Actually, I do not expect anything other than a 3-point for Leverkusen.
First of all, Leverkusen cannot afford to lose any match right now because that will give Bayern Munich a lifeline.
Secondly, Leverkusen cannot afford to lose easy matches like this, right?

Bayer 04 Leverkusen-----Draw-----1.FSV Mainz 05
            1.32                      6                9.40

You know this is literally the first game of the table going up against a team in the relegation zone.
If somehow Mainz can even get 1 point from this match I am going to be pretty impressed.
Or it will have to be a pretty trash performance from Leverkusen.

If you want to place 1x2 bet, don't miss this opportunity.
