If you look at the standings of the teams, then Bayern's path is a little, but easier - because they play literally with the two worst teams in the Bundesliga. Mainz is easier for Dortmund than Leipzig is for Bayern, but this is probably the only pair of the 5 remaining where Bayern are in a slightly worse position - the rest are either equal or in favor of Bayern. In any case, bookmakers consider Bayern as the clear favorite:
Bundesliga - Winner
Bayern Munich 1.55
Borussia Dortmund 2.25
I'm really not surprised at these odds. I think Borussia Dortmund are not a good enough team to win the Bundesliga. Bayern Munich are bad this season, but Borussia
Dortmund are in a worse situation than them. They too are close to experiencing Arsenal's disappointment. Actually, their match fixtures look comfortable, but it doesn't look to me like they can win all of their remaining matches. I think they will make more mistakes than Bayern Munich. They have an advantage at the moment, but I think they will not be able to maintain this until the end of the season.
Now Dortmund are in a better position and everything depends on them - Bayern don't even have a face-to-face meeting anymore to fix something. I think that at a distance of 5 games (which is a fairly short distance) Dortmund have a significant advantage. Bayern's chances are only that because people, based on Bayern's historical dominance and Dortmund's "clown" habits, expect Dortmund to make a mistake, but this may not happen.
