Defending champions Bayern have already qualified for the knockout stages and need to better Manchester City's result against Viktoria Plzen on Wednesday to make sure of finishing top of Group D.
President Uli Hoeness told the Bayern website prior to the team's departure for Russia: "(I'd like) at least a point, even better a win.
"Then the starting point for the final game against Manchester City is excellent. We really want to be group winners."
