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).

Bayer 04 is using the home game against Mainz as an opportunity to organise the second Bayer Sports Family Match Day of the season. With this event and many others, the historic connection between Bayer 04, TSV Bayer 04 Leverkusen and Bayer AG is being passionately revived under the Cross. Numerous activities centred around the Bayer sports clubs and Bayer AG will provide a special setting today. The programme for the themed match day starts with the stadium opening at 18:30 CET in the area around the BayArena and offers a wide range of highlights. More information can be found HERE.
The German Football Association (DFB) has appointed Timo Gerach as the referee for tonight's fixture. The 37-year-old has officiated two matches involving the Werkself to date, with the Black-and-Reds winning both. Gerard will be assisted on the touchlines by Florian Heft and Robert Wessel, with Felix Zwayer as the VAR.

This year - for the third time - the parents of the Bayer 04 youth players from the U8 to U15 age groups once again took part in the WDR Christmas Miracle. Under the motto "Goals against hunger in the world - parents in goal!", they organised their own fundraising campaign to once again actively support the important WDR campaign. The sum of €3,420 was handed over at the Glashaus in Essen in the middle of the week during the live programme.
