Marten de Roon

The most recent valuation comes from August 2026, where a transfer fee of €1 million plus bonuses was reportedly agreed for his move from Atalanta to AS Roma. During the same period, his market value according to Transfermarkt was cited in reports as €3.2 million. A few months prior, in March 2026, his Transfermarkt value was noted as €3.5 million amid links to Ajax.

Our valuation is driven by strong reports in August 2026 of an agreed €1 million fee for Marten de Roon's transfer to AS Roma. This figure is considered highly credible given the player's advanced age (35), his expressed desire for the move, and the club's willingness to facilitate his departure. While his market value is estimated higher by Transfermarkt, the specific circumstances of this transfer point to a lower, nominal fee.
