Mainz v Nurnberg
Mainz is 2nd, but 7 points behind Borussia Dortmund and 2 before Bayer Leverkusen. Mainz started the season great, but they got 4 consecutive losses and their form dropped. In the last round they won against Borussia M'gladbach 2:3.
Nurnberg is 10th with 18 points. Nurnberg had some good matches, but in the latest they do not perform well. Losses to Beyern Munich 0:3 and Kaiserslautern 1:3 show that they are in bad form.
Mainz has 5 wins at home against this opponent and only 1 loss. Although they are not in good form I expect they pickup a good win.
Prediction: Mainz win
Bookmaker: Paddy Power
Odds: 1.91
