Valencia CF has locked down one of La Liga’s most promising young defenders. Arnau Martínez, the 23-year-old right-back who came up through Girona’s academy, has signed a five-year contract that keeps him at Mestalla through 2031.
The transfer, finalized on August 25, is reportedly worth approximately 5 million euros in fixed fees, plus another 1 million in performance-related bonuses. Girona also secured a sell-on clause of between 10% and 15%.
A bargain shaped by relegation
Martínez previously had a release clause hovering around 8 million euros, but Girona’s relegation brought that number down considerably. Valencia moved quickly to capitalize on the situation.
Personal terms were reportedly agreed in early-to-mid August, with the formal club-to-club agreement following shortly after. Martínez arrived in Valencia on August 26 to complete his medical checks and begin integrating with the squad.
