Lucas Stassin

According to available data, Lucas Stassin joined Saint-Étienne for a reported €10 million in August 2024. By mid-2025, the club's asking price was reportedly around €20 million, and a bid of €17 million from Rennes was rejected in August 2025. In September 2025, reports indicated Saint-Étienne rejected a €29 million package from Paris FC and a €25 million (plus €12 million in bonuses) offer from CSKA Moscow. Following this, the club's asking price reportedly increased significantly, with figures between €35 million and €42 million quoted to interested clubs like Stuttgart and Lazio into late 2025 and early 2026. Transfermarkt's valuation was cited multiple times, ranging from €7 million to a more recent €15 million.

Our valuation is driven by Saint-Étienne's consistently high asking price, which escalated to the €35-42 million range in late 2025. The most significant data point is the reported rejection of a substantial €29 million package from Paris FC in September 2025. This rejection, combined with Lucas Stassin's strong performance and long contract, establishes a high floor for any potential transfer, suggesting a final fee would likely fall between the highest rejected bid and the club's firm asking price.
