Mainz is now on 11th place and they aren't satisfy with that postion, so I expect them to attack in this game. They are really involved in last period in some high -scoring games, they played twice in a row with more than 3 goals. Last week they played 3-2 against Freibourg.
Schalke is now looking to get promotion and to play in European comptitions for next season. Schalke have great attakcing options, they have Huntelar, Rarfan, Meyer and others great strikers, so I expect them to score several goals here.
