Marten de Roon, born on 29 March 1991 (age 35), is a Netherlands international defensive midfielder whose career has been shaped far more by endurance than noise.
There was a useful English detour at Middlesbrough in 2016–2017, where he scored four league goals in 33 appearances, the most productive league season of his career. It did not alter the wider direction of things. De Roon’s football has been overwhelmingly tied to Atalanta.
Across 10 seasons with the Bergamo club, he has made 340 league appearances and scored 20 league goals. That tells the story plainly enough: a long-serving, reliable central presence rather than a player built around highlights. Wearing number 15, he remains part of the furniture without quite sounding like the furniture.
His relevance has carried into 2025–2026. De Roon has made 34 Serie A appearances with one goal, added four Coppa Italia appearances with one goal, and played 12 times in the Champions League. Across all competitions for Atalanta this season, he has made 50 appearances and scored twice.
His current market value is around £6m, according to Transfermarkt. At 35, de Roon remains a regular Atalanta first-team player, with a career defined by long service, position sense and steady usefulness.
