The youngster signed from Ajax in the previous summer transfer window for £40.5million, but has yet to find his feet in Manchester.
“I do talk to a lot of people at the club," Van der Sar said of the former Ajax ace.
“[He has a] fantastic attitude, he does well in training.
“It [sealing a spot in the Manchester United midfield] is difficult.
“Pogba is coming back, Fernandes is very important, [Nemanja] Matic and McTominay, are also there.
“It's no shame at all, it's also a big club, isn't it?
“Of course, it's a large amount [Van de Beek's £40.5m transfer fee], but they are confident that he will get there."
