He told The Sun: "Of course I would want to stay, 100 per cent, provided I'm still playing like I am and feeling as good as I am at the moment.
"Manchester United is a great club, the No 1, and you would never want to play anywhere else if you can still play for them. United will always be in my blood now.
"People were writing me off when I was out injured and saying my career was coming to an end but I know my body and was confident I could get through it.
"I always felt that the more games I played in a row, the better for me - and it's worked out. I want to be able to contribute properly and be a player they actually need. You can tell if you're not really needed at a club any more. You just know.
"We are not in discussions about a new contract at the moment and I'm fine with that because of the understanding I have with the manager.
"I don't expect to be treated any different to the other older players like Giggsy or Scholesy, who normally sign on again at the end of the season."
