It promises to be an exciting game with City winning all three meetings between the teams last season, including the Carabao Cup final at Wembley, but Arsenal likely to be rejuvenated under new leadership.
"My first message [to the players] is clear", Emery said. A full list of TV coverage from around the world can be found here.
Emery is the first of Arsenal's last six managers, including caretakers, to lose his first league game in charge of the club.
It seemed the goal might open the floodgates, but Cech was in solid form and kept the score down to just one. We have a lot of players with a lack of condition but we are more than two seasons together and know what to do.
For City, it's a lovely start away from home and it shows that even this early in the season, this team is once again the favorite to win the league.
The France worldwide missed most of last season with an injury and Guardiola admitted his return is still a work in progress.
"It was a shame we couldn't finish off our counter attacks and overall we're disappointed with the defeat".
The fans are definitely much more confident for the start of the new campaign and perhaps Emery has given the same boost to the players.
Emery, meanwhile, will know he has much to do, even before a hard derby with Chelsea next weekend.
And, despite just a week of sessions on the practice pitch, City picked up where they left off last term with a confident display that easily put Arsenal to the sword.
"Today is the first step". But in these two moments in the match, we need to work. He departed the club to succeed Wenger at Arsenal with a year remaining on his PSG contract. "We want to give him confidence", stated Emery during his pre-match press conference. Together I think we can improve, to win in our way. This process is normal.
"We spoke at half time about taking more responsibility for the second half, to do a little more".
