Bayern Munich are not top of the Bundesliga for first time in 14 months, new leaders RB Leipzig made history and Pierre-Emerick Aubameyang dedicates his goal to a French rapper.

Here are five things we learned from the eleventh round of matches in the Bundesliga:

Unbeaten RB Leipzig have usurped Bayern from the top of the league table and Borussia Dortmund coach Thomas Tuchel thinks the new leaders can be the Leicester City of Germany.

Last season, Leicester were the shock winners of the English Premier League and Tuchel says record-breaking Leipzig can do the same in Germany.

"Last year we had the phenomenon of Leicester City in England. Leipzig can go on exactly the same path," said Tuchel.

"I'm convinced of that when I see them."

Leipzig set a new record of 11 games unbeaten for a club at the start of their first Bundesliga season with a 3-2 win at Bayer Leverkusen on Friday.

The result left them three points clear of second-placed Bayern, who lost 1-0 at Tuchel's Dortmund on Saturday.

"It's nice for the league, it's what everyone wanted -- but not us," snapped Bayern's captain Philipp Lahm after Bayern's 1-0 defeat at Dortmund in Germany's 'Der Klassiker'.

Aubameyang's goal settled a bad-tempered clash as Dortmund claimed their first home league win over Bayern since 2012.

Bayern are finally spluttering having won a record four consecutive German league titles since 2012/13.

For the first time since September 2015, Bayern are off top spot as new coach Carlo Ancelotti tasted defeat for the first time in 11 German league games.

To compare, his predecessor Pep Guardiola lost his first league games on his 29th match during his debut Bundesliga season in 2013/14.

"Bayern are missing the fitness, the joy and the authority in their play," observed Sky expert and ex-Germany captain Lothar Matthaeus.

"A lot of things which made them strong last season are missing now."

Aubameyang has celebrated scoring Dortmund goals with somersaults and by donning a Batman outfit in the past, but he dropped to the turf for three push-ups after scoring the winning goal against Bayern.

"It was for my mate Gradur. He's a famous rapper from France, who was in the stadium," explained Aubameyang as the artist has performed push-ups in his music videos.

Gradur -- full name Wanani Gradi Mariadi -- is a star in France where his debut album 'L'homme au bob' went to Number One.

Leipzig is roughly 300kms from the coast, but RB's head coach Ralph Hasenhuettl is comparing the new Bundesliga leaders to icebergs -- the real danger is their potential lying under the surface.

Only around ten percent of an iceberg is above the waterline and Hasenhuettl used the image in a motivation video before Friday's 3-2 win at Leverkusen to inspire his side to sink their opponents.

"We tried to show the team their true potential is like an iceberg before the match," said the Austrian, whose side is unbeaten in their first 11 Bundesliga games -- a record for a newly-promoted team.

"Much of the potential that we have is not yet on display.

"We had an incredibly good attitude and we're hard to beat," he added with Leipzig to play second-placed Bayern in Munich on December 20.

Guardiola's Manchester City are Borussia Moenchengladbach's next opponents on Wednesday with Andre Schubert's 'Foals' dropping fast down the league table.

Gladbach's 2-1 defeat at home to Cologne on Saturday left them 11th and winless in their last six league games dating to the end of September.

The Champions League home match against City is a daunting prospect given Manchester's 3-1 home win over Barcelona three weeks ago and head coach Schubert is under pressure.

"Now comes the question about the coach," Gladbach's director of sport Max Eberl fumed to Sky after the Cologne defeat before even asked about Schubert.

"For me, that's absurd. Today a team lost who had deserved to win."

A heavy defeat to City will do little for Schubert's future with Hoffenheim, Dortmund and Barcelona, away, their forthcoming opponents.
