The squad: New signing Skelly Alvero will be in the squad for the first time away at Mainz. Ole Werner will also have the trio of Jens Stage, Mitchell Weiser and Felix Agu, who were all still training individually on Thursday, available for the game. However, Werder’s head coach will have to continue to do without long-term absentees Amos Pieper (broken ankle), Milos Veljkovic (knee pain), Leon Opitz (ruptured ankle ligament) and Spyros Angelidis (broken hand). Additionally, Naby Keïta will be absent as he is still at AFCON with Guinea, with his side having progressed to the last eight.
Ole Werner on the game: “It’s a tough away game, one that will challenge us in every aspect. Mainz play and defend with a great deal of organisation. We know what we need to do, and now it’s up to us to produce it on the pitch again.”
