With just two Bundesliga games remaining this season, neither of these sides have much to gain, making this a bit of a deadwood fixture. This is a match where both teams can afford to play with some freedom without the usual pressure of the league standings. Mainz are seven points adrift of the European spots with no chance of closing the gap on Freiburg, while Union Berlin sit seven points above the relegation zone.
BTTS has landed in each of Mainz's last three matches, a run which includes an entertaining 4-3 defeat against Bayern Munich, which shows how they are more than capable going forward. Union Berlin have been even more consistent when it comes to goals, with BTTS landing in each of their last five consecutive matches, during which they have produced an average of 3.4 goals per game.
