"Moussa Diaby has developed into a fantastic player in his time at Bayer 04," declared sporting managing director Simon Rolfes. "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."

Less than a year ago, Kerim Alajbegovic moved from the Bayer 04 U19s to Austrian top-flight club FC Red Bull Salzburg. The forward’s development since then has been impressive. In 36 matches, including in the UEFA Europa League, the 18-year-old has scored 14 goals. In the summer, Alajbegovic, now a Bosnia international, will return to Leverkusen - and thus not only achieve the next milestone still early in his career, but also enrich the Werkself squad with his footballing versatility and determination.
