So with five wins and one draw last month, here are the trio of players up for the public vote...
Kevin De Bruyne
Kevin De Bruyne enjoyed a superb September before injury kept him out of the game against Celtic.
It began with a man-of-the-match display against Manchester United and he followed that with exhilarating performances against Borussia Monchengladbach and Bournemouth - the latter a game where the Belgian was almost unplayable.
His appearance in the second-half of the EFL Cup tie at Swansea steered the Blues to a 2-1 win and he was influential again days later as City returned to The Liberty Stadium to win again. He limped off with a hamstring injury during that game, but must be a strong favourite for the September award.
Last month's Etihad winner is again in contention for September's prize.
Raheem Sterling has enjoyed another fine month for City, scoring three goals with classy strikes against Bournemouth, Swansea and Celtic.
His displays have been one of the highlights of the campaign and his overall return of five goals and five assists so far make him a strong candidate to win the September poll.
Aleksandar Kolarov has enjoyed a solid start to the season with only the 3-3 draw at Celtic a blot on his September copybook.
The Serbian started the month with an excellent display at centre-back in the 2-1 win over United, was impressive in the 4-0 win over Monchengladbach and was again outstanding against Bournemouth.
He has switched between left-back and centre-half with ease this season and has earned a nomination for last month's prize.
Vote now for your favourite - one lucky UK-based winner will get the chance to present the award in person at the CFA later this month.
Voting closes noon, Thursday
