Mats Deijl

In January 2026, reports surrounding the transfer to Feyenoord contained conflicting figures. The general director of Go Ahead Eagles stated the fee was 'at least one million euros'. Concurrently, other media reports suggested a much lower fee of €300,000. The player's Transfermarkt market value was also cited in January 2026 and June 2025 reports as being €2,000,000.

Our valuation is driven by the imminent January 2026 transfer of Mats Deijl to Feyenoord. The strongest evidence is the selling club's director stating the fee is 'at least one million euros', which sets a firm floor. This is contrasted by a lower media report of €300,000, which we consider less likely given the player's status as captain, his long contract until 2028, and Feyenoord's immediate need for an injury replacement. The €2 million Transfermarkt value provides a reasonable ceiling for the deal.
