"My hope is that I can assist Gordon through my own experience in the game and that I can help the young lads to progress, become better players and better human beings," said Petrov. "There are important values that we have always stood for at the club and we will continue to do so.
"The main thing for me, however, is that it is not for sentimental reasons that I will be taking up this role but because I have something to contribute."
Petrov who also played for CSKA Sofia, joined Villa in 2006 from
Celtic for £6.5m,
having spent seven seasons in Scotland.
Villa manager Paul Lambert added: "I'm delighted that Stiliyan will be assisting Gordon when the new season gets under way and, as much as he's offered this football club in a distinguished playing career, I know he'll have more still to offer in the years to come.
"His qualities will be put to good, practical use now and he'll have a key role to play for Villa, that's for sure."
