bundesliga.com looks at how both sides are shaping up ahead of Matchday 19's standout encounter in the Bavarian capital...
A number of Bayern players referred to last Friday's humbling at the Volkswagen Arena as 'a wake-up call'. The league leaders conceded as many goals in one night as they had over the course of the entire Hinrunde, but certainly have no reason to panic. They're still eight points clear of the Wolves and 15 ahead of fourth-placed Schalke.
Dante and both had a tough time of it in Wolfsburg and may be rested. Medhi Benatia and (r.) could come in, but Rafinha, Franck Ribery, , Thiago Alcantara and Javi Martinez are all out. Holger Badstuber is also an option at the back following injury.
misses out after being sent off against Hannover. (l.) would appear to be the most likely candidate to come into the side in the Dutchman's stead, with Roberto Di Matteo not exactly blessed when it comes to like-for-like replacements in attack.
(r.) didn't have too much to feed off on Matchday 18, but he's unlikely to go hungry for much longer. Even though the Polish international hasn't scored since the 4-0 win over FC Augsburg on 13 December - assuming the service is there - he should have plenty of joy against Schalke's experimental three-man defence.
By the same token, (l.) will be looking to exploit any apparent weaknesses in the Bayern ranks following the champions' monumental collapse in Wolfsburg. Only Alex Meier and Arjen Robben have scored more league goals in 2014/15 than the Cameroonian international, who has struck four times in his last two outings on the road.
Pep Guardiola (FC Bayern coach): "If we give them the chance to counter, we'll be in trouble."
Roberto Di Matteo (Schalke 04 coach): "We started well on Saturday and a win always gives you self-confidence for the tasks ahead."
Prior to Friday's defeat, Bayern hadn't lost a league game since going down 3-0 at home to Borussia Dortmund on 12 April 2014. Schalke, meanwhile, are unbeaten in their last three domestically and have won their last two away from the Veltins Arena.
World Cup winner (l.) helped Schalke put an end to a run of seven successive league defeats against Bayern with the equalising goal on Matchday 2. The Royal Blues have, however, only won once in Munich in the last decade, losing six and drawing two.
