Former Manchester United boss Alex Ferguson says he does not think anybody will break Wayne Rooney's United scoring record of 250 goals.

"In the present-day game, it is difficult to see any club having players who can stay with them for 10 years," said the Scot who signed Rooney from Everton.

"Bobby Charlton's record was quite substantial. I couldn't think anybody would beat that. It is an achievement par excellence."
