Before the victory at Wolves, rivals Manchester City were eight goals ahead. Now the margin is down to just three, with the Reds four points clear of the Blues at the top of the table having played a game more.
"We knew we had an opportunity to score goals today," the striker told Sky Sports. "We spoke about it at half-time and wanted to push on and score more. We managed to get an extra two in the second half, so we're pleased with the result."
Rooney was also delighted with the attitude the team showed after the disappointing Europa League exit in Bilbao last week, and maintains that the team's impressive league form will stand them in good stead for the final push in the title race.
"This is a great result for us. Thursday was a disappointing night for us all and we knew it was important we bounced back and bounced back well," he added.
"Coming here over the last few years has been a difficult game for us so to leave with three points makes it a great day.
"I've said before today we're playing really well and getting the results we need. I'm sure if we keep doing that it'll be a good season for us."
