Asked about his technique, he added : "This is my style. I feel great, so when I shoot like that, sometimes it is a goal, sometimes not.
"I'm very happy and proud to help my team."
United boss Sir Alex Ferguson was baffled they had not managed to score more than two goals.
"I think it was a fantastic performance - one of the best this season," he said.
"I can't believe it was only two. We missed a few chances, but at the end of the day you've got to think about the performance.
"We wanted to get back (to the top) - because it's a tricky part of the season now, with cup ties and European ties."
