Ajax ace Dusan Tadic has no doubts Donny van de Beek will be a star for Manchester United.
The former Ajax midfielder scored on debut in United's opening day defeat at home to Crystal Palace yesterday.
Tadic told an Ajax website: "If you look at what Donny was like when I just arrived at Ajax (in the summer of 2018) and look at the player he is now, there is a world of difference.
“I have never seen a player develop like this. His work ethic has also improved enormously.
"I am proud that he has grown this way and I am sure he will do well at Manchester United."
