Rooney was handed the role from the start and emerged as the best player on the pitch.
He said: "I played there a lot when I was younger and it's something which means you get a lot of the ball and we had to defend at times as well tonight. The manager asked me to do it and I'm happy to do it.
"I've said before I feel I'm a good enough footballer to play anywhere on the pitch.
"I'm not being big-headed, I feel I am capable of doing that and if the manager wants me to play there, I've no problem doing that."
