Just when it seemed RB Leipzig might be the team to inflict Bayern Munich 's first Bundesliga loss this season, Bayern found an extra gear.

Bayern scored five goals in 38 second-half minutes to rout Leipzig 5-1 after going into halftime behind for the first time in the league this season.

Harry Kane scored his 21st Bundesliga goal of what could yet be a record-breaking season, but it was a team effort with five different scorers. Goalkeeper Manuel Neuer, too, stepped up with crucial saves as speculation ramps up over whether Bayern will extend the 39-year-old's contract.

Jürgen Klopp, watching on in his capacity as Red Bull's head of global soccer, was pleased when Rômulo turned in David Raum's cross to take the lead in a dominant though wasteful first half performance.

Leipzig blunders got Bayern back into the game. In the 50th minute, Dayot Upamecano caught Leipzig's Christoph Baumgartner in possession and played in Serge Gnabry to score, and in the 67th Ridle Baku slipped as he went to intercept a cross leaving Kane with an easy finish.

The England striker's goal broke a tie with Manchester City's Erling Haaland as the leading scorer in Europe's top five leagues this season.

After that it was one-way traffic as Jonathan Tah, Aleksandar Pavlovic and Michael Olise scored in the 83rd, 85th and 88th minutes to complete Bayern's victory. It was Olise's 100th goal in all competitions for Bayern.

To cap it off, attacking midfielder Jamal Musiala came off the bench late on for his first game since July when he broke his left leg at the Club World Cup, and celebrated with the Bayern fans after the final whistle.
