"We have signed a fast and penetrative winger in Callum Hudson-Odoi. He has everything to be able to help us immediately," said sporting managing director Simon Rolfes about the 21-year-old who will wear the number 17 shirt at the Werkself. "Callum has played over 100 games for Chelsea and proven himself in the Premier League as well as in the Champions League. This will give our attacking game another special component. We’re very happy this transfer has gone through."
The versatile Hudson-Odoi can play on either wing as well as in attacking midfield. "The move to Germany is really exciting for me and I can play in the Champions League with Bayer 04 Leverkusen," said the 1.77 metre right footer in explaining his transfer. "That combination is really attractive and I'm keen to get to know the club, the fans and the Bundesliga. Kai Havertz only had good things to say about it to me in the Chelsea dressing room."

Midfielder Ruby Grant is leaving Bayer 04 Leverkusen and joining Portuguese runners-up Sporting CP a year before her contract expires. The 24-year-old has been at the Werkself since January 2025.

He knows the dressing room, the pitch and the club. But, above all, he knows the feeling of playing for the Werkself at the BayArena: Moussa Diaby is back in Leverkusen after three years. The lightning-fast winger has signed a contract with Bayer 04 until 2031 and he will once again wear the number 19 jersey. The left-footed player previously played for the club from 2019 to 2023, having arrived in the Rhineland from his native France as a promising young talent and eventually leaving the club – having established himself as one of the Bundesliga’s best attackers – to join Aston Villa in the Premier League. Now he has returned to Bayer 04 from Al-Ittihad FC in Saudi Arabia.
