Marten de Roon expects SC Heerenveen teammate Daley Sinkgraven to move to a bigger club next year.
The talented No10 is being tracked by Manchester United and Juventus, among several European heavyweights.
Young defender De Roon said: "He is so nimble, he almost dances on the field.
"With his left foot, he can do anything. Daley is a player for whom people come to the stadium to see.
"I hope and think that he won't leave in the winter, but in summer he will surely go to a big club."
