Chelsea Sign Mamadou Sarr From Strasbourg

Mamadou was a regular for Strasbourg during the 2024/25 campaign and played a key role in the French team securing qualification for European football next season.  

The 19-year-old made 28 appearances across all competitions and helped the club seal a place in next season’s UEFA Conference League play-off. 

Mamadou, a France Under-20 international, joined Strasbourg last August and quickly established himself as a regular starter in defense. He made 27 starts in Ligue 1 as Strasbourg claimed a seventh-place finish. 

Chelsea is delighted to confirm the transfer of Mamadou Sarr from Ligue 1 side RC Strasbourg, with the defender signing a contract until 2033.

Welcome to Chelsea, Mamadou Sarr!  🔵
