The one significant advantage Van der Sar feels Moyes has are the number of United players, past and present, with vast experience of winning trophies, who are still around the club.
"It is nice if you have players who win," he said.
"That is part of the history of Manchester United. (Paul) Scholes, (Gary) Neville, (Ryan) Giggs, (Rio) Ferdinand, (Nemanja) Vidic and (Patrice) Evra now. And (Michael) Carrick.
"It is good for any manager to have those types of players in their dressing room.
"You are trying to improve, changing players and filling in the gaps, but you don't have to build a new team all the time."
