Mamadou Sarr

In August 2024, Strasbourg acquired the player from Lyon for a reported €10.0M. Leading up to his next move, reports in early 2025 mentioned a pre-agreement with Chelsea for €14M, while others suggested a potential fee of €20M, possibly including bonuses. The transfer from Strasbourg to Chelsea was completed in summer 2025, with reports citing figures of €12M, €14M, and €20M. The official transfer history records this fee as €14.0M.

Our valuation is driven by the recently completed transfer of Mamadou Sarr from Strasbourg to Chelsea in summer 2025. Available data consistently places the fee in the €12M to €20M range, with the official transfer history and multiple reports citing a base fee of €14M. This reflects a clear appreciation from the €10M fee paid by Strasbourg to Lyon a year earlier.
