Ahead of Rio Ferdinand's testimonial, former Reds favourite John O'Shea pays tribute to his ex team-mate in an exclusive column for ManUtd.com...
"When Rio arrived at Old Trafford, looking like John Travolta in that suit, my first impression was that his dress sense was terrible. But you could see he was a classy guy and he soon became a vital part of Manchester United's success.
To be fair, he was usually well dressed and his personality was also so infectious in the dressing room. Of course, there is a fine line between confidence and arrogance, but Rio was always clever and intelligent enough not to cross it - he let his football do the talking.
Because he was so vocal, it was easy to develop an understanding and his partnership with Nemanja Vidic is still one of the best in Europe. Fans compare Vida's toughness with Rio's skill, but believe me, there isn't a centre-forward who would say Rio is a soft touch. He has a mixture of strengths and could be a bit nasty when he had to be.

Fans ask where he ranks amongst the great United defenders, and I have to say he's got to be up there. It's difficult to
