Rafinha returns to the starting line-up, after being suspended in the Bundesliga last weekend.
Daniel van Buyten and Diego Contento are still injured, meaning Jerome Boateng will start at centre-back again, with Anatoliy Tymoshchuk switching back to midfield.
Arjen Robben and his wife await their third baby, meaning Thomas Müller could replace the Dutchman on the right wing, with Toni Kroos switching to the central position behind Mario Gomez.
Stuttgart have not been in their best form in the Bundesliga lately, but a cup game against Bayern is a massive opportunity to turn things around again. The team will be highly motivated to take their chances.
Bayern's start to the second half of the Bundesliga season has not been great and the team seems to lack a plan B, if opponents defend deep against them and then hit them on the break. Anatoliy Tymoshchuk and Toni Kroos switching back to their natural positions should give the team more stability again though.
Expect Stuttgart to defend deep with two banks of four. Bayern will dominate possession, but they have to create more chances again.
