Mamadou Sarr

In July 2026, reports cited a Transfermarkt market value estimation of €22 million. The player's completed transfer from Strasbourg to Chelsea in June 2025 was reportedly for a fee between €12 million and €20 million, with official records noting €14 million. Prior to that, he moved from Lyon to Strasbourg in August 2024 for a reported €10 million.

Our valuation is driven by Mamadou Sarr's transfer to Chelsea in June 2025 for a fee reported between €14 million and €20 million, and a subsequent July 2026 Transfermarkt valuation of €22 million. Chelsea's high regard for the player, evidenced by a long-term contract until 2033 and an early loan recall, supports this appreciation. Current rumours focusing on another loan rather than a sale suggest the club is protecting a valuable, developing asset.
