But speaking at the North West Football Awards, where Mancini was named Manager of the Year, Vieira said the speculation is purely as a result of the club's success.
"That is a part of the game," Vieira told
BBC Radio Manchester.
"You people, the journalists, try to find the little things that will sell more papers or get more people listening to the news. We accept it, no problem at all.
"Since he [Mancini] has been at this football club, his record has been fantastic. You don't win the FA Cup or the Premier League with an average manager. You have to be good.
"Everybody says we have a good team, but you have to manage 25 players. A lot of credit must go to Mancini because he has worked hard to bring silverware to the football club."
City have yet to win in the Champions League this season and lie bottom of their group with an extremely slim chance of reaching the knockout stages.
"Of course we didn't help ourselves and do ourselves any favours, but the door is not completely closed," added former France international Vieira. "It is going to be difficult and not many people believe we can go through, but we have to believe.
"The Champions League is a different level and it's new for us. We're learning and I believe we're going to get better, but it will take time."
