The 30-year old Ivory Coast international, formerly of Monaco and Barcelona, beat off competition from four other nominees - John Obi Mikel, Victor Moses, Pierre-Emerick Aubameyang and Jonathan Pitroipa - to win the award for the first time.
"To join such a great list of names to have won the award in the past, it's an incredible feeling," he said.
"When I first signed at City at my first press conference, I said I came here to achieve a lot of things and this is part of that. Personal and collective achievements.
"Football is all my life, when I hear fans singing my name, I never want to stop. What the club and the fans have given me here is unbelievable - it's massive."
