Michael Cox looks at the tactics, Alan Thompson provides the betting lowdown.
Despite their bright start, Arsenal fell behind - Cech failed to cover himself in glory as Sterling opened the scoring a long-range strike that appeared to flash past the unsighted Gunners captain and put City ahead.
Five minutes later Sterling did find the back of the net after beating to defenders before firing the ball into the top corner of the box from the edge of the box, 1-0. After years of Arsenal largely playing the same way regardless of the opposition, Emery's approach at the Emirates will be somewhat more reactive.
Things got worse for Emery when Ainsley Maitland-Niles - only starting at left-back due to injuries to Nacho Monreal and Sead Kolasinac - limped off to be replaced by another newcomer in Stephan Lichtsteiner.
"In general to be at this moment of the season, with the desire to run and run, it was the same last season".
Emery handed debuts to two new signings, including 19-year-old Matteo Guendouzi, a surprise £7m signing from Lorient in the summer. Hector Bellerin, meanwhile, will need all his speed against Leroy Sane.
David Silva could be a question mark for Sunday's fixture as well.
Emery takes charge of his first competitive game as Arsenal boss with Guardiola in the opposing dug out - a coach the former Valencia and Sevilla head coach has failed to beat on 10 occasions. If not, Aubameyang is likely to start from the left flank, although he may the lead the line here. Jurgen Klopp now has new found wealth of midfield options with Fabinho also joining from Monaco, Adam Lallana returning from injury and captain Jordan Henderson getting back to fitness after his exertions at the World Cup with England.
Despite the usual suspects clocking what many would consider routine victories, a poor transfer window for most of the favourites might have handed City the title with Liverpool's acquisitions making them the best placed team to challenge the defending champions.
Manchester City: Ederson 6, Walker 6, Stones 7, Laporte 7, Mendy 6, Silva 8, Fernandinho 7, Gundogan 7, Mahrez 7, Aguero 7, Sterling 8. "We wanted to be professional and we did it". That said though this is still a tricky opener for the Champions.
