"The professionalism and determination, he showed every day in pursuing his career, was really exceptional. Moussa has made his mark on our team in recent years with his unique style of play and incredible pace. With a special style of play, he's a person who has his heart in the right place. We will follow his future closely and wish him great success," said Rolfes.
Diaby scored 49 goals and provided 48 assists for the Werkself in 173 appearances. For the 24-year-old, Bayer 04 Leverkusen is "a really special club. I received so much support and time on the pitch as a very young player that I could become what I am today. Without Bayer 04 and all the teammates and colleagues, who have always supported me, it might not have happened so quickly," said Diaby. "Now I want to take the next step and start a new chapter. I will always be happy and grateful thinking back to my time in Leverkusen."

It was a disappointing night in Athens: The Werkself lost 2-0 away to Olympiacos on Matchday 7 in the league phase of the 2025/26 UEFA Champions League campaign. In a match that was intense and fiery from the outset, the high-pressing home side made the better start and took the lead through Costinha on two minutes. Although the Werkself had a number of chances to equalise, the clinical Greek side increased the lead to 2-0 shortly before half-time (45+1’). In the second half, Leverkusen once again gave their all and showed total commitment but, despite their best efforts, the Black and Reds were unable to break down the Olympiacos defence on the night.
