Mainz 05 triumphed in this fixture last season with a 3-2 win at the BayArena. For the Black-and-Reds it was one of only three home league defeats in total under Xabi Alonso, while for Mainz it's one of just two away wins in the league since October 2022. Bayer 04 came out on top in the last encounter though, winning 3-0 earlier this season.
The two sides have met competitively 36 times in total, with a slight advantage for the Werkself, who have won 19 games. Twelve have gone the way of Mainz, while just five have ended in a draw.
New boss Bo Henriksen, Mainz's third head coach of this season after Bo Svensson and Jan Siewert, got off to a perfect start with a 1-0 win against FC Augsburg last weekend. It ended a run of 11 games without a win and was only their second success of the current campaign. The Rhineland-Palatinate club, who signed Nadiem Amiri from Leverkusen in January, are particularly physical in their play. No side have contested more tackles per game than the 05ers this season (118). Two other stats underline this point: Mainz have registered the most fouls (298) and second-most cards (61).
