Our Algerian winger was superb throughout December.
With four goals, three assists and a string of star man displays, Mahrez's influence this campaign has steadily grown each month and he is currently City's top scorer with 13 goals from 25 games.
More than 36,000 votes were cast for the December poll.
Now away with Algeria at the Africa Cup of Nations, Riyad will be presented with the award on his return, as well as sharing his thoughts in our regular Player of the Month interview later this month.
Congratulations to Riyad and thank you to everyone who took the time to vote.
