"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."
