The Gunners striker scored a superb goal for Unai Emery and co against their bitter North London rivals at the Emirates Stadium.
The France international netted against bitter rivals Tottenham Hotspur at the start of last month, halving the deficit for Unai Emery's charges en route to a 2-2 draw at the Emirates Stadium.
Lacazette's goal was something special, latching on to Nicolas Pepe's pass from just inside the box, getting the better of two defenders and lashing a ferocious strike into the top of the net - and then, the celebration.
Arsenal confirmed the news on Wednesday, the 28-year-old getting 39 percent of the vote and seeing off competition from Pierre-Emerick Aubameyang, who got 24 percent for his free kick against Aston Villa.
Bukayo Saka's effort against Eintracht Frankfurt came third, with Gabriel Martinelli's header against Nottingham Forest in fourth and the Gabon star's first against Watford in fifth, as per the Gunners website.
Here is what some Arsenal fans made of the update regarding the currently sidelined striker on social media:

That goal and celebration summed up my anger at Emery's funny formation (not the first time) that day. Just like Lacazette, I couldn't even celebrate the magnificent strike. I just sat there, wondering that we should be doing more damage to Spurs with the right formation.— Cyba_Omo_Law (@CybarIfeLove) 9 October 2019

Lacazette joined Arsenal from Lyon in the summer of 2017 for a then club record £46.5million fee on a five-year deal reported to be worth around £182,000 per week (Spotrac).
