Maas Willemsen

In August 2026, reports indicated that a 'multi-million euro bid' for the player was rejected by his club. Prior to this, in both January and May 2026, his market value was listed by Transfermarkt at €1,500,000. He originally joined his current club on a free transfer from De Graafschap to SC Heerenveen in July 2025.

Our valuation for Maas Willemsen is primarily driven by the rejected multi-million euro bid reported in August 2026. This, combined with growing interest from top Dutch, German, and Italian clubs and a long-term contract until 2029, places SC Heerenveen in a strong negotiating position, justifying a value significantly above his last reported market value.
