Mikel Oyarzabal

Across rumours from 2025 and 2026, a release clause of €75 million is consistently reported in relation to interest from Manchester United, Aston Villa, and Barcelona. In contrast, his Transfermarkt market value was cited as €25 million in several reports during the same period. Barcelona's reported view of him as a 'low-cost' opportunity in June 2026 suggests they would aim for a negotiated fee significantly lower than the release clause.

Our valuation for Mikel Oyarzabal is shaped by the conflict between his reported €75 million release clause and his much lower €25 million market value estimate. While the clause sets a firm upper limit, reports suggesting he is a 'low-cost' target for Barcelona indicate a negotiated fee is more likely. His long-term contract until 2028 gives Real Sociedad significant leverage, leading us to estimate a value substantially higher than the market valuation but below the full release clause.
