David Beckham has backed Louis van Gaal to be "great" following his appointment as manager of Manchester United.
The current Netherlands coach will take up the post at Old Trafford after the World Cup with Ryan Giggs as his assistant, after the Welshman confirmed his retirement from playing at the club.
The former United midfielder told Sky Sports News: "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."
Giggs spent the last four games of the season as the club's interim manager following the dismissal of David Moyes last month.
