Emery has overseen a number of departures since taking over from Arsene Wenger, including long-serving midfielders Jack Wilshere and Santi Cazorla.
Emery's ultimate goal is to win the Premier League, but he wants to see his players do it in style.
The coach said he expected midfielder Ainsley Maitland-Niles to start in that position against City, although there was a small chance that Monreal would be ready. The representation for every player and in every time in the season the capacity to do that. But in these two moments in the match we need to work.
Arsenal finished sixth in the Premier League last season and two-time Premier League champions Nwankwo Kanu recently declared that it would take a "miracle" for the Gunners to immediately challenge for the tile this season.More news: China's July exports rise more than expected despite U.S. tariffs

Arsenal boss Unai Emery has rubbished reports linking Mohamed Elneny with an Arsenal exit this summer, confirming the player's stay at the club. I like playing him because the preparation is demanding, to try and beat his teams and when we were in Spain, every match against Barcelona for Valencia and Sevilla was very exciting. To say it here is easier than doing it on the pitch.
"Today, we had a meeting with the players to close all the possibilities to bring more players". For that, we are working this week and preparing for this game and preparing for the opposition against City as a collective and as individual players.
"The match is going to give us the information [of what] is our level", he said.
Arsenal boss Unai Emery has chose to stick with Petr Cech as his first-choice goalkeeper despite the summer arrival of rival shot-stopper Bernd Leno, according to reports.
"For me, it's positive and his commitment is for me, to Arsenal, the most important".
