The 62-year-old was confirmed as the manager of the Old Trafford club on Monday. The Dutchman has promoted academy players into the senior team, especially in clubs like Ajax, Barcelona and Bayern Munich.
The former United midfielder remains hopeful that Van Gaal could do the same at Old Trafford.
“He has got a history of working with young players, bringing players through academy systems at places like Ajax. That can only be great for Manchester United,” Beckham told Sky Sports.
“As a Manchester United fan and for Manchester United as a club, to have someone like this with his pedigree – he has worked with some of the biggest and best players in the world.”
While United appointed Van Gaal as their next manager, Ryan Giggs ended his playing career and will be the former Barcelona and Bayern manager’s No 2 for the next season.
Beckham was a part of the Class of 92 along with Giggs and other payers. The Old Trafford favourite revealed that he was surprised by United’s veteran’s decision to end his playing career.
“I’m surprised he’s retired because he was still playing great. Physically he’s still in great condition, to play for so many years at the top level you have to be in great condition,” the former United midfielder said.
“Now he has a new role at the club and it was great to see him walk out as Manchester United manager for those four games. When you’ve got someone like Giggsy, who all the players respect and all the fans love, it makes a huge difference.”
“His role now has totally changed and I’m sure he will find it an easy transition because he takes things in his stride, he’s not affected by anything. He knows the club better than most people who are at Manchester United now,” Beckham said.
