The controversial Argie is on the brink of inspiring City to the title.
Wright wrote in The Sun: "Remarkably, Tevez could end up having a major say in the championship.
"I have never seen such petulance from a player who was an absolute disgrace and is lucky to be back playing again for City. There was some major back-tracking from a manager who said his player would never play for the club again.
"And maybe Mancini will wish he had done his talking about Tevez in private. Equally, you have to give credit to the City manager for swallowing his pride and allowing this character back into the fold.
"Mancini knows the guy is a top player. Tevez, as proved by his performances, has responded in a positive fashion. But Tevez is incredibly fortunate — not least because he appears to have been welcomed back into the dressing room with open arms, despite displaying such a shocking attitude.
"Mario Balotelli has also been fortunate to have been given numerous chances to redeem himself — after some of his antics on and off the pitch.
"And I think the Italian will look to sell his fellow countryman Balotelli in the summer yet keep Tevez."
