Kevin Doyle says Mick McCarthy's decision to rest 10 players in the defeat to Manchester United was proved right by Wolverhampton Wanderers' 2-0 win over Burnley.
A fresh Wolves side dominated thoughout as goals from Nenad Milijas and Doyle lifted the Midlanders out of the relegation zone and deepened Burnley's away-day crisis.
The win came just days after Wolves boss McCarthy was roundly criticised for changing all 10 outfield players in the 3-0 defeat at Manchester United.
Speaking to Sky Sports News, Doyle said of the midweek rest: "It showed, didn't it? We were sharp from the off.
"I think we were the better team throughout. We sat back a bit and we were the fresher team.
"It's amazing what a couple of wins do.
"People were writing us off only a few weeks ago but we've got three important points and three important wins. Hopefully it will be a nice Christmas."
The Irishman celebrated his strike in freezing conditions by stripping off his shirt but even the predictable booking could not wipe the smile from the goal-hero's face.
"It doesn't feel cold after you score a goal, you don't feel a thing," he smiled.
