Rio Ferdinand has revealed the big practical joker at Manchester United is Darren Fletcher.
He told manutd.com: "The sly joker is Fletch. People don't suspect him, but when something's going on he is normally involved. Pique and Fletch are always at the centre of pranks with player's clothes.
"Me? I don't get involved. It's not my game. I'm a very mature member of the squad now so I don't get drawn into the young boys' antics!"
