The Argie wrote in his column for The Sun: "There's a saying that is the same the world over, whether itâ€™s in Argentina or England â€” the table doesnâ€™t lie.
"So when we look at our Champions League group and see just two points from four games, you canâ€™t disguise the position weâ€™re in.
"But when I look around the City dressing room, I see a team of champions.
"And I see a team of fighters when weâ€™re backed into a corner.
"Itâ€™s going to be tough to get through to the knockout stages but we must draw strength from the memories of last season.
"The title was virtually at Old Trafford on the final day of the season but as a team we fought, we dug deep and Sergio Agueroâ€™s winner against QPR was a sign of our sheer mental strength.
"That made us champions and champions perform under pressure.
"There is a trust in the dressing room that makes us believe we can still turn things around."
