Werder gave themselves a chance with that win against Schalke, Mainz losing at home also helped.
They have 1 game in hand, I did not give them any chances 5 days ago but things change quickly in football.
Both teams still have a couple of tough fixtures to play before the end of the season, Werder Bremen would be hoping Bayern would have sealed the league title before they have to face them on the 16th of June, Mainz would be hoping to get similar luck as they face Dortmund the following day.
For today's fixtures, I expect a win for Dortmund, with O 2.5 goals, I'm not so confident about Mönchengladbach, I'll add it to the parley as both teams can score, O 2.5 goals.
