The 29 year old defender, who arrived in Manchester from Spartak Moscow in a £7million switch four-and-a-half years ago, is relishing the experience of leading the side.
"It is a big achievement for me," said Vidic. "No-one is going to say they don't want to be the captain of Manchester United and I am very happy with it.
"It is a major responsibility but I have always liked responsibility.
"I am not a player who shies away from it. Nothing has really changed in that respect."
While Vidic is happy in his new role, he feels the true leaders at Old Trafford are veteran players such as Giggs, Neville and Paul Scholes, and regular captain Ferdinand.
"They are the real leaders. The other players follow how they do things.
"They don't have to do anything special. They just have to be themselves to be an example for the rest of the players.
"When they are not on the pitch, I just try to do my best and use the experience I have gained in the years I have played for Manchester United."
