Sir Alex Ferguson concedes Manchester United have been lucky in games this season.

Discussing the current season, Ferguson admitted United had at times been lucky.

He said: "I don't know how we are still unbeaten. We should have lost by six against Villa but in a way it was great because it was a reflection of what I have always believed in: when you give young people a chance they never disappoint you.

"That's what Villa did, they tore into us and had a fantastic belief in themselves. But we have a great group of young players at the club. We tend to go for younger players before older ones because they give you more loyalty."
