Nemanja Vidic says he is enjoying the added responsibility that comes with wearing the captain's armband at Manchester United.
Manager Sir Alex Ferguson named the Serbian defender as skipper at the start of the season and the side have since made an impressive start to the campaign.
United reclaimed the lead in the Premier League on Monday by seeing off Arsenal 1-0 at Old Trafford and extending their unbeaten start to the season to 16 league matches - a club record.
"I feel very proud," 29-year-old Vidic told United Review. "It came as a bit of a surprise but I am enjoying the role.
"You have to think about your responsibilities - your behaviour, the way you play, the way you train. I know that I need to set a good example on and off the pitch.
"In terms of my game I do not think anything has changed. I've always talked a lot on the pitch. You have to communicate as a defender and organise things whether you are captain or not.
"I tend not to think about it (the captaincy) when I'm playing. I am just focused on doing my best for the team as I have always done."
Vidic insists there are several leaders in the United squad that help him in the captaincy role.
"The likes of Rio (Ferdinand), Gary (Neville), Giggsy (Ryan Giggs) Scholesy (Paul Scholes), Edwin (Van der Sar) set the example," he said.
"The way they help the other players is fantastic. They have helped me develop and I want to help the younger lads do the same."
The stopper has a particular kinship with central defensive partner Ferdinand, adding: "Rio and I have a great understanding on the pitch.
"I also have to say Mladen Krstajic and I had a great relationship for the Serbian national team.
"I am not being disrespectful to the other players I've played with, but the results I've achieved with those two players shows what a good understanding we have. They have both helped me improve as a player."
