This is an interesting one. Neither Koln nor Borussia are showing any consistency in results.
The hosts are in the middle of the relegation battle and need points. Dortmund look vulnerable and even though they are clear favourites in this one, I won't risk putting money on their win. I predict both teams to score here.
It looks like Schalke have accepted the fact that they'll be competing in the 2nd division next season. Therefore, I think the visiting team won't score at BayArena - something they did in their last three games acorss all competitions.
