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.
Schalke 04 are destined for the relegation. They look hopeless. Looking at the number of goals they've been conceding one may suggest that another trouncing is loading. I'm expecting the visitors to ship another 3+ goals.
