United were not found wanting when they went 2-1 down to villa at home.
Ronaldo fired united back on terms with a fantastic goal. (which goal he scores isn't fantastic?)

And young 17 year old kiko macheda stepped up and scored the 3rd and winning goal for united 2minutes from time.

This is the hallmark of champions.
Form is temporary but class is permanent.
And united proved that theory right on Sunday.
