Gustavo Caballero

In February 2026, reports detailed a loan deal to Portsmouth that included an option to buy for approximately €5 million for 80% of the player's rights, implying a full valuation of €6.25 million. The same deal reportedly generated a €1 million loan fee for Santos. His market value was estimated at €1 million in April 2026. Previously, he completed a transfer from Nacional Asunción to Santos in July 2025 for a reported €1.3 million.

Our valuation is driven primarily by the recent loan agreement for Gustavo Caballero between Santos and Portsmouth in February 2026. This deal includes a reportedly realistic option to buy for €5 million, covering 80% of his rights, which implies a full valuation of over €6 million. This figure, agreed between two clubs, represents the most concrete evidence of his current market price, supported by his move to the English Championship and involvement with the Paraguayan national team.
