In February 2026, reports claimed Olympiacos paid Rio Ave a €5 million transfer fee. Just prior, in January 2026, Rio Ave was reportedly asking for €20 million, while his Transfermarkt value was listed at €8 million. In December 2025, Rio Ave's valuation was said to be around €15 million, with Transfermarkt listing his value at €6 million at the time. The player's permanent move from Vasco da Gama to Rio Ave in July 2025 was completed for a reported €3 million fee.

Our valuation is driven by the strong and specific reports from February 2026 indicating that Olympiacos completed the transfer of Clayton Fernandes Silva for a €5 million fee. While Rio Ave had reportedly set much higher asking prices of €15-20 million in the preceding months, the final reported sale price is the most concrete evidence of his market value. This figure also represents a logical appreciation from the €3 million fee Rio Ave paid to acquire him permanently in July 2025.
