Sem van Duijn

In August 2026, reports indicated that FC Utrecht negotiated a purchase option with AZ for a permanent transfer following a loan spell. This option was reportedly valued between €1,000,000 and €1,500,000. Around the same time, the player's market value was listed by Transfermarkt at €800,000.

Our valuation is driven by the strong report of a purchase option negotiated between AZ and FC Utrecht for Sem van Duijn in August 2026. This option, valued between €1 million and €1.5 million, provides a concrete and recent market-based assessment that outweighs the lower €800k Transfermarkt valuation.
