Mick McCarthy is confident Wolves will reap the benefits of easing summer signing Stephen Hunt into action after injury.
The Republic of Ireland international was suffering from a long-term foot problem when he moved to Molineux from Hull City in the summer.
McCarthy has resisted the temptation to thrust Hunt swiftly into the fray and has held him back, with Saturday's 2-1 victory over Manchester City marking his first Premier League start of the season.
The Black Country boss believes that the former Reading man could prove to be a key player when Wolves make the testing trip to Manchester United on Saturday.
McCarthy said: "I think he'll be fine on Saturday and he'll be flying at Old Trafford.
"He's had two-and-a-half games and he's a fit guy. We nursed him back and made sure he was right and he'll get the benefit from that."
McCarthy believes the recent Carling Cup clash between the teams, when a much-changed United scraped a late 3-2 success, will have little bearing on Saturday's encounter.
He said: "It will be a different game. They'll have Nemanja Vidic, maybe Rio Ferdinand and Dimitar Berbatov and Paul Scholes playing against us.
"They have got players who will play that didn't play against us before. But we've got players as well that will come in.
"I don't know if Ryan Giggs will be fit, and I know they're saying Wayne Rooney won't be fit until they play Manchester City.
"They also had the Champions League game on Tuesday and, if that helps us, then great."
