Kompany credits Mancini for the improvements made at City, saying the Italian's "obsession" with getting better has driven the players on.
"He's a very passionate man - there's no mistake about that," the Belgium defender said. "What you see on the touchline is the man you get. He knows his football.
"He's obsessed - in the same way a lot of players are in our team - with victory and getting better and making sure that even when we win we're not looking back on the positive things but also on the things that went wrong so we can improve."
