- Klassiker defeat was Bayern's first in the Bundesliga this season.
- Champions three points behind promoted Leipzig, who beat Leverkusen last time out.
- Bayer lost 3-0 on their last visit to the Allianz Arena.
FC Bayern München will be determined to put their Klassiker defeat firmly behind them and set about closing the gap on leaders RB Leipzig as they host Bayer 04 Leverkusen in a highly-anticipated clash on Saturday (kick-off 18:30CET/17:30GMT).
For the first time since September 2015, Bayern have spent a week off the top of the Bundesliga. After drawing with TSG 1899 Hoffenheim and losing to Borussia Dortmund, the Bavarian giants have slipped three points behind surprise leaders Leipzig, and will be determined to right a few wrongs when Leverkusen come to town. Coach Carlo Ancelotti will be hoping that Robert Lewandowski adds to his seven-goal tally, and that Thomas Müller – who has netted three goals in previous meetings with Bayer – can finally get off the mark this season.
Leverkusen coach Roger Schmidt will not be too impressed with how his team twice threw away the lead in their loss to Leipzig last time out. However, they sealed a place in the UEFA Champions League Round of 16 in midweek, and will be looking to build on that as they try to inflict a second straight Bundesliga defeat on Bayern. Schmidt's not-so-secret weapon could well be Javier 'Chicharito' Hernandez, who hasn't scored since Matchday 6, but will be determined to open his Bundesliga account against the record champions.
- Bayern head into this match below top spot in the Bundesliga for the first time in 14 months.
- The last time Bayern went into a match off the top (on Matchday 6 last season), they came away 5-1 winners at home to Wolfsburg - the night when Lewandowski famously scored five goals in nine minutes off the bench.
- Leverkusen have lost five games so far this season. They haven't lost so many this early since the 1982/83 campaign.
- Bayern have the second-oldest squad in the Bundesliga; Leverkusen have the second-youngest.
- Manuel Neuer has had trouble with Leverkusen throughout his career. He has lost to Bayer nine times, more than any other club.
- Since joining Bayern in 2014, Lewandowski has yet to score against Leverkusen.
- Last season, Lewandowski and Müller had combined for 23 goals after 11 games. This season, the Poland international has scored seven; his German counterpart none.
