In the absence of injured defender and skipper Laurent Koscielny, Emery has picked out four more "leaders" among his squad - and Cech is one of those. I repeat: "organised, then play".
Speaking to Wolves TV, Dendoncker said of his new employers: "I followed them a little bit past year and I saw they did really good".
Arsenal's first team left backs aren't available, Sead Kolasinac is now injured and Nacho Monreal just returned to training so he isn't ready for the match against Pep Guardiola's men and the manager has hint that Ainsley Maitland-Niles could be chosen in that position on Sunday.
Emery explained his reasoning at his pre-match press conference ahead Sunday's game, saying: 'In my career, I want leaders in the team.
Opening games against City and Chelsea will provide a flawless test for Emery and his team who will be desperate to improve on last season's sixth-place finish. "Today, we had a meeting with the players to close all the possibilities to bring more players", said Emery.
Emery also announced his choices as club captains.
Instead, Emery must focus on getting the best out of Gabon striker Pierre-Emerick Aubameyang, who made a fine start with Arsenal following his January move from Dortmund, while also finding a way to dovetail the creative talents of Mesut Ozil and Henrikh Mkhitaryan.
"I want one thing, because it's very important for us and for the player, is take confidence".
"I met the Kroenke family in Atlanta and he gave us his commitment in this project with Arsenal", added Emery.
"When we are thinking in an attacking moment, I want the goalkeeper thinking for that, he is the first".
Emery could not have been handed a more hard start to life at Arsenal with a trip to Chelsea following on from the visit of City.
"We are excited", he said.
The former Paris Saint-Germain and Sevilla boss faces a baptism of fire by hosting defending champions Manchester City on Sunday, then enduring another tough test the following week with a trip across London to Chelsea. "But we want to play with the idea to create a winning mentality".
