Ahead of the clash with the already safe Mainz, the Dutchman declared: "We don't need to think about what's happening on the pitch at Gladbach. We have to win our game. And then we'll see if that's enough in the end."
In the best-case scenario, the Werkself will be happy to repeat the drama of the final matchday of the 2018/19 league campaign: Back then, the Black and Reds qualified for the Champions League with an emphatic 5-1 win against Hertha Berlin and a 2-0 defeat for Gladbach against Borussia Dortmund. "We showed then what is possible," said Bosz.
Good news: Ahead of the game with Mainz, the 56-year-old coach can select his team from his whole squad with the exception of Aleksandar Dragovic who is currently serving a one-match ban. Karim Bellarabi and captain Lars Bender returned to training with the team on Friday following injury. Bosz explained: "We'll see who plays tomorrow. Our only interest is definitely winning the match."
The team coached by Achim Beierlorzer have already secured their top-flight status with two recent wins at Dortmund (2-0) and fellow relegation candidates Werder Bremen (3-1). Bosz does not believe Mainz will let the season end with a whimper. The Werkself coach commenting on tomorrow's opponents: "They played very well against us in our narrow win earlier in the season (1-0 ed.). Mainz have some interesting players and a good team."

“As far as mentality and determination are concerned, we have nothing to reproach ourselves for,” Robert Andrich said up after the first home defeat for the Werkself this term. In terms of their play, too, the Black and Reds put in a respectable performance for long stretches of this intense and physical match, outperforming VfB Stuttgart in most areas. It was only in terms of efficiency in front of goal that the Swabians had the edge over the Werkself. Head coach Carles Martínez wants to learn from this so that, in future, they can “win this sort of match too”. The Werkself review.
