I think that Dortmund will have a tougher game than Bayern Munich next week. Because their opponent is Leverkusen which is a tough one than Leipzig this season. Leverkusen are at the third position in the standings right now. However, this still doesn't matter too much for Dortmund if we take their recent effort into account. For example, Freiburg were also one of the top teams in the standings but Dortmund still didn't care about it and destroyed them. Maybe the Leverkusen game would be a competitive one but Dortmund should be winning this one too.
