Scholes has been ruled out until the New Year with a knee injury, robbing Manchester United of their senior midfielder at a time when they are looking to depose Arsenal at the Premier League summit.

"The operation Paul has had on his knee has been 100% successful," Ferguson said.

"The surgeon has reported that the condition generally of his knee was excellent with no concerns.

"He will be back, refreshed and eager, in January. It will be like signing a new player in the transfer window for the second half of the season."
