Hughes was sacked last weekend and took charge of the side for the final time in the victory over Sunderland, and there was widespread sympathy for the ex-Blackburn and Wales manager over the way his dismissal was handled.
There have also been reports that the likes of Craig Bellamy and Shay Given are deeply unhappy about the decision to replace Hughes and there had been suggestions new boss Roberto Mancini was facing a dressing-room revolt as a result.
However, Petrov has made it clear that, while he does not want to cause controversy as Mancini settles in, he is happy to see Hughes leave the club. Petrov scored the opener in the 2-0 win over Stoke and, having been dropped directly after scoring on two occasions under Hughes this season, he hopes his new manager adopts a different approach.
"Now is not the time to talk about my situation," he said, "but too many things have happened to me over the last six months and come the time, at some point in the future, I will tell you 100%.
"It would not be good for the new manager if I did it now, but what the old one did with me was not fair. I am just a football player. I cannot do anything apart from work hard on the pitch.
"I just hope after scoring this time I don't go to the bench because that is what seems to have happened every other time this season."
Petrov has made 11 appearances for City this season but made only four starts and, while he has had problems with his knee, he feels Hughes should have made much greater use of him.
"I have been away from Bulgaria for ten years now and sometimes I have had problems like this with other managers," he said, "but it is the first time I have not played for this long in my entire career.
"Yet in a funny kind of way I believe I can be stronger because of it. If you play and score and then carry on playing, it is easy. If you keep getting left out, it is not. I am grateful to my family and friends because it is only through them that I managed to get through it."
