Wayne Rooney believes his future lies in midfield and thinks he will drop back when he loses the sharpness to play as a striker.
Rooney, 26, had a spell as an emergency central midfielder in October and November 2011 and he feels it could become a permanent move, saying he would love to be a playmaker.
"I did my bit by dropping into a central midfield role when the team got hit by injuries last season," Rooney said in My Decade in the Premier League, which is being serialised by the Daily Mirror.
"The manager thinks I can do a job there and, with the likes of Tom Cleverley, Anderson, Michael Carrick and Darren Fletcher all missing games, he asked me to help out.
"When I get stuck into the action as a central playmaker, I love it. I get more of the ball, I'm involved loads and I even think about playing there permanently, but only later in my career."
The England international is the fourth highest goalscorer in United's history and still sees himself as an attacker now but hopes a switch further down the line could extend his career.
"In midfield I don't have to be as sharp as a forward," he said. "Once I feel that I haven't got the sharpness needed to get away from defenders, I'll probably drop back into midfield for a couple of seasons so I can still influence the game.
"In my heart I'd prefer it if I was playing up front, because I can still do a lot of damage, but the sacrifices don't bother me."
