After settling in to life in Manchester, the Londoner would relish remaining at the club for the rest of his career, even though he's still only 21.
Smalling told Inside United: "I don't look too far ahead but I hope I can really get an established career and hopefully stay here for the rest of my life.
"I want to get more and more games as it goes on because I really feel part of this club. I'm really enjoying my football at the minute. The manager's got full faith in me and I want to reward that in the years to come."
