Manchester United boss Sir Alex Ferguson was delighted to see Wayne Rooney score his 100th and 101st United goals in their 5-0 win at Wigan.

Ferguson said: "It is a great achievement and he is only a young lad.

"Some players have been at the club for many years and not reached that total yet. It will do him a world of good.

"Strikers have to score - that is their mantra. If they are not scoring they think the world is at an end.

"When they are scoring they think they will never finish scoring. But that is what they are."
