Rooney struck a brilliant opener in the first minute against Villa when he was found by a clearance from United keeper Edwin van der Sar and finished in style.
The forward later slotted in from a Nani cross to take his tally to four in the league this season.
"I have had a few chances off Edwin," Rooney added. "It is something we have been trying for the past few years. It was a great ball by him and thankfully I was able to put it away.
"It was also a great ball from Nani. That is something he can do really well and it would be great to see him do more of it.
Man Utd were brilliant - Houllier
"He has got great dribbling skills but he is also a great crosser of a ball. If he mixes that up he will be really difficult for defenders to mark."
Darren Bent pulled a goal back for Villa to make it 2-1 but a Nemanja Vidic strike restored United's two-goal advantage.
Villa boss Gerard Houllier conceded his team were beaten by the better side and warned that United will be a tougher proposition in the title race with an in-form Rooney.
"Wayne Rooney was the difference. He was awesome," Frenchman Houllier reflected.
"But we have helped his confidence. What he needed was a goal. We gave him one. He took it very well."
"They have managed to win a lot of games and remain unbeaten without him. With him, wow.
"He was on top of his game today. He had everything. He can control, turn, twist, play the pass. He defends, he works hard. It was an example for what kids should do - the work rate and link play, everything."
