At Villa Park last weekend it was just one of those times when they fell two goals behind and then turned the game around on its head with a late, late winner from Hernandez.
This preserved United's lead at the top of the table and this weekend he lads are away at Norwich, another ground where they relied on a late winner from Ryan Giggs last term
Fergie admits that his side would not be able to do something like this every week, he does feel that the excitement generated by such games is unique.
"It does feel different," he told reporters.
"The dressing room is different when you get these late goals, or you come from behind. It makes an impact because there is more excitement. We have experienced it many times and it is credit to the character of the club that we can do it."
