The Spanish midfielder has struggled to establish himself under City manager Manuel Pellegrini.
But he told the City matchday programme: "There have been times when it hasn't been easy. Sometimes, in the quieter moments of the game, you can hear that the fans maybe aren't happy with you but things have been different recently and I know and have heard them really getting behind me which helps me even more.
"It hadn't happened that often but against Cardiff and Chelsea things felt much better and I put that down to playing more regularly and in turn, the fact I've played well in those matches."
