The Italian hasn't heard from anyone at City since his sacking before the end of last season.
"Have I heard from the club? When a story is over, it's over. City are improving, as a few years ago they weren't even in the Premier League, but they won it with me," Mancini told the Gazzetta dello Sport.
"I'd say Manchester City are a bit like Juventus - they're growing, but are still a bit behind the big European clubs. To win the Champions League you need experience and the right squad. There aren't many games, so if you get two wrong then you're out of the running."
