Inconsistency in Bayern Munich recent performances has been noticeable as seen by their losses and particularly their loss to Leipzig. In contrast Dortmund has been playing admirably winning four of their last five games while drawing the other. This winning streak augurs well for Dortmund as they take on Mainz a team that may not present as much of a challenge. But it is crucial to remember that Bayern Munich final game of the year is against Koln. It would be naive to presume that Munich would falter against Koln despite their inconsistent results. It will be interesting to watch how the Bundesliga season plays out to see if Dortmund can take this chance and possibly weaken Munich grip on the league.
