Sergio Martínez Montero

Reports from December 2025 mention a market value of €500,000 for the player. The same reports consistently state that his new contract with Racing Santander, which runs until 2029, includes a release clause valued at €3 million.

Our valuation is driven by the consistently reported €3 million release clause in Sergio Martínez Montero's recently extended contract. The significant interest from multiple clubs across Germany, Austria, and Belgium, including TSG Hoffenheim and Red Bull Salzburg, makes it highly probable that this clause will be met, establishing it as both the ceiling and the most likely transfer fee.
