Wolves manager Mick McCarthy hopes his side's FA Cup third round 1-0 win at Tranmere will generate some momentum for the league campaign.
On a rapidly freezing pitch Matt Jarvis converted Nenad Milijas' brilliant through-ball in the 77th minute having previously missed an open goal from seven yards in the first half.
Crystal Palace now await in the next round but McCarthy is looking for a more immediate product from the win, saying: "We needed a win. I don't know what winning will do for confidence but I know what losing would have done for it - it would have had a real adverse effect."
He added: "I think we have been solid enough. I didn't think we would go there and dominate the game because you just don't in the FA Cup," said the Wolves boss.
"Where people find that extra bit I don't know but I bet that is the best they have played in a long time.
"They didn't allow us to pick them off. They defended well and had some good chances.
"I thought first half we were evenly matched but second half we were the dominant force and for long periods we were camped in their half - deserved winners I think."
Tranmere had taken every precaution - including covers and heaters - in the week to ensure the match would go ahead but with temperatures below freezing when the game kicked off at 6.15pm the players found the pitch difficult.
"I didn't realise till I walked on it at the end - it was awful. The referee (Lee Probert) said 'Credit to your lads' but I think credit to everyone.
"I thought it was a good game of football because conditions were difficult."
