The Reds were virtually home and dry by half-time at Molineux after first half strikes from Jonny Evans, Antonio Valencia and Danny Welbeck had provided a three-goal advantage against ten-man Wolves.
Javier Hernandez added two more after the break to ensure United made a sizeable dent in Manchester City's goal difference advantage, but the Reds' boss insists his side can still play better.
"What is significant today is we've reduced the goal difference by five goals and that may make a difference at the end of the season," he told Sky Sports and MUTV.
"It was an okay performance from us. I didn't think it was anything special although there was a great intensity about the players. They were all really concentrating on their jobs because they knew it was an important game. Wolves always make it difficult for you here, but we took our goals well.
"The finish for the second one was fantastic from Valencia. Antonio is back in the team and his form was fantastic today.
"He made one for Danny Welbeck [right on half-time] which killed the match really.
"The first 20 minutes were very even and competitive and getting the opening goal was a bonus for us. After that it was very difficult for Wolves with ten men and being 3-0 down. They were honest and committed in the second half and they kept plugging away, but the 3-0 advantage we had was too much for them."
The victory takes United four points clear of rivals City who are next in action on Wednesday night
