In June 2026, reports stated the transfer from Troyes to Manchester City was completed for approximately €25 million. This followed multiple reports in May 2026 that a deal had been agreed for the same amount (€25 million, also cited as $29 million). In April 2026, one report suggested an agreement was reached for €15 million, while another claimed Troyes was demanding €25 million. Earlier, in January 2026, a potential transfer was valued at around €10 million. A reported bid of €10 million from AS Roma was rejected by Troyes in September 2025. Transfermarkt's valuation was listed as €10 million in May 2026, up from €4 million in January 2026.

Our valuation is driven by multiple, consistent reports from May and June 2026 indicating that a transfer for Mathys Detourbet to Manchester City has been agreed upon for approximately €25 million. This figure represents the upper end of our range and our final estimate. The lower end of the range is set at €15 million, based on a conflicting report from April 2026, but we place more weight on the more recent and frequently cited €25 million fee.
