United boss Sir Alex Ferguson played Rooney in a central midfield role on Wednesday night as United beat Otelul Galati 2-0.
The player revelled in it, won praise from his boss and believes that position could be an option towards the end of his career.
Rooney admitted: "It is probably a role I could enjoy in the future when I lose a bit of pace.
"It's a role the manager needs me to do at the minute and I enjoy it. I played there as a young lad. Having watched my team-mates, I understand the role."
