Rafael van der Vaart has told Donny van de Beek: You’ve bitten off more than you can chew in joining Man United.
The ex-Spurs ace told ESPN: “United could be a step too high for Van de Beek.
“If nobody leaves United during the summer, he is going to need to get lucky to break into their starting eleven.
“He is much too good to remain sat on the bench for two seasons. He needs to get regular playing time soon.
“He is still young, but the time is flying past. Joining a club like Borussia Dortmund would have been better for him.
“Donny was a perfect fit for Ajax’s system, but he does not fit in at United.”
