Barcelona and Real Madrid Target Jon Martín: €50M Release Clause Could Block Transfer from Real Sociedad

Barcelona and Real Madrid are already planning ahead for the next transfer window, with Jon Martín emerging as a defensive target — but his high release clause at Real Sociedad could make a deal difficult.

Despite strong interest from Spain’s biggest clubs, Martín’s future may remain in San Sebastián due to financial and contractual barriers.

💰 Jon Martín’s €50M release clause creates major obstacle

The 20-year-old centre-back has a reported €50 million release clause, a figure that could deter even elite clubs from making an immediate move.

Adding to the challenge, Martín recently extended his contract with Real Sociedad until 2031, giving the club full control over any potential negotiations.

While his market value is estimated to be lower, the release clause remains the key factor — and Real Sociedad are under no pressure to sell.

• Barcelona have lacked stability in defence, especially in high-pressure matches

Strengthening the back line has become a top priority for both clubs heading into the next transfer window.
