Middlesbrough have confirmed that Marten de Roon is leaving their club.
Just one year after the transfer of Marten de Roon to Middlesbrough for 10.5 million euros, the midfielder returns to Atalanta. His purchase cost "Nerazurris" 13.5 million euros and 1.5 million in variables. The whole transaction can close at 15 million, but even without additional clauses, the Bergamans set up their transfer record. The biggest purchase ever in the club's history has been Luca Cigarini's purchase from Parma, worth €10.5 million.
The Dutch playmaker has developed immensely during one year in England. De Roon was one of the few bright points in the team. The 26-year-old was orchestrating the game of Boro last season, but also managed to score four goals.
The good form of Sparta Rotterdam trainee gave him the chance to represent Netherlands in November last year. De Roon made his debut in the colors of "Oranje" in a match against Luxembourg.
