paid in the first half and I hope we can do better next time."

Robert Lewandowski scored a second consecutive home hat-trick in the Bundesliga as 10-man Bayern Munich thrashed Stuttgart 4-0 to extend their lead at the summit to four points.

The Pole, who found the back of the net threes time against Borussia Dortmund on his last league outing at the Allianz Arena, took just 39 minutes to repeat the feat here.

Serge Gnabry also got on the scoresheet in a rampant first half as Hansi Flick's side brushed off the early loss of Alphonso Davies to a red card to claim a thumping victory.

Davies received his marching orders after VAR intervened to upgrade a yellow for his studs-up challenge on Wataru Endo.

After surviving an early storm, Bayern went ahead through Lewandowski, who claimed second place in the Bundesliga's all-time top scorer charts outright by powering in Gnabry's low cross to bring up his 269th goal in the competition.

Provider then turned goalscorer as Gnabry benefited from a slick exchange between Thomas Muller and Leroy Sane to finish a wonderful team goal.

A minute later, Lewandowski's powerful header from Muller's right-wing cross had Bayern three ahead with barely a quarter of the game gone.

And the prolific Pole had a hat-trick just before the break, pinching the ball inside the box and arrowing a left-footed finish into the bottom right-hand corner to make it three goals from three shots.

Bayern's number nine should have made it four just past the hour mark but miscued in uncharacteristic fashion after being picked out by Benjamin Pavard's low cross.

But that miss mattered little in the end as the champions saw out their win with little discomfort.

What does it mean? History beckons for Lewandowski

Having already scored more Bundesliga hat-tricks than any other player in history, Lewandowski added a 13th here to extend his lead over Mario Gomez (10) to three.

The Pole is now on 35 league goals for the season and will surely have his sights set on breaking Gerd Muller's record of 40 in a single campaign in the German top-flight in the eight remaining games.

In fact, 'Der Bomber's' outright scoring record of 365 does not look out of reach for a player who is now on 271 and, at the age of 32, still looks to have plenty of years at the top level left in him.

Lewa stars for Bayern

Bayern had been up against it even prior to losing Davies, but the complexion game changed entirely when Lewandowski took his first goal in brilliant fashion.

That the Poland international grabbed his hat-trick from just three shots says everything about his quality in front of goal.

Davies errs again

But for the brilliance of Lewandowski, Davies' rash early challenge could have put his teammates in for a difficult afternoon.

The Canadian had already given the ball away four times in just 12 touches across an uncertain start, and will now miss the crucial showdown with RB Leipzig next time out due to suspension.

What's next?

Bayern Munich could take a big step toward to retaining the Bundesliga title when they face nearest challengers Leipzig in two weeks. A win would take Flick's men seven points clear with as many games remaining, while defeat would close the gap to just a single point.

As for Stuttgart, they will hope to get their push for European football back on track when they host Werder Bremen.

Robert Lewandowski revealed it would mean "a lot" to break Gerd Muller's long-standing record for most goals scored in a single Bundesliga season.

The Poland striker has registered 32 goals from 25 matchdays in Germany's top flight this season, meaning he needs nine more to overhaul the benchmark of 40 set by fellow Bayern Munich legend Muller in the 1971-72 season.

Last season, Lewandowski netted in his opening 11 league matches but ultimately fell six shy of Muller's tally, even though his form propelled Bayern to a Bundesliga, DFB-Pokal and Champions League treble and helped him to win the best men's player at the Best FIFA Football Awards.

Asked by Sport Bild what it would mean to break the record, Lewandowski replied: "A lot.

"[But the target of] this unique club legend is far away, I don't want to worry too much.

"[If I get] one or two goals behind the 40 goals topic would be intense in my head.

"It would fill me with incredible pride. But Gerd Muller will always be Gerd Muller – [he is] unmatched.

"I might have a bit of mental stress: reaching this mark after almost 50 years would mean a lot to me."

Lewandowski's 32 league goals this season is far clear of the 19 scored by Erling Haaland and Andre Silva, who are next on the list.

The Poland striker also tops the rankings for shots on target (51) and 'big chances' scored (23), while his goal in Saturday's 3-1 win over Werder Bremen was his 268th in the Bundesliga moving him joint-second on the all-time list with Klaus Fischer. 

Nowadays, Lewandowski is the man young strikers are aspiring to be like, but the 32-year-old said Roberto Baggio, Alessandro Del Piero and Thierry Henry were among those he looked up to when trying to hone his talents.

"When I was six years old, there was only one idol for me: Roberto Baggio," he added.

"Alessandro Del Piero later became my role model in football, and I admired him. However, I was not yet able to judge exactly what characterises his style of play, I was just too young for that. 

"It later became Arsenal legend Thierry Henry. His movements, the runs in depth, the finishes – as a young footballer these were the qualities I wanted to have. I wanted to imitate everything Henry did."

Robert Lewandowski moved joint-second in the Bundesliga's all-time top scorers list as Bayern Munich claimed a 3-1 win over Werder Bremen on Saturday.

The Pole matched Klaus Fischer's tally of 268 goals as he joined Leon Goretzka and Serge Gnabry on the scoresheet in a comfortable win that extended the champions' lead at the summit to five points.

Lewandowski now needs another 97 goals to match Bayern legend Gerd Muller's incredible tally of 365.

Werder were given hope that they might put the champions under pressure when Ludwig Augustinsson produced the first shot on target of the match, cutting in before releasing a weak right-footed effort.

But it was all Bayern from there, with Gnabry and Joshua Kimmich signalling the visitors' intent as they each fired just over the bar in quick succession.

Bayern Munich have rarely been shy about coaxing players to cross the divide and make the move from Der Klassiker rivals Borussia Dortmund.

Their willingness to do so ensured Dortmund's last spell at the top of German football, when a vibrant young side gegenpressed their way to a Bundesliga and DFB-Pokal double in 2011-12 and a Champions League final a year later, was an ephemeral one, Robert Lewandowski and Mario Gotze each making the move to Bayern in 2013 and experiencing varying degrees of success.

And the build-up to the most famous fixture in Germany was partially defined by Bayern seemingly beginning a charm offensive to attract one of Dortmund's most prized assets, Erling Haaland, to eschew potential moves elsewhere in favour of following Lewandowski's path.

"Haaland is what a centre-forward has to be," Bayern coach Hansi Flick said in his pre-match media conference. "He has an enormous hunger for goals. The future could belong to him because he has everything he needs for it."

The Norway forward's agent, Mino Raiola, has claimed only 10 clubs in the world would be able to afford to sign Haaland, who has a release clause that does not become active until 2022.

But Bayern president Herbert Hainer told Sport1 this week: "We will go even more down our successful path of signing young players with outstanding skills. We are an economically very strong and healthy club.

"Although we're also suffering massively from the pandemic, we can always bring in players when we're convinced about them."

Bayern clearly have no doubts about their financial capability to sign Haaland, and they may be convinced to make a concerted push to do so after his first-half salvo in Saturday's Klassiker, which forced Flick's men to produce a stirring comeback.

Haaland had two games without a goal prior to Dortmund's trip to the Allianz Arena.

He ended that 'drought' in the space of a minute and 14 seconds, taking a few touches to steady himself on the edge of the Bayern box and power an effort that deflected off Jerome Boateng beyond Manuel Neuer and into the bottom-right corner.

Fewer than eight minutes later, he made it 2-0, his goalscorer's instinct again shining through with a much more simple finish as he popped up in the box to turn home Thorgan Hazard's pull-back from point-blank range at the end of a wonderful Dortmund move.

His double took his tally against Bayern for the season to four goals, but he would ultimately be denied the chance to become the first player since Cristiano Ronaldo (5) in 2016-17 to score more than four in a season versus Die Roten.

A second-half ankle injury forced Haaland off, the looming second leg of their Champions League last-16 tie with Sevilla likely playing a role in his withdrawal on the hour.

That blow followed a first-half fightback from Bayern, which was fuelled by a predictable source in Lewandowski, who diverted a shot-turned-cross from Leroy Sane into the net before rolling home a penalty after Mahmoud Dahoud's foul on the ever influential Kingsley Coman, taking his tally of Bundesliga goals against Dortmund to a league-record 19.

Dortmund's rearguard action in a one-sided second half looked set to frustrate Bayern and keep RB Leipzig top of the Bundesliga.

But their resilience wilted late on, Schalke product Leon Goretzka hitting home on the volley in the 88th minute and Lewandowski making it 20 against his former club by completing his hat-trick with an unerring finish from the edge of the area.

It was the kind of rapid collapse from Dortmund that illustrated why Haaland, having hastily adapted to life in the Bundesliga following his move from Salzburg last year, could be keen to make a swift departure to a team better prepared to compete at the sharp end of European football, even with the highly touted Marco Rose set to take over as coach next season.

Dortmund are four points behind Eintracht Frankfurt in the race for the top four, and have a fight on their hands if they are to secure Champions League qualification for next season.

Haaland appeared set to steal the show 10 minutes into this storied fixture, but his 20-touch contribution was ultimately overshadowed by the man who reigns supreme as the Bundesliga's most potent goalscoring threat.

With Lewandowski maintaining this kind of form, Bayern have no rush to find the successor for a player under contract until 2023.

But after Haaland produced two goals from a game where had four touches in the box, his supporting role in the latest thrilling episode of this classic rivalry could compel Bayern to open the chequebook and add to what is arguably European football's most extensive embarrassment of riches.

Robert Lewandowski outscored Erling Haaland with a Klassiker hat-trick as Bayern Munich recovered from two goals down to again beat Borussia Dortmund in a 4-2 victory.

Bayern reclaimed top spot in the Bundesliga hours after being knocked off the summit by RB Leipzig, despite an awful start to another epic encounter on Saturday.

The champions were two behind inside nine minutes following Haaland's brace, but Lewandowski had them level by half-time and Dortmund, already missing Jadon Sancho, saw their two-goal talisman hobble off with half an hour to play.

BVB still looked set to hold on and end a run of four league defeats to Bayern, only for Leon Goretzka to break their resolve before Lewandowski's treble-clincher capped another outstanding outing.

Bayern Munich coach Hansi Flick made no secret of his admiration for Borussia Dortmund's Erling Haaland ahead of Der Klassiker, backing the Norway international to dominate the future of the sport.

Haaland has enjoyed a rapid rise since establishing himself as first choice at Salzburg for the start of the 2019-20 season, his remarkable haul of 28 goals in just 20 matches for the Austrians propelling him to top of many big clubs' transfer shortlists.

But, while the likes of Manchester United were keen on Haaland, Dortmund persuaded him to make the move to Signal Iduna Park, where he has been an overwhelming success.

In 45 matches across all competitions, Haaland has 43 goals, while he outperformed his xG (expected goals) by 4.2 in the second half of 2019-20 after joining Dortmund, meaning not only is he scoring frequently but he is also finishing more difficult opportunities – by comparison, Robert Lewandowski has not boasted such a strong xG differential since 2016-17 (7.8).

In three previous games against Bayern – two in the Bundesliga and one in the DFL-Supercup – Haaland has two goals, but he is yet to end up on the winning side against them with BVB.

Nevertheless, Flick is well aware of the threat posed by the Molde youth product, with Bayern facing the prospect of potentially being replaced at the Bundesliga summit by RB Leipzig if Dortmund leave the Allianz Arena with all three points on Saturday.

"Haaland is what a centre-forward has to be," Flick said.

"He has an enormous hunger for goals. The future could belong to him because he has everything he needs for it.

"He's fast, has a strong finish and the right mentality. When you see the intensity with which he puts on a sprint over 80 metres – it's great. He's someone you always have to watch out for.

"It's very important to close the spaces for him. We have to cut off those passes to him."

Flick was also asked about the situation of backup goalkeeper Alexander Nubel, who arrived on a free transfer from Schalke last year having established himself as one of the world's most-promising young goalkeepers.

It was always seen as a potentially risky move for Nubel given the presence of Manuel Neuer, who has gone on to put his injury nightmares behind him and once again cement himself as Bayern's number one.

Nubel's agent recently underlined his client's frustration with the situation and suggested he would look to secure a loan move away from Bayern if things did not change, and Flick showed little sympathy in his response.

"Those are things that we talk about internally – we will have an exchange," Flick said. "But we have no business talking about that here.

"His point of view is his right. Alex knew what he was getting into when he came to Bayern Munich. My job as coach is to pick the players who are currently the best team. He played two games and now he's injured.

"The clear number one is Manuel Neuer."
