Hertha has a greater chance of winning. they played well at home. even against Dortmund, they can win. although it was destroyed by Cologne 1-3 in the match against Bochum, I think Hertha can handle it.
both teams do not have consistent performance. as you said both are problematic in midfield. and I think they also have problems in finishing.
I am not a friend of placing a bet for an draw and i will take the risk and will make one for a win for Bochum against Hertha Berlin with 2 : 1 .
But when i look back the last weeks its always comes diffrent and maybe they playing the draw , hopefully not.
More important are the tomorrow games and the one on sunday from Munich and Dortmund.
