Mamadou Sarr

The transfer of the player to Chelsea from Strasbourg in summer 2025 was the subject of multiple reports. Figures mentioned for the deal included €12 million, €14 million, £12 million (approx. €14 million), and up to €20 million, with the official transfer history listing a €14 million fee. This move came after his transfer from Lyon to Strasbourg in August 2024 for a reported €10 million.

Our valuation is driven by the recent transfer of Mamadou Sarr from Strasbourg to Chelsea in June 2025, for which the fee was officially recorded at €14 million, with some reports suggesting it could be as high as €20 million. His subsequent positive development, including becoming captain at Strasbourg, winning the Africa Cup of Nations, and being actively recalled by Chelsea's manager, indicates his market value has appreciated since that transfer.
