But also Leverkusen is currently not in their best form, 6 points from the last 5 matchdays and not to forget the embarrassing defeat against RW Essen in the cup.
Mainz, however, is currently showing a positive trend if you look at the results of the last few match days.
In addition, some key players are not in the squad for the upcoming game at Leverkusen, which is certainly an important point:
Actually, a game with a clear outcome but in relation to the above points, it can end differently ;-)
As regards to Bayern, they are in a good condition and they are the closest team to be able to make it to the championship. 
Dortmund still seem a little more unreliable comparing to Leverkusen. For the Leverkusen-Mainz game, we must be ready for surprises I think. Although there is a huge gap between these teams, Mainz have nothing to lose and started playing better. But I'd like to see Leverkusen winning this match.
