Sagna joined City from Arsenal at the start of the season but has been reduced to a largely fringe role at the club due to the presence of Zabaleta.
However, Sagna told the Manchester Evening News, "I'm happy because I came to the champions. Zabaleta's been here for a long time, he's a great player.
"For me and for the manager it is maybe not easy to make the decision who's to start but every time I get to play I give the maximum for the team. I'm here to look forward and to progress and I think I did."
