Manchester United prodigy Ravel Morrison has allegedly been accused of stealing teammate Rio Ferdinand's watch.

The 18-year-old, who was the subject of a rejected bid from Newcastle United today, has endured allegations of theft on social networking site Twitter, which has forced the player to seek out Ferdinand to deny such claims.

Morrison tweeted to Ferdinand: "I ever taken your watch because a lot of silly immature people with no life, with a lot of time on their hands seem to thinks so?"

The highly-rated winger continued: "People that make silly lil lies up have nout goin for them in their lives. Grow up, find something better to do & stop causing trouble."

The teenager pleaded guilty to charges of witness intimidation in court last year.
