Mamadou Sarr

In July 2026, Transfermarkt reportedly estimated his market value at €22 million. His transfer from Strasbourg to Chelsea in summer 2025 was subject to varying reports, with fees mentioned at €12 million, €14 million, and up to €20 million, with the latter figure sometimes noted as including bonuses. The completed transfer history lists a €14 million fee for that move in June 2025. Prior to that, his transfer from Lyon to Strasbourg in August 2024 was for a reported €10 million.

Our valuation is driven by Mamadou Sarr's transfer to Chelsea in 2025 for a fee reported between €14-€20 million, his long-term contract until 2033, and the club's clear belief in his high potential, as shown by his early loan recall. The most recent market value estimate of €22 million provides a solid baseline, with his trajectory suggesting further appreciation.
