Marten de Roon, born on 29 March 1991 (age 35), is a Netherlands defensive midfielder whose career has been shaped overwhelmingly by Atalanta. He wears No 15 and has become a long-serving fixture there rather than a passing import.
His one major detour came with Middlesbrough in 2016-2017, where he scored four league goals in 33 appearances. It remains his most productive league season, though not the spell that defines him.
At Atalanta, de Roon has made 340 league appearances and scored 20 league goals across 11 seasons. His value has been less about decoration than reliability: a central midfield presence, usually doing the work that keeps the side functioning. His current market value is around ยฃ6m, according to Transfermarkt.
He has remained firmly involved in 2025-2026, making 50 appearances in all competitions for Atalanta and scoring twice. That includes 34 Serie A appearances with one goal, four in the Coppa Italia with one goal, and 12 in the Champions League.
De Roonโs career is a straightforward one to read: a brief Premier League spell, then a long and continuing body of work at Atalanta, where he is still a regular first-team player.
