Arsenal's two seasons of failure indicate that they still want to continue competing at the top of the Premier League, as long as Mikel Arteta is still trusted by Management, of course Arsenal and Arteta want changes next season because it is very likely that Arsenal already knows what Arsenal needs next season, right? Only the title, however, is Arteta's main target to take Arsenal to the Champions League Final, which Arsenal have never experienced before.
Since Mikel Arteta became Arsenal coach, many changes have occurred and the progress of the team's performance has continued in a positive direction in the last 2 seasons, even though they did not win the title, their performance continues to improve, so it is also possible that this will continue to happen next season.
I also think the same, if as long as Mikel Arteta is Arsenal coach it will be possible for them to continue to do their best and continue to try to win the title.
And what you also have to remember is that winning the Premier League is not an easy thing, this is the most competitive competition so everything takes time and is a long process and Mikel Arteta is going through that.
