The 36-year-old admits his playing career at Old Trafford is nearing an end and admits he would be keen to take over as manager at the club.
He said: “I think I will probably finish my career here.
“I am at an age now where it is coming to an end pretty soon. I cannot see myself dropping down leagues and playing at a lesser level.
“If you do decide to go into management, for me the ultimate jobs are Wales and Manchester United, purely because I have played for my country and for the team I supported. Those two would be the best ones for me.
“If that was to happen I shouldn’t think I’d be able to take over straight away. So if I was to go into management I would have to go elsewhere and be very successful – then come back.”
