Earlier this week, Sinkgraven admitted that he was flattered to be linked with clubs such as Eredivisie holders Ajax and 20-time English champions United.
And Heerenveen star De Roon declared that his club team-mate can do anything with his left foot, backing a potential move to a big club.
“He is so nimble, he almost dances on the field,” De Roon told Voetbal Primeur.
“He can do anything with his left foot. Daley is a player, for whom people come to the stadium. I hope he stays during the winter, but in the summer he will surely move to a big club.”
Sinkgraven has scored three goals and made two assists in 13 Eredivisie appearances this season.
