Former Manchester United forward Tevez, 28, said: "I try to help Mario. I talk to him personally, on and off the pitch.
"I've been in that moment like him.
"I'm always keen to help him and keep him going through these kind of moments, so he doesn't make the same mistakes that I did in the past."
Tevez played down last week's training ground incident though and insisted he has seen similar things happen all over the world.
He added: "There are these kind of things that have happened at all the clubs I've been, but here at City the spotlight is always on us, as it is always on Roberto and Mario.
"So here it always comes out - but this kind of thing happens everywhere.
"Mario has been doing OK. He has been working and trying to improve, and you can always improve as a player.
"That's what he did coming back from illness and injury, and it's what he has been trying to do."
