Tevez had his hopes of a quick exit from the Eastlands outfit dashed yesterday when City rejected a ?40million bid from Brazilian side Corinthians.
In addition to being ?10million below their asking price for Tevez, City were unsure as to how the payments would be structured.
It has left their captain in a state of limbo, committed to leaving in order to establish a more structured family life with wife Vanesa and his two daughters, who do not wish to relocate to England, and knowing the clubs who could afford to buy him are few in number.
And Dabo, the one-time City midfielder who was signed for Lazio by Mancini in 2003, feels Tevez has also underestimated his old boss' fierce defiant streak.
"Mancini won't be bullied by anyone, that is for sure," said Dabo.
"He will handle the situation very well.
"If he wants Tevez to go, he will let him go. If he wants him to stay, he won't let him leave."
Dabo is part of the New England Revolution squad that will tackle Manchester United at the Gillette Stadium this evening in the first game of their five-match US Tour.
It is a neat coincidence, given the man who infamously attacked him on the City training ground, Joey Barton, has been denied a US visa for Newcastle's short tour due to his criminal record.
"I don't want to speak about him," said Dabo. "It went to court and he pleaded guilty. It was over from that moment.
"I don't know what he is doing and I don't care."
Although the Barton incident stained his time at City, which by his own admission was also pock-marked by too many injuries, Dabo still has fond memories of his time in the north west, not least because his fiancee comes from there.
"I still follow Manchester City," he said.
"But it is amazing how things have changed in such a short space of time.
"Now there is only Micah Richards and Joe Hart from when I was playing. Every other player has left."
The familiarity for Dabo comes through Mancini, whom the Frenchman insists betrays his calm exterior with an inner steel capable of resisting the toughest of opponents.
"He has a big temper," warned the midfielder.
"He has to speak with big players who have a big ego. In that situation, you have to be strong because it is important to handle the team."
Under Mancini's tutelage, Dabo is convinced City will achieve far more than the FA Cup secured last May that ended a depressing 35-year wait for a trophy.
And he insists the Italian's reputation for dour, defensive football is undeserved.
"I saw a lot of games last year," he said.
"I don't think he is very defensive. They scored a lot of goals and played very well and it will only get better and better.
"City have so many players, so they can handle playing in the Premier League and the Champions League. In fact, I think they can win the league.
"Roberto has already won the title in Italy with Inter Milan so I am not worried about Manchester City.
"The future looks good for them."
