Vitesse Arnhem technical director Marc van Hintum is tipping Mason Mount for big things.
The Chelsea midfielder spent last season on-loan with the Dutch outfit and this term is with Frank Lampard's Derby County.
Van Hintum enthused: "There are only a few players of that age with so much class in the world.
"Mason can do everything. I am convinced that he will grow into an English international. We could not stand up to (Frank) Lampard. Mount has done everything very nicely.
"His father called us: 'Vitesse was great, but Mason really wanted to work with his idol'. We could understand that."
