Gvardiol started all five of our league games in the month as we claimed the maximum 15 points.
He also added his first two goals in the division with a right-footed strike against Luton Town and a powerful header at Nottingham Forest.
The Croatian defender, playing mostly at left-back, is enjoying a strong first season in Manchester having already featured 37 times across all competitions.
The 22-year-old will face competition from Manchester United’s Bruno Fernandes, Arsenal’s Kai Havertz, Crystal Palace’s Jean-Philippe Mateta, Chelsea’s Cole Palmer and Everton goalkeeper Jordan Pickford.

Voting will close at midday on Monday 6 May, with the winner to be revealed on Friday 10 May.
Should Gvardiol emerge victorious, he would be the first City player to win Premier League Player of the Month this season.
