Mainz, a top-tier football club in Germany, has been struggling to break out of the Bundesliga in recent seasons, often finishing below the top four. Their current season is no different: they are currently eighth in the Bundesliga, and their hopes of qualifying for the Bundesliga are slipping away. However, Mainz is poised for a moment of clarity, as they face a crucial match against Union Berlin, the top-tier German league side.

**The significance of the match**

Mainz has been struggling to break into the Bundesliga, often culminating from a series of poor performances and failures against top-tier teams.
