David Beckham: I wasn't world-class

English football star David Beckham has told the BBC that he was not insulted by his exclusion from Sir Alex Ferguson's list of four world-class Manchester United players - and he agreed.

Sir Alex said earlier this week that he only worked with four "world-class players" as boss of Manchester United - Paul Scholes, Eric Cantona, Cristiano Ronaldo and Ryan Giggs.

Asked if he was offended, Beckham said he agreed with Sir Alex, whom he called "the greatest manager of all time".

Now a Unicef ambassador, he spoke to the BBC's Laura Trevelyan at the United Nations in New York.
