The French defender endured a tough debut season at Etihad Stadium following a £32million move from FC Porto but now feels right at home at the Etihad Stadium.
"I feel at ease, I have everything in my own hands in order to achieve good things. There is no more transition, or unknown things," he said.
"I know everything by heart, I've adapted to the lifestyle here, to how the club works, to the other teams or to the league.
"There are no problems any more, I have everything I need to achieve great things with Manchester City."
