Manchester City will definitely be ahead in this match considering the statistics against Arsenal but the performance of the match may be different. Arsenal have packed their squad very nicely since last season but Manchester City are yet to pack up their squad like last season as they have already left their club with a number of players who have yet to find replacements, maybe against Arsenal.
It is difficult to predict this match. Because here the two teams are very strong. There is no way to call any team weak. But as you said, Manchester City is under a bit of pressure now. There have been several changes within their team. Because of this, Manchester City's performance is somewhat unstable. One of City's most important midfielders, İlkay Gündoğan, has left the team. And Manchester City is yet to find a suitable replacement for İlkay Gündoğan. On the other hand, the Arsenal team is still in a stable position. They impressed everyone with their excellent performance against Barcelona.
This match will be a bit difficult for Manchester City. Some players have left Manchester City but maximum players are still fit which is very good news for Manchester City. Manchester City will definitely field their best XI against Arsenal and they will definitely be thinking of winning against Arsenal.
Manchester City will play for the purpose of winning against Arsenal. At the same time, City's performance against Arsenal has been very good. Manchester City have won all of their last 5 meetings against Arsenal. In these 5 matches, City scored 15 goals and conceded only 3 goals. Considering the statistics, Manchester City can be considered as favourites.
