A 3-1 win for City ensured they moved 12 points clear of Arsenal at this early stage of the campaign, and Arsene Wenger's side are already looking adrift when it comes to a potential title tilt, leaving many of the club's fans frustrated.
With Mertesacker and Rob Holding unavailable it was a necessary if unwelcome move to start midfielder Coquelin at the back, but the Frenchman was far from the worse performer on the day, and some of his more regular teammates should take a long hard look at themselves after the clash.
The 26-year-old has barely been used in the league this season, having to make do with some game time in Europe and the EFL Cup, but his first 90-minute showing allowed him the chance to prove his doubters wrong and stake a claim for the matches ahead.
With Mertesacker expected back shortly his Arsenal teammate may quickly slip back onto the periphery, but he at least tried his best against a City side that has steamrollered practically every team they have faced so far this season.
After the match we took to Twitter to see what Arsenal fans thought of Coquelin's latest performance and you can read a selection of what we found below:
>>> Iwobi deserves more game time. Coquelin, whilst he did okay, shouldn’t be anywhere near an #AFC 11. Both CM dreadful. City are beatable.— James Bower (@TheBowMonster) November 5, 2017
Arsene got most things right today apart from the coquelin decision. Got the subs right with Lacazette— - (@Charlie_AFC) November 5, 2017
Our fans are just a bunch of idiots. Coquelin is good, but they don't understand football. pic.twitter.com/6smqsxpM9L— 黒の神々 (@K____Shima) November 5, 2017
As much a Coquelin is a me,e footballer, he was good today. Much better than Monreal and Kosc.— AFC Marco (@marco_gooner) November 5, 2017
Actually thought Coquelin was one of our best players today. Saved us twice with good tackles.— SamW (@SamW_AFC) November 5, 2017
Coquelin was one of our better players today— ole (@gunnin4afc) November 5, 2017
Our best player on the day was Coquelin. That sums it up really— Mudit Jhamb (@afc_mj) November 5, 2017
