The 24-year-old joined Leverkusen from Belgian side Union Saint-Gilloise in 2023 and was instrumental in his debut campaign at the BayArena, scoring 21 goals in 34 appearances as the German side lifted their first-ever Bundesliga title, won the DFB-Pokal, and finished as Europa League runners-up. However, the two ACL injuries he suffered, first in the 2018-19 season and then in the 2020-21 season, continue to be an issue for the striker. He missed 14 games last season due to multiple fitness problems. Following his failed medical, Boniface returned to Germany. Now, he has opened up on his battles with injuries and explained why his move to Milan ultimately collapsed.
