Rooney was reacting to veiled criticism by Sir Alex Ferguson in his new book.
He told Sky Sports 2: "I haven't seen him since he retired. I'm happy under the new manager.
"The new coach that has come in (has given me) a new lease of life, I'm really enjoy working under David Moyes."
Asked if he would respond to Ferguson's comments, he said: "No, I'm happy playing football. That's the past, I'm looking to the future."
