It would be extraordinary if Arsenal could beat Manchester City when they visit the Etihad Stadium at the end of this month, but I don't think that Manchester City will immediately lose when they host Arsenal at the end of the month unless many of Manchester City's key players are injured. Because as long as there are still many key players from Manchester City who are fit enough to play, it will be quite difficult for Arsenal to beat Manchester City at the Etihad Stadium.
If they want to become champions, Arsenal must be able to beat Man City even though the match will be said to be much more difficult, especially since the match will be held at the Etihad stadium so the pressure on Arsenal will be much greater. When playing at home to Arsenal, Man City had to admit a narrow defeat and Arsenal's victory was not easy because it was only in the 86th minute that Martinelli managed to score a goal and at that time Man City was not reinforced by a creative midfielder so they had difficulty scoring goals.
Now Man City is much more favored because a number of core players can play so the attacks will be much more dangerous. Arteta must have a way to stop Man City's attack because if they are unable to stop it, Man City will stop Arsenal's dream of becoming champions like last season. If Arsenal loses then Liverpool will benefit more because they will again lead the standings.
