I have always said this about Dortmund. They can never be relied on. Even before their draw to Bochum, I always knew they will slip up and let Bayern take the lead. All Bayern needs to do now is win all their remaining matches and they have won the league.
You said Bayern have been inconsistent in the league this season and that's true, but still Dortmund could not make use of the opportunity. I have been saying this all season long. I am rooting for them but I just find it hard to trust them. They were in a position that all they had to do was win five matches and the league is theirs but they are about to bottle it. Now they will just have to hope Bayern slips up.
it really doesn't make sense with the final result of the match between dortmund vs bochum, many opportunities for dortmund were created but all of them failed to become goals, even bochum scored first in the 5th minute'. Soon Bayern will face Hertha and Bayern's chances of winning are very big, it will be very embarrassing for Tuchel if he can't give Bayern a win in today's match.
