United were two-goals down at Old Trafford when they were given a penalty after Heurelho Gomes had brought down Michael Carrick inside the box.
“We were a bit fortunate but football is a funny game,” said Ferguson. “You get terrible decisions. We got one last week. You have to deal with them and get on with it.”
“It was a fantastic performance from Berbatov,” continued Ferguson.
“I don’t think he gave the ball away once. He was our best player in the first-half and in the second he produced some wonderful moments.
“He does things that are world class. All he has done is miss a penalty kick. It was a bad one, I make no excuses about that. But how many players have done that?
“It is only a missed penalty. We have to move on.”
