Hansi Flick hailed his side's "mentality" after they moved seven points clear at the Bundesliga summit with a 1-0 win over RB Leipzig on Saturday. 

Leon Goretzka's third goal in his last four top-flight games proved the difference at the Red Bull Arena as Bayern took a significant step towards a ninth consecutive Bundesliga title. 

It marked the 62nd consecutive match in which Bayern have found the back of the net, setting a new record in Germany football since the Bundesliga was founded in 1963. 

Bayern did not have it all their own way against Leipzig, who had 14 shots to their nine, and Flick acknowledged his side had to use all of their mental strength to claim all three points against their second-placed hosts. 

"It was a top game and Leipzig showed why they are right up there," he told Sky. "We were on the trigger right from the start. 

"We didn't play forward as we would have wanted, but the goal was played out nicely. Leipzig caused us some problems, but the morale and mentality of my players is really excellent."

Goretzka's goal was created by Thomas Muller, who has now been involved in 11 goals in his last 10 Bundesliga games (four goals, seven assists). 

The 31-year-old has not played for Germany since November 2018 after being deemed surplus to requirements by Joachim Low.

However, there have been growing calls for him to be recalled for the rescheduled Euro 2020 at the end of the domestic season. 

Flick praised Muller for his "sensational" campaign, but said he did not want to influence Low, who he was assistant to between 2006 and 2014.

"I don't have to interfere," he added. "Thomas Muller is playing a sensational season. He can be important for other teams too, but in the end it has to be decided by Jogi. 

"He pushes his team-mates again and again, also in training. I am glad that we have such players in our ranks."

No side leading the Bundesliga by at least seven points after 27 games has failed to go on and win the title, but goalscorer Goretzka is refusing to get carried away.

"There are still 21 points to be awarded," he said. "It was a big step, but not the decisive one."

Bayern host Paris Saint-Germain in the first leg of their Champions League quarter-final on Wednesday before welcoming Union Berlin to the Allianz Arena in the Bundesliga four days later.

Hansi Flick will not be leaving his post at Bayern Munich any time soon, according to the Bundesliga giant's chief executive Karl-Heinz Rummenigge.

Flick, who won a remarkable sextuple in his first year as Bayern's head coach, has been mooted as the DFB's preferred successor to Joachim Low, who will end his tenure as Germany boss following this year's Euros.

The 56-year-old was Low's assistant coach for almost eight years, from August 2006 to July 2014, leaving his role after Germany's World Cup triumph.

Bayern have been the form side in Europe in Flick's time in charge, and despite a shock exit in the DFB-Pokal earlier this season, are still well in the hunt for a Bundesliga and Champions League double.

Robert Lewandowski scored a first-half hat-trick as Bayern made it six wins on the bounce on Saturday by thrashing Stuttgart 4-0, with a potentially decisive top-of-the-table clash with RB Leipzig up next after the international break, before the Bavarians take on Paris Saint-Germain – who they beat in last year's final – in the Champions League.

However, amid the speculation over who will take over from Low, Rummenigge has insisted Flick is going nowhere.

"I told him that we are very satisfied with him," Rummenigge told German publication Welt am Sonntag when asked about Flick's future.

"We are well advised to finish what we have agreed in the contract. I told Hansi that in no uncertain terms.

"[This has] nothing to do with probability. That is a fact."

On Saturday, Low hailed Flick as a potentially perfect candidate to replace him, though when asked for his thoughts on Low's praise, Bayern's coach replied: "It hasn't changed anything about the whole thing. There's nothing more to say about that."

Flick is under contract with Bayern until 2023, and Rummenigge also claimed that the DFB had confirmed they do not wish to appoint a coach that is already tied to a club.

If Rummenigge is to be believed, this would also rule out moves for Leipzig's Julian Nagelsmann and Liverpool manager Jurgen Klopp.

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."

Jamal Musiala should not change his approach while away with Germany, Hansi Flick insisted after the Bayern Munich teenager was handed his first senior international call-up. 

Having elected to represent Germany ahead of England, whom he played for at youth level, Musiala was selected by Joachim Low for Die Mannschaft's upcoming World Cup qualifiers with Iceland, Romania and North Macedonia. 

Musiala has made 18 Bundesliga appearances in 2020-21 – only four players who are younger than him (18 years, 21 days) have played in more matches across the top five European leagues this term. 

On target in a 4-1 win over Lazio in the Champions League last month, Musiala has demonstrated impressive composure for someone of his tender years. 

And Flick believes displaying the same level-headed attitude will be the key for Musiala in his international career. 

"He should approach it the same way he does things with us, by staying calm. He's an exceptional player," Flick told a media conference ahead of Bayern's Bundesliga clash with Stuttgart. 

Bayern have been pitted against Paris Saint-Germain in the Champions League quarter-finals having eased past Lazio 6-2 on aggregate in the last 16. 

It is a rematch of last year's final, with the reward for winning the tie a semi-final meeting with either Manchester City or Borussia Dortmund.

But the renewal of acquaintances with PSG is not in Flick's immediate focus.

"My focus is on the game against Stuttgart, first and foremost," he said about the draw. "This will be our 18th game in 11 weeks.

"The team has, in this short time, delivered many strong performances once again, including in the most recent games.

"Now comes first Stuttgart, then the important game in Leipzig. We have enough time to prepare for Paris.

"Manchester City is currently one of the most consistent teams in Europe, so it is a challenge for us and Dortmund. We play the Champions League for that. 

"But we and Dortmund have the opportunity to go one round further.

"It's important to play two games at the highest level. Of course, it's a tough opponent, as you saw in the final. But we also have tremendous quality."

A resurgent Leroy Sane has his sights set on achieving his "huge" career goal of experiencing the Champions League glory his Bayern Munich team-mates enjoyed last season.

The winger joined Bayern from Manchester City after they had tasted European success by defeating Paris Saint-Germain in the final.

Sane had a mixed start at Bayern, in and out the line up as he worked his way back from a long-term injury that restricted him to two appearances in his final season at City.

The 25-year-old has looked like his old self of late, registering either a goal or assist in four of his last five matches, including a strike in Bayern's emphatic 4-1 away win in the last-16 first leg away to Lazio.

Bayern were four goals up after 47 minutes of that game, but ahead of Wednesday's home second leg against Lazio, Sane wants his team-mates to take nothing for granted, which would jeopardise his Champions League dream.

"[Winning the Champions League is] a huge goal of mine," said Sane.

"That is why I place so much value on delivering a good match on Wednesday and for the rest of the season.

"When we have Champions League matches, we need to always be well prepared and up for it. 

"All of us know that a lot can still happen. Just because we scored a few goals in the first leg doesn't mean that we are through. 

"Lazio have a strong team and things could backfire if we don't take it seriously.

"I'm feeling better and better, and have had time to get to know the team and how we play. We get along very well off the pitch as well. Everyone is prepared to work hard, which benefits us all.

"At first, you need to get to know the workings of a team. For me it was even harder, because I didn't have a rhythm after a long injury. 

"So I needed to find my own rhythm back at first. Now I feel a lot better and I have got to know the team better. That is one of the reasons why things have gone uphill for me lately."

Bayern are hosting Lazio for the first time in European competition.

None of the last 21 sides facing them away from home for the first time in the European Cup or Champions League have won (W20 D1) since Bordeaux triumphed 2-0 back in November 2009.

Head coach Hansi Flick hopes to have fitness doubts Manuel Neuer and Kingsley Coman available.

"Manu has a slight cold, and Kingsley is dealing with some muscle issues," he said. "We will have to wait and see, but we are hoping that both will be able to feature on Wednesday.

"We want to win this game [the second leg] as well. We're in the midst of a good run and want to continue it.

"Especially since we're at home, we really want to win to further build our self-confidence.

"We've delivered strong performances in the Champions League, as well as in the Bundesliga. Our current aim is to continue on in this manner."

Flick was not keen to discuss the Germany job, which will become vacant when Joachim Low leaves after Euro 2020, any further.

"I have said everything about this topic, but nothing has changed for me," he said. "I do not comment on the topic."

Since Flick took charge of the club, Bayern have won their six home games in the Champions League by an aggregate score of 18-3. 

However, only one of the previous six have come in the knockout stages of the competition – beating Chelsea 4-1 in the second leg of last season’s round of 16.

Lazio, meanwhile, have only won one of their last 15 away games in the Champions League (D5 L9).

The Serie A side are winless in the last eight matches of that run (D4 L4) and have not one away in the competition was back in September 2003.

Cristiano Ronaldo's future is dominating headlines.

After Juventus crashed out of the Champions League last 16, Ronaldo has been linked with a move away from Turin.

Could a return to the Spanish capital be on the cards?

TOP STORY – RONALDO ON MADRID'S RADAR

Real Madrid are interested in bringing Juventus superstar Cristiano Ronaldo back to the club, according to the frontpage of Monday's Diario AS.

Ronaldo – Madrid's all-time leading goalscorer – left Los Blancos for Juventus in 2018 but his future with the Serie A champions is far from certain following their Champions League elimination.

Diario AS says Ronaldo represents an easier and quicker target than Borussia Dortmund's Erling Haaland and Paris Saint-Germain superstar Kylian Mbappe.

Marca, though, insists Ronaldo's possible return does not alter Madrid's objectives as they weigh up either Haaland – heavily linked to Manchester City, Manchester United, Chelsea, Barcelona, Juve, PSG and Liverpool – or Mbappe.

Hansi Flick is the ideal candidate to succeed Joachim Low as Germany's next head coach, according to Lothar Matthaus.

Low announced on Tuesday he will step down from his role with the national team after the Euro 2020 finals, having been in charge for the past 15 years.

Bayern Munich's Flick was installed as one of the early favourites to take over from Low, whom he previously worked alongside as assistant head coach for eight years.

Flick masterminded a magnificent Bundesliga, DFB-Pokal and Champions League treble last season, which Bayern have added to with the Club World Cup, UEFA Super Cup and DFL-Supercup this season.

The 56-year-old appeared to rule himself out of the running earlier this week as he remains under contract at the Allianz Arena until 2023.

But Bayern CEO Karl-Heinz Rummenigge will leave his role at the end of the year and Matthaus has urged the DFB to move for Flick should he become available.

"He's a person of harmony, but he has to feel good," Matthaus told Sky Sport Germany. "If he no longer feels comfortable at Bayern, he will tell his bosses and then he will be the ideal candidate for the national team."

Jurgen Klopp and Julian Nagelsmann, in charge of Liverpool and RB Leipzig respectively, have also distanced themselves from one of the top positions in international football.

Meanwhile, Matthaus previously stated he had no interest in leading the country he represented 150 times as a player, but he has now changed his stance.

"The DFB has to think about what it wants. Pros and cons are weighed up against each candidate," he said.

"I'm someone who likes to help. If I had the feeling that those responsible were united behind the decision, I would start to think about it."

Germany Under-21s coach Stefan Kuntz and former Leipzig boss Ralf Rangnick have also been linked with the position, though the latter is reported to be in talks with Schalke over the possibility of returning to the club as sporting director.

Hansi Flick paid tribute to coaches Toni Tapalovic and Miroslav Klose after Bayern Munich earned a 3-1 win over Werder Bremen on Saturday.

The Bundesliga champions extended their lead at the summit to five points thanks to goals from Leon Goretzka, Serge Gnabry and Robert Lewandowski at Weser Stadium.

The first of those came via a corner routine that saw Thomas Muller's near-post flick-on headed powerfully home by Goretzka.

Speaking after the match, Flick revealed that goalkeeping coach Tapalovic and assistant Klose came up with the set-piece.

He said: "It was a safe and more than deserved victory that could have been bigger. 

"We implemented what we set out to do, to have a good position on the pitch and to put our opponents under pressure. 

"I'm particularly pleased that we took the lead with a corner kick, and Toni Tapalovic and Miro Klose came up with something. That is thanks to them and a compliment to their work."

However, Flick was not impressed with the late concession of a consolation goal, which saw Bayern's high line exposed.

He added: "Of course the goal annoyed me. But our back four and the team in the entire defensive network did very well, we hardly allowed any chances. 

"I am very satisfied with the result, compliments to the team."

Goalscorer Goretzka echoed his manager's sentiments, expressing both delight over the well-worked nature of the opening goal and frustration over Werder marking the scoresheet.

He said: "It was a convincing performance. It's not easy in Bremen because we've struggled [there] over the past few years. 

"The opponent was very deep, so of course a goal like that [the corner] is good. We had a good plan in possession of the ball, so we were able to prevent the counterattack very well, except at 3-1, which annoys us a lot because we wanted to play to zero."

Hansi Flick is not interested in "speculation" he could take over as Germany head coach as he eyes more trophies for Bayern Munich.

Flick is among the names linked with the Germany job after long-serving boss Joachim Low decided to step down after Euro 2020.

Bayern supremo Flick masterminded a magnificent Bundesliga, DFB-Pokal and UEFA Champions League treble last season.

The Bavarian giants have also won the FIFA Club World Cup, UEFA Super Cup and DFL-Supercup in a dream start to Flick's tenure.

Bayern are top of the Bundesliga and remain in the hunt to win the Champions League, so Flick is focused on the job in hand rather than the possibility of succeeding Low.

He said in a press conference on Friday: "I have a contract until 2023 and want to be successful and win titles with Bayern Munich. It's not the time to speculate about my future."

Flick added: "I'm interested in the here and now. I am now looking after my team and the game against Werder Bremen [on Saturday]. As I said, speculation is not an issue for me."

Asked if he was surprised Low will walk away from the job, he said. "Yes, yes. He did a very good job for German football. Can be very proud of what he has achieved."

Full-back Benjamin Pavard is back in the squad for the clash with Bremen at the Weserstadion after being out of action following his positive coronavirus test.

David Alaba missed training on Thursday due to a muscular injury, but will be monitored in a session on Friday.

Bayern have scored 13 goals in their last three games and Flick expects the leaders to show intensity from the start as they go in search of a fourth consecutive victory.

He said: "Bremen have a very good defence, they stay compact and don't give away much space. We found that in the home match. It's important that we are aggressive off the ball and find good solutions with it."

Julian Nagelsmann does not expect Jurgen Klopp to be tempted by the Germany job after Joachim Low announced he would step down after Euro 2020.

The search for Low's successor is underway, and a poll by Germany's Sky Sport News broadcaster on Tuesday showed Liverpool manager Klopp would be a popular pick.

With over 7,000 votes counted, some 54.6 per cent selected Klopp as the right man for the job, with Ralf Rangnick next in line with a 15.4 per cent share.

Klopp's Liverpool are enduring a deep dip in the Premier League after last season's title triumph, and six successive defeats in the competition at Anfield have seen them slip to eighth place.

But Klopp has enjoyed huge success during his Liverpool reign, winning the Champions League in 2018-19 before the Reds ended a 30-year wait for the domestic title.

He was also highly successful during his time with Mainz and Borussia Dortmund, where he twice won the Bundesliga.

Nagelsmann, whose RB Leipzig side face Liverpool in the Champions League on Wednesday, said: "Jurgen Klopp is an outstanding coach. But I think that both Liverpool and Jurgen are extremely satisfied with each other."

At the age of 33, Nagelsmann appears unlikely to fancy a switch from club management into the international game.

He has performed wonders with Leipzig since being appointed in 2019, achieving a Bundesliga win percentage of 58.62, with 34 victories and just seven defeats in 58 league games in charge.

If he sustains his early coaching performance, the Germany job may be one that Nagelsmann looks at in the future.

For now, he is keen to see how Low bows out, hoping a 15-year reign can end on a high note.

"First of all, it's sad news, but he is still in office," Nagelsmann said. "That's the most important thing: that he will continue and be on the touchline for this big tournament.

"He's had an extreme impact in German football and especially on the national team. He's had great success and defined an era with titles, a development and a second rebuild during his spell."

Nagelsmann pointed to Low bringing through different generations to form new Germany sides, and said he was optimistic the latest incarnation can be trophy contenders at the European Championship.

"I am sure of it, because we have a lot of talented players, which is also an achievement of his," Nagelsmann said. "It's thanks to him making difficult decisions during crucial moments.

"He has also been criticised for this but had a great career as the coach of the German national team nonetheless. I hope he will find a glorious end and then I'm keen on finding out where he will leave his footsteps next."

Germany great Lothar Matthaus backed former Schalke and Leipzig boss Rangnick, who is currently without a club, telling Sky Sport News: "He's free. He's someone who can build something."

The next Germany coach will be expected to lead the team at the Qatar 2022 World Cup, although the qualifying process is set to begin on Low's watch, with games against Iceland, Romania and North Macedonia coming up in late March.

Rudi Voller, the former Germany striker who went on to manage the team from 2000 to 2004, is thankful Low is being afforded the chance to go out on his own terms.

Voller said: "Jogi Low's decision deserves respect. He and his teams have given us great football in many tournaments and by winning the title at the 2014 World Cup, achieved great things for German sport.

"Now Jogi has the chance to go to the European Championship this summer and to achieve a wonderful conclusion. We will all keep our fingers crossed for him."

The search is on for a successor to Joachim Low after Germany's long-serving national team boss announced he would step down after Euro 2020.

Low will complete a 15-year tour of duty as head coach when he leads Die Mannschaft into this year's tournament, delayed a year by the COVID-19 crisis.

His contract had been due to run until after Germany's Qatar 2022 World Cup campaign, but 61-year-old Low has decided the time will be right to step aside before then.

That means the Germany Football Association (DFB) must spring into action and find the right coach to take over from Low, a World Cup winner in 2014.

DFB president Fritz Keller said: "The fact that he informed us about his decision at an early stage is very decent. He gives the DFB consequently the necessary time, calm and a sense of proportion to name his successor."

Germany is enjoying a golden era of producing world-class coaches, and here are five the DFB may consider.

Hansi Flick: Brilliant as Bayern boss, and Low's former right-hand man

Bayern have flourished under Flick's leadership over the past 18 months, having promoted him to the top job when Niko Kovac struggled to get the best from a talented group.

Club CEO Karl-Heinz Rummenigge has noisily shot down the prospect of Flick leaving to become Germany boss, saying the coach will remain at Bayern for next season.

However, Rummenigge himself will step down from his position at Bayern at the turn of the year as Oliver Kahn replaces him, and Flick may see the Germany job as offering greater long-term security.

He served as assistant to Low from 2006 to 2014 so knows the job as well as any contender.

Jurgen Klopp: Could Liverpool adventure be coming to an end?

Liverpool's steep decline in 2021 has led to the first rumblings about Klopp's Anfield future among supporters of the club.

At board level, there has been no indication Liverpool would be happy to lose the man who has led them to Champions League and Premier League title success.

It seems the former Mainz and Borussia Dortmund boss has enough goodwill in the bank to be trusted to turn around the team's fortunes, so if Klopp is to be a contender for the Germany job it would be on him to make a major career decision.

At the age of 53, could he take the methods that have served him so well in the club game onto the international stage?

Stefan Kuntz: Ready to step up?

As coach of the Germany Under-21 team, former national team midfielder Kuntz is already working in the DFB system.

To appoint him would seem an easy option, which is not to suggest it would be the wrong option.

Kuntz's young Germany team won the UEFA Under-21 Championship in 2017 and were runners-up two years later, with the likes of Thilo Kehrer, Luca Waldschmidt and Serge Gnabry all enjoying early international experience under his leadership.

Kuntz is highly regarded as a coach by his fellow Euro 96 winner Oliver Bierhoff, who is Germany's national team director, and that could be a significant factor.

Julian Nagelsmann: Too much, too young?

Nagelsmann, who does not turn 34 until July, seems a long shot for this job.

He has greatly impressed as head coach of Hoffenheim and RB Leipzig and his next calling point is likely to be a bigger club job, perhaps in Spain or England.

Nagelsmann distanced himself from the Germany job within minutes of Low's departure being announced, so it would take a change of heart for him to come into the equation.

If the DFB makes a determined play for him, however, Nagelsmann would have to decide whether he could refuse to serve his country.

Ralf Rangnick: Tactical master could be perfect pick

Veteran Rangnick looked set to join Milan last year, until the surprise element of Stefano Pioli turning the Rossoneri into a winning machine knocked that on the head.

The 62-year-old has been cited as a major influence on the generation that followed him into coaching, with Stuttgart, Hoffenheim, Schalke and Leipzig among the teams he has led.

His tactics typically lean on a high-intensity pressing game, with swift counter-attacking, and Rangnick would surely relish the prospect of leading Germany into a World Cup.

Whether being out of coaching for two seasons might be a hindrance would be a matter for the DFB, with Rangnick currently employed by Red Bull's sporting division.

Thomas Muller has declared himself ready to return to international duty after Germany boss Joachim Low hinted at a recall for the Bayern Munich attacker ahead of Euro 2020.

Low said last week he is considering a U-turn that would see Muller, Mats Hummels and Jerome Boateng return from the wilderness in time for the rescheduled tournament.

The World Cup-winning trio were told by Low in March 2019 that they would no longer be part of his plans, which left Muller – a regular up until that point – "dumbfounded".

However, with Low under pressure on the back of November's 6-0 thrashing against Spain, the long-serving coach has reiterated the door is once again open for the trio.

Speaking to Sky Sport Germany on Saturday, Low said: "The European Championship is a separate competition and our job is to bring the best players and the best team with us in order to guarantee the greatest possible success."

The three players have a combined 246 caps and have impressed at club level since last featuring for Germany, with Muller and Boateng helping Bayern to six major trophies since the start of last season.

Muller, who has a combined 50 goals and assists in the Bundesliga since the start of last season – only team-mate Robert Lewandowski (75) has more – would welcome the chance to represent his country again this year.

"I feel comfortable in the team. Standing on the pitch with the boys is fun, and there are a lot of national team players on the pitch," he said.

"I feel like chasing titles in the summer. We will see if it is the end for me after the Champions League final or whether I will play for the national team. I'm definitely ready."

Muller played 91 minutes of Bayern's 4-2 win over Borussia Dortmund in Saturday's Der Klassiker, a game in which Boateng was forced off in the second half with a knee injury.

Boateng has had numerous setbacks in the past and Bayern boss Hansi Flick is awaiting news on the severity of this latest injury.

"We don't know exactly what he has done," Flick said. "He said he thought he twisted his knee a bit, but we have to wait for the diagnosis. He is having a scan."

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."

Hansi Flick hailed Leon Goretzka's "excellent" three-assist display against Cologne but admitted he was not entirely pleased with Bayern Munich's overall performance in Saturday's 5-1 win.

Bayern put an end to their two-game winless streak in the Bundesliga with a routine victory against their relegation-battling opponents at Allianz Arena to retain a two-point lead on RB Leipzig at the summit.

Goretzka set up goals for Eric Maxim Choupo-Moting, Robert Lewandowski and Serge Gnabry, making it four assists in his last two outings after also teeing up Jamal Musiala's goal in the 4-1 Champions League win at Lazio in midweek. 

The Germany international was singled out for praise by Flick after the win against Cologne, but the Bayern boss acknowledged there is still room for improvement from his side after conceding for the fourth game in a row thanks to Ellyes Skhiri's strike.

"Leon did an excellent job in assisting the goals. That's why he was Man of the Match for me today," Flick said. "We will analyse the game and show it to the team. There were one or two things I didn't like. 

"But we'll go from game to game. That approach worked well last year. What comes out in the end is up to us. If we put in the performances and pick up wins, we can finish top of the league."

Gnabry marked his return from a thigh injury lay-off by scoring twice from his 14 touches of the ball as a second-half substitute, adding to Lewandowski's brace and Choupo-Moting's opener.

Thomas Muller also appeared for the first time since being struck down by coronavirus at the Club World Cup earlier this month and Flick is delighted to have both players fit and available.

"Serge and Thomas were very important to us as substitutes today," he said. "Thomas assisted Lewy [Lewandowski] with his first touch of the game and brought some certainty to our game, which we needed at that point. 

"Serge has scored two goals. Both will be valuable for us in the next games and I'm happy they're back. It's important to be satisfied with the 5-1 scoreline. We deserved the victory even by that margin."

Bayern let Cologne into the game early in the second half before pulling clear with three goals in the final 25 minutes in what was the 100th competitive meeting between the sides.

With his double on Saturday, Gnabry has now scored nine Bundesliga goals against Cologne - more than against any other side in his career - but the attacker agreed with Flick's assessment that Bayern are not quite at 100 per cent.

"When Thomas and I came on, it was a bit tricky for us," he said. "We hadn't been very sharp or dominant. We tried to lift the tempo and immediately made it 3-1. Then it became easier. 

"In the future, we have to make sure we don't have these shaky phases in the game and we come out of the blocks quicker. Of course, opponents will always have a chance, but we have to reduce these spells, then we'll be stronger again."

Bayern Munich returned to winning ways in the Bundesliga as Robert Lewandowski and Serge Gnabry both scored twice in a convincing 5-1 win over Cologne.

After returning to domestic duties following their Club World Cup success in Qatar with a home draw against Arminia Bielefeld, the reigning champions slipped to a 2-1 loss away at Eintracht Frankfurt last weekend.

However, a 4-1 thrashing of Lazio in Champions League action in midweek proved the catalyst for a first league triumph at their Allianz Arena home since January 30.

Lewandowski's first goal helped Bayern ease into a 2-0 half-time lead and while Cologne briefly threatened a comeback, the returning Thomas Muller made an immediate impression off the bench, providing the assist that allowed the competition's leading scorer to take his tally for the campaign to 28.

Like Muller, substitute Gnabry had an impact on his comeback, the Germany international tucking away a pair of routine finishes as the hosts eased clear in the closing stages.

Eric Maxim Choupo-Moting had opened the scoring with his first league goal for the club, heading in an inviting cross from Leon Goretzka, who then went on to set up his side's second before the break.

The midfielder waltzed his way beyond Rafael Czichos before laying the ball off as goalkeeper Timo Horn came towards him, allowing the ever-ready Lewandowski to roll it into the net.

Cologne failed to even muster an attempt as the first half proved to be one-way traffic, yet they were gifted a route back into the game when hesitation between centre-back pairing Jerome Boateng and David Alaba allowed Ellyes Skhiri in to produce a delicate lofted finish over the advancing Manuel Neuer.

The goal caused a brief wobble, yet the 64th-minute arrival of Muller - back after overcoming coronavirus - helped steady Bayern, the substitute teeing up Lewandowski to restore the two-goal cushion with a shot on the turn.

Dominick Drexler hit the post from a tight angle after robbing possession from Neuer before Gnabry's four-minute brace, the second of which was set up by the outstanding Goretzka with another delightful delivery into the area, added a touch of gloss to the final scoreline.

What does it mean? Bayern remain clear at the summit

Bayern's recent blip had allowed the chasing pack – led by RB Leipzig – to close the gap at the top of the table. Flick's side have already lost more Bundesliga games in 2021 (two) than they did across the entirety of the previous year.

This win is therefore most welcome in what has suddenly become a tighter-than-expected title race, but Flick – who made 44 appearances for Cologne during his playing career - will be concerned at the careless defensive lapse that allowed Skhiri to give the visitors a slither of hope.

Duo back to boost Bayern

While COVID-19 had kept Muller away, Gnabry had not featured since the Club World Cup final due to a thigh issue. The latter only had 13 touches during his goalscoring cameo, but the availability of the pair helps add further strength in depth, even if the fixture congestion eases in March.

Defensive cracks raise concerns

Bayern had conceded 31 goals prior to this game, their highest tally through 22 league games in a campaign since 1991-92. The chance of a clean sheet disappeared when Boateng and Alaba dithered over who was going to attack a loose ball on the edge of the penalty area, in the end neither bothering to take control of the situation.

What's next?

Bayern have a rare week between fixtures, giving them time to prepare for the visit of Borussia Dortmund next Saturday. Cologne, meanwhile, will be hosting Werder Bremen the following day.
