"When I was at United and Mark Hughes was playing, I was in awe of him, along with Paul Ince," Beckham told The Sun. "To be on the same training pitch as both of them was amazing.
"But he was exceptional for Blackburn and Wales before that. He will do a brilliant job at Manchester City. I am sure of that.
"He has been coached and watched by one of the best managers - if not THE best - in the history of football.
"When you have had that experience playing for United, when you have seen how Alex Ferguson watches players, coaches players and protects players, that can only help you as a manager.
"Incey is the same as Sparky. I never thought he would be a manager, either.
"He is a Cockney, like me, and I wish him all the best. He has enjoyed a surge to the top.
"For a while he tried to get a club, then he got into the game at Macclesfield, and now he is at a Premier League club with Blackburn.
"He will bring that experience from being at United and managing two football clubs.
"He will also have the respect of the players due to what he has done in the game. He will also bring the fun side.
"I saw that his fun side when, here in LA, I watched his Press conference on TV.
"He was asked about whether Blackburn would end up in the bottom three, and he said 'at least we're not in the bottom three ... yet'.
"I have no doubts the Blackburn players will love playing with him."
