The game between Hertha Berlin and Bayern Munich is very important for Dortmund because they lose two points this week and if Bayern Munich gets the full three points from this game they can take back their position in the first place of the table but since Bayern Munich had an unstable situation lately I won't be surprised if they lose points in this game against Hertha Berlin.
Regardless, I'm still pretty sure Bayern will win this match.
Hertha's current condition is so bad that they are even stranded at the bottom of the table which makes it easier for Bayern. Of course even if they are not really good enough this season but the bundesliga trophy which has been there since 10 seasons must be saved to make face they are still there.
