The 29-year-old, who is thought to be among the favourites to win the role permanently under England boss Fabio Capello, played down the importance of the role in terms of preparation.
"The way you prepare for a game shouldn't be dictated by whether or not you have an extra piece of cloth on your arm. You just go out and do what you normally do," he told Inside United magazine.
"That's what's won you the captaincy in the first place, so why change it? It's a privilege to be the captain and lead the team out, but I don't change anything.
"I just try and be myself. I talk quite a bit anyway during the game and in the changing room, so I just try and continue that and obviously lead by example on the pitch.
"You play to the best of your abilities and give 100 per cent and if your team-mates see you, the captain, doing that then it might inspire them a little more."
