Romain Del Castillo

In August 2026, reports indicated an agreement was reached for a transfer to Osasuna for a fee of €1 million. Throughout January and August 2026, his Transfermarkt value was consistently reported at €7 million. Earlier, in January 2026, Nantes was reportedly interested but lacked the financial capacity to make a move.

Our valuation for Romain Del Castillo is primarily driven by the strong report from August 2026 of an agreed €1 million fee with Osasuna. While his market value is estimated much higher, this concrete transfer figure for the 30-year-old winger, who is reportedly seeking a move, provides the most realistic basis for his current price.
