The Spaniard urged the Arsenal fans to stick behind the team even when things don't go to plan, although the past few seasons in north London have depicted a far from unified camp. Their opponents for Sunday, Manchester City, splurged only on Riyad Mahrez - an able option to back-up the tactically intelligent, yet much-maligned Raheem Sterling but Pep Guardiola already has a system in place with nearly the entirety of his squad well-versed in his preferred style of play.
After years of Arsenal largely playing the same way regardless of the opposition, Emery's approach at the Emirates will be somewhat more reactive.
Neither Kolasinac nor Monreal are expected to feature in the Gunners' season opener against defending champions Manchester City on Sunday afternoon. There's the promise of a more diligent, alert, tactically-astute brand of football with a higher press - and what better petri dish than a match against the runaway champions, a team that pounces on your weaknesses, insecurities and callowness more ruthlessly than anyone since. well. the Arsenal of 2000-2004.
Crucial to this game's outcome is how Emery approaches his first game.
Bernd Leno joined from Bayer Leverkusen to offer an alternative to ageing goalkeeper Petr Cech, while Lucas Torreira and Matteo Guendouzi have been bought to add energy and steel in midfield. The two had met on 10 previous occasions with Guardiola never losing a game against Emery.

"We are excited", he said. No way. I don't want to forget what we have done last season.

Catching City isn't the immediate target for the Gunners, who last won the title in 2004.
Emery was hired to replace Wenger following the Frenchman's exit at the end of a dismal campaign which saw Arsenal labour to a sixth place finish in the Premier League.
All 14 of Aguero's previous meetings with Arsenal have come during his time with Manchester City, including 11 in the Premier League which have yielded mixed results of four wins, four draws and three defeats.
