Mamadou Sarr’s move to Chelsea Football Club is a big deal for the 19-year-old French defender, who has shown a lot of talent in his recent games. The transfer from Strasbourg to Chelsea was officially confirmed on June 9, 2025. This move was expected, as they reached an agreement back in January 2025 for a fee of about €14 million (£11.9m; $14.4m). The deal was completed today, with Sarr signing an eight-year contract that will keep him at Chelsea until 2033, as stated on the official Chelsea website.
Mamadou Sarr, who was born on August 29, 2005, is a central defender that has quickly become a regular starter. In the 2024/25 season, he played 28 times in all competitions for Strasbourg, starting 27 of those matches in Ligue 1, helping the team finish in seventh place. This achievement allowed Strasbourg to qualify for the UEFA Conference League play-off, showing how important Sarr was for the team’s defense. His performances received a lot of praise, with Strasbourg’s head coach Liam Rosenior saying he has “scary” potential and a “world-class” future.
Sarr’s spot in Chelsea’s squad for the FIFA Club World Cup, which starts on June 16, 2025, against LAFC, shows that he will have an important role in Enzo Maresca‘s plans. This tournament, happening in the United States, gives Sarr a chance to quickly fit in with the first team, possibly playing alongside defenders like Levi Colwill, Wesley Fofana, and Trevoh Chalobah.
