"I think they deserved this result, but we were improving during the 90 minutes like I think we need for next week and the next match", Emery said at a news conference.
Guardiola said it was too early to tell if his players had the same hunger as last season to hold off challenges from Manchester United, Liverpool, Tottenham Hotspur and Chelsea, who all won their opening fixtures.
They embarrassed us badly a couple of times last season and they themselves will be feeling very confident as they begin the defence of their title.
Arsenal's Henrikh Mkhitaryan kicks the ball between Manchester City's Raheem Sterling, left and Manchester City's Bernardo Silva during the English Premier League soccer match between Arsenal and Manchester City at the Emirates stadium in London, England, Sunday, Aug. 12, 2018.
"When we are thinking in an attacking moment, I want the goalkeeper thinking for that, he is the first".
New Arsenal goalkeeper, Bernd Leno could get the nod over Petr Cech for Arsenal's opener against Manchester City. We have a lot of players with a lack of condition but we are more than two seasons together and know what to do.
Sterling proved to be City's creative fulcrum, but he was fortunate to escape with a yellow card for a studs-up foul on Arsenal debutant Matteo Guendouzi in the early stages.
I will be using half my stake backing Over 3.5 goals before the game starts at around [2.5] and also placing the other half on Over 2.5 goals with a keep bet should it reach [2.0] in running. He's working very well. "He played also good in the preseason, but he can wait for his moment to arrive". Injuries to Sead Kolasinac and Nacho Monreal had forced Emery to call on Ainsley Maitland-Niles at left-back, and the youngster, a natural midfielder, struggled badly against Riyad Mahrez and the overlapping Kyle Walker as City pinned the home side back in their own territory.
It doesn't get much easier for Arsenal as they travel to Stamford Bridge next Saturday, while City play host to Huddersfield the following day.
Ainsley Maitland-Niles came on for Kolasinac after he was hurt in Arsenal's 1-1 draw with Chelsea on August 1 and Emery said following the match he would not rule out using the 20-year-old against City.
