Sokratis, Lucas Torreira, Stephan Lichtsteiner and Bernd Leno were all signed as well as the young prodigy, Matteo Guendouzi.
Playmaker Kevin de Bruyne and striker Gabriel Jesus were also on the bench following their World Cup exploits with Belgium and Brazil respectively, an ominous warning to the rest of the division of the depth of superstars vying for a place in City's record-breaking squad. Playmaker David Silva could also feature after sitting out at Wembley and goalkeeper Ederson will return.
City made just one signing over the summer as Riyad Mahrez arrived from Leicester, but despite their lack of acquisitions, it would be hard to bet against City being even better in 2018/19.
So it proved. For all the undeniable optimism around the Emirates before kickoff, the first 45 minutes demonstrated that Arsenal have plenty of room for improvement under new boss Emery.
From the moment the 2018-19 Premier League fixture list was released in June, it was clear Arsenal would be starting their campaign with a thoroughly hard test. After utterly dominating the English top flight last season, Pep Guardiola and company will now try and replicate that while focusing their efforts in Europe as well. Benjamin Mendy, a World Cup victor with France will look to keep injuries away as he looks to get a string of games under his belt.
Koscielny, now out with an ankle injury, captained the side in place of Per Mertesacker last season. Emery has spent the most part of the preseason drilling his players and infusing in them his footballing philosophies and ideas to help them become a better team.
With Aubameyang having adapted quickly to life in the Premier League following his January move and given his sparkling form in pre-season there is no reason to think that the Gabonese will not be there or thereabouts this season, should he avoid injury.
Where is the Arsenal vs Manchester City, Premier League fixture being played?
Guardiola's intensity was matched by his managerial counterpart on the sidelines but Arsenal struggled to get close to City on the pitch. "I'm not rigid to stick to one formation or way of playing". Bernard Mendy caused a host of problems down the left-hand side and was involved in City's two goals.
Cech is expected to be handed the armband tomorrow when Manchester City visit the Emirates for the first Arsenal game in 22 years not managed by Arsene Wenger.
