Samuel Umtiti has retired from professional football at the age of 31. His career, especially the latter years, was severely affected by chronic knee problems, including cartilage damage. He began experiencing knee pain during the 2017-18 season and continued to struggle with it despite various treatments and even surgery. These issues limited his appearances for clubs like Barcelona, Lecce, and Lille in recent years. Umtiti was a key player in France's 2018 World Cup victory and had a successful spell at Barcelona, winning multiple titles. However, his ongoing knee injuries ultimately led him to stop playing professionally after leaving Lille and failing to secure a new team.
