There was a change of personnel at the hosts at the start of the season: The club management at Mainz opted to change coaches after the second Bundesliga matchday. Achim Beierlorzer had to go after two defeats in the opening games and assistant coach Jan-Moritz Lichte took over the helm at Mainz 05. The former Werkself assistant coach under Sascha Lewandowski and Sami Hyypiä is looking to get the team back to winning ways – his opposite number Bosz obviously has something to say about that. Mainz have a lot of quality in their squad. It’s down to us to see that it takes another week before that is evident on the pitch,” the Dutchman declared.
In addition to Paulinho, who continues his rehab training following his torn cruciate, Bosz will have to manage without other players following the international break: Summer signing Santiago Arias suffered a broken leg and complex ligament damage to his ankle in a World Cup qualifier with Colombia and is set to be out of action for around six months.
The 56-year-old will also be without the services of Patrik Schick, who is struggling with a muscle injury. With Florian Wirtz, who was substituted in the middle of the first half of the Euro qualifier for the Germany U21s against Bosnia-Herzegovina, there is no evidence of a structural injury to his stomach muscles. The 17-year-old is already on the road to recovery. “But he probably won’t be available for us against Mainz,” said Bosz
In addition, Tin Jedvaj will also most probably have to miss out. The defender was not in the squad for Croatia’s 2-1 defeat against France on Wednesday night due to illness. The results of a coronavirus test proved to be negative and Jedvaj is now feeling better again.
In accordance with the regulations, the players returning from international duty undertook coronavirus tests at the BayArena on Thursday morning. Another round of tests will be performed on Friday morning. If the results are negative then the players can then take part in training and join the Bayer 04 group to travel to Mainz to hopefully play on Saturday and help secure the sixth Bundesliga win in succession against Mainz 05.

Around 400 active participants of all ages took the opportunity to experience the BayArena from a new and special perspective. And there was also plenty going on in the stands: The event attracted more than 1,000 visitors in total and provided an atmospheric end to the season.

Lying third in the Bundesliga, the Werkself made a faltering start in 2026 after the winter break, but gradually rediscovered winning ways and, as in the previous campaign, were among the top 16 in Europe and the top four in the DFB Pokal. In the Bundesliga, the Werkself also remained in the race for Champions League qualification right to the end. However, because setbacks repeatedly crept into the Werkself's performances between good displays and crucial games, it was not quite enough to secure a UCL spot in the end. A season with many ups and downs brought sixth place and qualification for the UEFA Europa League. Part II of the review of the 2025/26 season.

Following the final match of the 2025/26 season, the prevailing feeling was naturally one of disappointment after missing out on qualification for the Champions League. The Werkself finished the Bundesliga in sixth place, meaning they'll start the 2026/27 campaign in the Europa League. "But to talk negatively about everything now because of that would be wrong," stressed captain Robert Andrich following the final game, knowing that the past year at Bayer 04 was marked, more than almost any other, by the start of a new era and the courage to change – and in particular, the belief in a positive direction. Everyone was aware this process would need time. The first part of the 2025/26 season review.
