This game was expected for Dortmund to win but they still lose to Bochum. The way Dortmund is going it seems if Bayern Munich comes back to their normal performance they will easily take the first position from Dortmund. Dortmund is not very okay this season to win the league.
Tomorrow's Bayern Munich match will be decisive, if Thomas Tuchel's team manages to win then it is certain that Bayern will return to the top of the standings because currently Bayern is only two points adrift of Dortmund.
Bayern Munich has a more than 75% chance of winning, I didn't expect them will make a mistake like a few weeks ago when they draw against Hoffenheim
