The 62-year-old was appointed as the Red Devils’ new manager last week on a three-year deal and will officially take charge at Old Trafford after the World Cup.
And former United goalkeeper Van der Sar, who worked under Van Gaal during his spell at Ajax, is convinced that Van Gaal’s approach will be a big hit at the club.
“Louis van Gaal was my coach in the mid-90s with Ajax and we had a great period of success,” Van der Sar told MUTV.
“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.
“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.”
