Sergio Martínez Montero

Reports from December 2025 and January 2026 consistently state that the player's contract includes a release clause of €3 million. A December 2025 report also cited a market value of €500,000. More recently, in February 2026, it was reported that both Barcelona and Real Madrid made formal loan offers that included an unspecified option to buy.

Our valuation is driven by the consistently reported €3 million release clause for Sergio Martínez Montero. The high level of interest from top-tier clubs, including formal loan-to-buy offers from Barcelona and Real Madrid, strongly suggests that any permanent transfer will likely meet or be very close to this clause amount, making it the primary determinant of his value.
