David Beckham agrees with Alex Ferguson's assessment that he was not a "world-class" player.
The former Manchester United manager's latest autobiography includes a claim that he managed only four players deserving of that description during his long Old Trafford reign.
Former England captain Beckham was a notable absentee, as well as former skipper Roy Keane, from a list which comprised of Cristiano Ronaldo, Ryan Giggs, Paul Scholes and Eric Cantona.
But asked if he was "insulted" by his omission, Beckham told BBC News: "Not at all.
"I played for the greatest manager of all time for the amount of time that I did, I was lucky to play with the players I did and be successful with the club that I loved and still love.
"I tend to agree with the manager. There's certain players that you can call world-class, thankfully I played with many of them.
"I'm proud as a Manchester United player that we were successful and I'm proud as a Manchester United player that we have the best players come to our team."
