A truly emphatic display at the Etihad Stadium saw City claim all three points to pile the pressure on league leaders Liverpool.
Aguero got City off to an incredible start, heading the Blues into the lead inside the first minute of the game.
Our lead didn't last for long though as Laurent Koscielny soon pulled one back for the Gunners to make it evens.
However, City's perseverance and pressure saw us go into the break with a 2-1 lead after Aguero netted his second goal of the game just before half-time.
The Argentinian added a third and final goal for City in the second half to secure his hat-trick and ensure that the Blues claimed all three points.
