Bayern Munich still have quite a big chance in the second leg, and it is still very possible for them to overcome the long journey in the Champions League this season.
In the champions league they are still one of the favorites even though their position has decreased, in the group phase the bookies put Bayern Munich as the second favorite to become champions but after entering the round of 16 they dropped to only fourth place and are not even more favorites than Arsenal
So performances in other competitions will also influence the assessment of Bayern Munich, but after entering the quarter-finals the assessment will be different again and I am still quite confident that Bayern will go to the quarter-finals because Lazio is only one goal ahead of Bayern and it shouldn't be a difficult thing for Bayern to catch to achieved victory by more than two goals
