Tevez had his hopes of a quick exit from the Eastlands outfit dashed yesterday when City rejected a £40million bid from Brazilian side Corinthians.
Tevez is desperate to leave the North West in order to establish a more structured family life with wife Vanesa and his two daughters, who do not wish to relocate to England.
But 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."
