Mathys Detourbet

In September 2025, reports indicated AS Roma made a bid of €10 million, including €2 million in bonuses, which was rejected by Troyes. More recently, in January 2026, a potential transfer to Manchester City was reportedly valued at approximately €10 million. Across this period, the player's Transfermarkt valuation was consistently cited at €4 million.

Our valuation for Mathys Detourbet is driven by AS Roma's rejected bid of €10 million in September 2025, which establishes a firm baseline. This is reinforced by reports in January 2026 of a potential €10 million transfer to Manchester City. Widespread interest from other top-tier clubs and his international status suggest Troyes will hold out for a fee above the rejected offer, justifying our higher estimate.
