Semi-finals in the CL minimum, in my opionion!
Bayern are on a high right now and I think they are maybe peaking too early. They are a still a class of their own in Bundesliga; not necessarily, when you are looking at a single game, but when you look at the big picture. They have some unbelievable consistency year in, year out and very rarely are on a bad run for more than like three games. And even when they are struggling a bit, they are able to beat all the scrub teams in Bundesliga. And that is something that teams like Dortmund, Leipzig and Leverkusen are missing. These teams will always have stretches during a season, where they can't get anything going and Bayern will just run away point-wise. Leipzig might get there in the next years, but Dortmund and Leverkusen are trying for years and are not able to get closer to Bayern in terms of consistency.
In CL things are different - there, Bayern is the Dortmund/Leipzig/Leverkusen. In the last years, they were missing that little extra to go very deep and I am not sure, if this year will be different (having in mind they are probably peaking right now).
Lewandowski is out for 4 weeks now and that is something Bayern should be very worried about. They were very lucky these last years, with Lewandowski being healthy all the time, since they never had a backup for him - it was a risky game they played. Now there is some big void upfront and teams will have an easier time defending, since they don't have to put three players on Lewandowski now.
