Cristiano Ronaldo 'flipped out' at Man United after David Beckham shirt number teasing

Cristiano Ronaldo may have been the guy at Manchester United – but his superstar status didn't protect him from dressing room ridicule.

Rio Ferdinand, who played alongside Ronaldo for six successful seasons, claims that he and his colleagues would use David Beckham's legacy to tease the young forward until he would "flip out".
