Arsenal is not a club that often changes coaches, after the Arsene Wenger era ended from 1996 to 2018, now Arteta has managed to maintain Arsenal performance even though they always lose in the EPL title race. In my opinion, Arsenal only weakness lies in the mentality of the players, Arteta needs to improve the mentality and strength of the team to maintain the opportunity to win trophies that they have always failed to win.
If Arteta can do it, maybe he will be the next Arsene Wenger at Arsenal.
There's no way to compare Arsene Wenger and Mikel Arteta.
From the first 5 years they joined Arsenal, Wenger won Premier League 2 times and other 4 small cups, while Arteta only won 3 small cups. Arsenal have to fire Arteta, if Liverpool were fine with Klopp, now they're better with Arne Slot.
There are still few high quality managers aside from Arteta.
But does firing Arteta guarantee that they will get the title they want? Of course not, and maybe something worse will happen. It should also be remembered that the coach must go through an adaptation process and if that fails it will be bad for the team. All decisions are in the middle of management, but I think Arteta's performance is also closer to what they want. As long as he continues to be consistent, then sooner or later he will definitely be able to bring this team to win the title. In the last few seasons he has always been able to compete even though he failed to become a champion in the end.,
