Atalanta captain Marten de Roon is presented as a potential defensive midfield option for Ajax, where the 42-time Dutch international could mentor young players such as Sean Steur and Jorthy Mokio. The veteran, who will turn 35, is noted as a player who often does the hard work for others, a quality that reportedly led national coach Ronald Koeman to reconsider him for the Dutch team. De Roon has scored one goal for his country and has been with the Italian club since 2017, winning the Europa League in 2024. His contract is set to expire on June 30, 2026. In the current Serie A season, he has registered one goal and one assist in 26 appearances. Transfermarkt estimates his market value to be €3.50m.
