I think it will only be an absolute win for Bayern because it was possible for Leipzig last season to be quite good but for this season they are very difficult to develop and indeed I feel they will have no hope against Bayern at this time.
Bayern's advantage is very complex now that apart from they are playing at home, their condition is also quite good and this is the opposite of leipzig.
Even though their current performance is quite good, especially in the last 3 matches, I do feel that Leipzig will definitely find it difficult in this match.
