Dutch great Marco van Basten feels Donny van de Beek still needs to win over his Manchester United teammates.
Van de Beek has battled to make an impact since his summer arrival from Ajax.
Van Basten told Ziggo Sport: "It just shows what a great life they have when they play at Ajax. They all think very quickly that they are a big boy here and can make it in other countries, but in the Netherlands, there is a nice competition.
“In a team like Ajax you are really helped, especially in the No.10 position. Then you often see that they go abroad and it is a different story."
On what Van De Beek can do to improve his playing time at United, Van Basten said: “You have to be able to take care of yourself. If you go to a club in another country, you have to be able to present yourself in that team in a way that the others will think: he is one of us and with him we are going to win."
