Defeat in Basel in midweek condemned United to the humiliation of life in the Europa League.
But Wayne Rooney and Nani both bagged doubles as the Premier League champions roared to a 4-1 victory over Wolves at Old Trafford.
And Fergie was quick to praise England ace Rooney for ending his goal drought to take his tally for the season to 11.
The United boss said: "Wayne in particular, does go in spurts. He scored nine in the early part of the season.
"Now we are going up to an important part of the season, if we get the goal ratio again, it puts us in good fettle."
Ferguson was delighted with the performance of his players and believes their European humbling could turn out to be a positive.
He added: "We will take a lot of stick from critics and even from people we thought were perhaps on our side.
"But this was the right response. Some of the football was fantastic."
After seeing his side humbled, Wolves boss Mick McCarthy laughed off suggestions that United had been on the verge of a crisis before kick-off.
McCarthy said: "All the hype and talk about their demise is nonsense.
