Wolves boss Mick McCarthy admits they were fortunate to defeat Bolton Wanderers 2-1.
Trotters substitute Johan Elmander pulled a goal back with 12 minutes remaining after Jody Craddock and Nenad Milijas had scored for the home side.
Craddock's goal came following a flick-on from Christophe Berra and even McCarthy admitted it was offside.
Serbian midfielder Milijas, a summer signing from Red Star Belgrade, extended Wolves' lead in the 63rd minute with a stunning strike after being recalled to the side.
It paved the way for their first win in nine games and came on the back of a disappointing defeat by Birmingham.
McCarthy said: "Nenad did not settle straight away. The Premier League is a bit of a harsh playground.
"I expected what I thought I was buying. He coped with what was a physical game today; he didn't when he first came.
"If he plays like that every week he will be in the team. If he doesn't, the rubber will come out.
"You need that class as well. You cannot run around for 90 minutes just huffing and puffing. His deliveries from corner kicks and free-kicks were sensational.
"It was a fabulous response to being beaten at home by Birmingham. It was essential we did that despite being embroiled in a scrap at the end.
"Our first goal was offside but I think we deserve a bit of luck. A decision went our way and not there's. I am the beneficiary of it."
