"Moussa Diaby is an extremely fast, technically strong striker whose qualities suit our game down to the ground," said sporting director Simon Rolfes after the second signing in the current transfer window following that of Kerem Demirbay. "Moussa is already very advanced at the age of 19. He played 34 games last season, an impressive number for a top European club like PSG. He's one of the really big French talents who will find ideal conditions here with us in Leverkusen to develop into an absolutely top player," added Rolfes.
Diaby, who will wear the number 19 shirt for Bayer 04, came through the youth ranks at Paris Saint-Germain and he was a regular for the French team at the U20 World Cup in Poland. The left-footer is happy "about a great chance to have a fresh start at a top German club where I can improve myself and my game. The move abroad into one of the best and most evenly balanced leagues in Europe is extremely exciting," said Diaby. "I'm very interested in Germany, the special type of football and the great stadiums. And of course, it's great to be in the Champions League with Bayer 04."
For Rudi Völler, the Diaby transfer means "we are once again a very attractive club for young top players. It's well known that you can quickly reach the highest level at Leverkusen and that we are willing to show our confidence and share responsibility early independent of age with appropriate performances," said the sporting managing director. "I'm sure Moussa Diaby will be really good for us with his great pace and his technique."

A fresh look for the BayArena: The Bayer 04 stadium will have new seating in the form of folding seats for the 2026/27 campaign that will ensure significantly improved seating comfort and simplified movement within the rows of seats. As part of routine replacement after 17 years, fans of the Werkself were able to purchase the existing seats, used to witness the first German league title in the club's history. In addition, a large proportion of the seats will be donated to charitable projects, primarily in the local region. Bayer 04 fans can look forward to new, functional folding seats for the season opener at the beginning of August - still in the club colours of black and red, of course.
