Wayne Rooney Calls Transfer Request Saga His 'Biggest Mistake'

Manchester United striker Wayne Rooney admits handing in a transfer request two years ago was the biggest mistake of his career.

Rooney issued a statement in September 2010 in which he questioned the Red Devils' ability to attract top players and indicated he wanted to leave because the club could not match his ambitions.

Two days later, though, the England international performed a dramatic U-turn and signed a new five-year contract at Old Trafford.
