In his first month in the league, Haaland scored nine times in just five matches.
The Norwegian striker bagged back-to-back hat-tricks against Crystal Palace and Nottingham Forest in the final two games of August, after scoring twice on his debut against West Ham United and once in the draw with Newcastle United.
His goals helped City to four wins and one draw in that period, as we began the defence of our Premier League crown.
The No.9 has continued his rich vein of form into September too, scoring three times in two matches already this month.
If he is to win the award, he will have to hold off the challenge of fellow nominees Pascal Gross, Gabriel Jesus, Aleksandar Mitrovic, Martin Odegaard, Nick Pope, Rodrigo Moreno and Wilfried Zaha.
