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."

It was a disappointing Saturday night. The Werkself lost 4-1 to VfB Stuttgart to start the new year on Bundesliga matchday 16 in 2025/26, a result that left both players and fans disappointed. "We played without any passion," said Alejandro Grimaldo honestly afterwards. Teammate Jarell Quansah was even more self-critical, emphasising: "We were miles off it in the first half. You can't put in a performance like that, especially in front of our own fans and I can only apologise to them, to be honest."
