The webchat will start at 12:00 GMT on Wednesday and end at approximately 12:30.
Although Vidic is still recovering from a season-ending knee injury sustained in Manchester United's Champions League encounter at Basel in early December, the Reds skipper has kindly agreed to field fans' questions in our exclusive webchat.
Ask him how his recovery going, what he's made of United's title challenge, when he expects to return to action... or, if you like, quiz him on his favourite film, what he enjoys to cook in the kitchen or where he'll be spending his summer holiday.
The fan whose question is considered to be the best by Nemanja will win a United shirt signed by the Serbian defender.
Nemanja Vidic will answer fans' questions in a live webchat from United's Carrington training base.
