Arsenal boss Unai Emery believes their preseason clash with Chelsea won't have any influence on Saturday's showdown.
The two teams faced off in Dublin.
Emery said: “We played two or three weeks ago against Chelsea, but with different players on the pitch, to Saturday - Hazard, Kante, Giroud, Kovacic.
“The personality we want to play with will be the same in this match. It will be different because both teams could have different players on the pitch, but it's a good reference match to work with ahead of this Saturday against Chelsea.
“The first game gives us more information about things to improve and also things to continue doing. It's clear that the result was the first [objective] we wanted. But it was Manchester City's day.
“We need to continue with our work to make the differences in the next match and in the future. For me, what was most important was the players know the positive things we did in this game and also the things we need to improve on and work more for."
