Manchester United striker Wayne Rooney has set himself a target of beating his best season scoring record of 23 goals.

Rooney found the net for the 15th time this season as he scored the first goal in Manchester United's 5-0 hammering of Wigan at Old Trafford tonight.

The result took the Red Devils to within two points of Barclays Premier League leaders Chelsea heading into 2010, just as Sir Alex Ferguson demanded.

"I would hope to beat my best total," Rooney said. "If I don't get another eight goals from now until the end of the season there is something seriously wrong.

"I hit the post before I scored and the bar afterwards. I am doing well and I feel fit. Hopefully that will continue."

Following on from his superb performance at Hull on Sunday, it was another masterclass from Rooney, which drew warm praise from Ferguson.

"Wayne was absolutely fantastic again, just like Sunday," said the United boss. "The energy he showed in his game and his desire is marvellous."
