The north London side welcomed Leicester City to the Emirates Stadium on Monday night following six successive Premier League victories to hoist themselves up the table.
Arsenal were behind in the 31st minute when Hector Bellerin scored an own goal to threaten to bring to an end their incredible winning run under the Spanish head coach.
However, Mesut Ozil inspired an Arsenal comeback with an instinctive finish on the stroke of half-time to restore parity before he created Pierre-Emerick Aubameyang’s 45th-minute finish.
The retired Germany international even played a big role in the January signing’s second goal of the night, with two clever flicks before Aubameyang netted for the sixth time in the Premier League this term.
Arsenal moved level on points with Chelsea FC on 21 points after their victory, although the Blues are ahead of the Gunners by virtue of their superior goal difference.
Emery’s men are just two points adrift of Premier League leaders Manchester City and Liverpool FC after nine games to fuel talk of an unlikely Premier League title challenge.
Speaking to BBC Sport following Arsenal’s entertaining 3-1 comeback win, Emery was quick to pour cold water on talk of the Gunners getting their hands on the Premier League trophy for the first time since 2004.
“We have every match as a big challenge,” Emery said when asked about a title challenge from his team this season.
“To continue wining is difficult and today is very important because Leicester are near us in the table. We’re only thinking of each match.”
The north London side will take on Liverpool FC in a crunch Premier League clash at The Emirates on 3 November after losing 2-0 to defending champions Manchester City in their season opener.
Arsenal turned to Emery to take over the reins from Arsene Wenger in the summer after the Frenchman led the Gunners to a disappointing sixth-placed finish in his final campaign in charge.
The north London side haven’t won the Premier League crown since Wenger’s famous “Invincibles” team managed to complete the top flight campaign without losing a game.
Arsenal have had to make do with three FA Cup titles over the past 14 seasons.
