Bayern reclaim top spot as Musiala and Mane shine

"It is a lot of fun to watch them. [We are] a great mix of quality and configuration," Nagelsmann said. 

"Huge compliments [to the team]. It's unbelievable at the moment."

Sublime performances from forwards Jamal Musiala and Sadio Mane pushed Bayern two points clear at the top of the table, the first time they have led the Bundesliga since August. 

Serge Gnabry opened the scoring after just six minutes thanks to an assist from Mane, while teenager Musiala scored his seventh league goal of the season in the 28th minute.

Mainz centre-back Alexander Hack fouled Mane in the box in the 40th minute. The former Liverpool striker took the penalty and while 'keeper Robin Zentner saved his shot, the Senegalese pounced on the rebound to put Bayern 3-0 ahead.

Mainz, who missed a 45th minute penalty, had another brief glimmer of hope before the half-time break when Silvan Widmer headed in from a corner, but Bayern midfielder Leon Goretzka scored from a Mane cross in the 58th minute to give Bayern an unassailable 4-1 lead.

French striker Mathys Tel, 17, and Eric Maxim Choupo-Moting added goals for Bayern late on, while Mainz's Marcus Ingvartsen pounced on a mistake from Munich goalkeeper Sven Ulreich to leave the final score at 6-2. 

Mainz manager Bo Svensson congratulated Nagelsmann and Bayern "on a well-deserved victory", but was deeply unhappy with his own side. "We missed everything. I didn't like what I saw in the second half."

Bayern have now won six games in a row, scoring 25 goals since their last-minute 2-2 draw away at Dortmund in early October. 

Leipzig stay in contention

Elsewhere, RB Leipzig lifted themselves up to within touching distance of the top four with a 2-0 win at home against Bayer Leverkusen thanks to goals from Christopher Nkunku and Timo Werner. 

Leverkusen have now won just one in six since former Real Madrid, Bayern Munich and Liverpool midfielder Xabi Alonso took over as manager. 

Wolfsburg thrashed a hapless Bochum 4-0 at home, in the Wolves' most dominant performance since being taken over by former Bayern manager Niko Kovac in the summer.

In Saturday afternoon's other match, Stuttgart lifted themselves out of the bottom three with a 2-1 victory against Augsburg, thanks to an injury time winner from Waldemar Anton.

The win was Stuttgart's third in four games since firing American manager Pellegrino Matarazzo.

In Saturday's late game, Dortmund travel to Eintracht Frankfurt.
