David Beckham has revealed that he was forced to perform a sex act in front of his teammates as part of a football initiation.

According to the former England captain, as a 16-year-old he was egged on to masturbate while looking at a calendar of fellow Old Trafford legend Clayton Blackmore.

The father-of-four describes the embarrassing experience in a new documentary called The Class of 92, which chronicles his arrival in the football world with other Man United stars Nicky Butt, Gary and Phil Neville, Paul Scholes and Ryan Giggs.

"Everyone had an initiation that you had to go through on the youth team, that was one of the most uncomfortable ones," he told Metro.

"The fact that I had to look at Clayton Blackmore's calendar and do certain things while looking at Clayton Blackmore - I mean, it was embarrassing to talk about," he said.

The man known as Golden Balls has revealed that he would like Brad Pitt to play him in a movie about his life.

"Brad would be the obvious choice, I'd like Brad to be playing me," he told Talksport Radio.
