For the fact that the match between Bayern Munich and Schalke will be taking place in the home of Bayern Munich, I don't think Schalke will succed in winning the game against Bayern Munich. This a chance for Bayern Munich to make full point out from this game to make sure they win Bundesliga league.
I guess we will not see on this game that Bayern Munich will be getting already there the Title as they are only 1 point in front of Dortmund.
And they havnt won this game for now , for sure on the paper and from the players they have , they should win that game against Schalke.
Schalke is always good for making it hard to play against them and they need the points as well.
