"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."

The Werkself conceded a goal at home for the first time since the beginning of January 67 minutes into the game against FSV Mainz 05 on Saturday. Jarell Quansah levelled late on for the final score of 1-1 to secure a point and avoid a first home defeat in six games. Bayer 04 were very critical of their performance after the game.
