Manchester United boss Sir Alex Ferguson believes Wayne Rooney was back to his best in their victory at Hull City.

Ferguson wants Rooney to maintain his form for tomorrow's clash with Wigan Athletic.

"Wayne was fantastic on Sunday. That was the Wayne Rooney we know," said Ferguson.

"He had a quiet spell for two or three matches but he was explosive at Hull. He was a constant threat.

"That is the kind of form we are hoping for because when he is playing like that, he is hard to handle."
