Cristiano Ronaldo used to admire himself naked in the Old Trafford dressing room

Get you someone who looks at you the way that Cristiano Ronaldo looks at Cristiano Ronaldo.

Nobody is a bigger fan of Ronaldo than the Juventus forward himself and he's not just immensely proud of his footballing talent. Ronaldo has also been a long-time admirer of his own looks and Peter Crouch has revealed how far the Portuguese superstar would take his vanity during his time in the Premier League. In Crouch's new book, the Stoke City forward has divulged a bizarre story that he'd heard from Rio Ferdinand regarding Ronaldo's behaviour in the dressing room at Manchester United. "Rio Ferdinand would tell us stories about how Cristiano Ronaldo would stand in front of the mirror naked, running his hand through his hair, and say, 'Wow. I'm so beautiful!'," Crouch wrote, via the Daily Mail . "The other United players would try to wind him up. 'Whatever. Leo Messi is a better player than you.' "And he would shrug his shoulders and smile again. 'Ah yes. But Messi does not look like this.'" With stories such as the above contained within, Crouch's autobiography How to be a footballer sounds like a must-read. We've already learned how Roy Keane managed to convince the 6ft 6in centre-forward to sell his Aston Martin just days after he bought it with one disapproving glare.
