The Red Devils finally ended the worst-kept secret in football when Van Gaal was formally announced as the new boss on Monday afternoon.
Van Gaal will swoop into Old Trafford after his World Cup duties are over with the Netherlands, with Ryan Giggs ending his 24-year playing career to take over as assistant to the current Oranje boss.
Speaking to Sky Sports News, Beckham hailed the "pedigree" of the former Bayern Munich and Barcelona boss, and thinks he is the right man to lead the Red Devils back into the Champions League after a disastrous campaign last term.
The former England captain said: "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. 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."
Beckham, who won six Premier League titles, two FA Cups, and the Champions League during 11 trophy-laden years at Old Trafford, wants to see the Class of '92 involved in the new-look coaching set-up.
"It will be great to see if Scholesy (Paul Scholes), Butty (Nicky Butt) and Phil Neville can be involved," Beckham added.
"When I saw them all sat on the bench it was an amazing sight and it was one that made me emotional - I've spent my whole career with these lads."
