The defending champions started the campaign in outstanding fashion when they destroyed Schalke 8-0, in what was a message to the rest of the league that they will once again be a formidable force in 2020/21.
However, they followed that up with one of the shocks of the season already as they were taken apart in a 4-1 loss versus Hoffenheim.
This weekend, they take on an Arminia side who have won one, drawn one, and lost one so far.
The Bavarians will be without Leroy Sane for the trip as he recovers from a knee injury which kept him out of the Germany squad for the international break.
They have been boosted by the return of Kingsley Coman, though.
Bayern actually played in a match on Thursday evening as they comfortably progressed in the DFB-Pokal against FC Duren, but a number of first team players, including those on international duty, were rested.
