If Arsenal were consistent until the end of the season maybe they could win the league last season, but unfortunately Manchester City is more consistent than them, that's why Manchester City deserved to win the league last season by bringing a treble winner, this season Arsenal certainly want to chase that win. league this season but I think they have to improve their players to be able to maintain their stamina and be consistent until the end of the season.
There is a lot that needs to be fixed from Arsenal and Arteta has to make it better, it's not easy to win the league of course there is a lot of hard work for that, like Manchester City often failed and finally managed to win the UCL last season they were really consistent so they could get a treble winner, Arsenal had to learned a lot by manchester city
there will only be one representative from the premier league to be the team that will enter the final round. I mean even though Arsenal will work hard and Arteta will try to find the best strategy and maintain the stability of his players it will be a little difficult against Man City. because for now it looks like Man City will take the lead to continue to the champions league final with the same formation and performance as last season as we can see there are no major changes to Man City's formation such as only recruiting new players in small numbers.
on the one hand we have to think realistically that no matter how strong Arsenal are, they cannot match Real Madrid's performance. so it will be a very hard job for Arsenal if they really want to get into the finals of the champions league.
