Speaking to MUTV, he also explained why his former manager's philosophy for playing attacking football while blooding youngsters will undoubtedly impress Reds supporters.
"Louis van Gaal was my coach in the mid-90s with Ajax and we had a great period of success," Van der Sar said. "He always had an eye for young players and making them better while, of course, combining that with the players the club had already. That’s something that I expect him to do at United.
"Van Gaal’s style is similar to the way United want to play and the way United need to play for the fans because of the club’s history. I am sure he is going to find a way in terms of tactics needed to reintroduce that style and maybe bring a little bit of emphasis on the Dutch style of football.
"We had success in Holland and then he went to Barcelona and won the league. He also took Bayern Munich to the Champions League final and, unfortunately, they beat us (United) along the way and went through in the quarter-finals at Old Trafford with Arjen Robben’s goal.
"But I think his success shows his mentality, his approach and his work-rate is very high and he is also determined to make this work. With the people he brings in, they are also very capable. The goalkeeping coach, Frans Hoek, developed me when I was a young player at Ajax."
