Paderborn against Schalke, for example. Or Regensburg against Nürnberg. Although this game could already be a top game, as the first one plays against the fifth and Nürnberg could reach 12 points too.
If you will, Regensburg vs Nuremberg is not only a Bavarian derby but also the actual top match this weekend. It will be interesting to see if Regensburg can continue their winning streak after their first loss in their last game, or if their four wins in their first four games were just an exception.
Paderborn vs. Schalke match will certainly be interesting as well. Paderborn is currently second and has had a very good start to the season. If they manage to win against Schalke, the little eurphoria at Schalke after the first win in the last match will quickly be gone again.
