If Arsenal again fails to meet expectations in the Premier League and Champions League next season, in my opinion Arteta deserves to be fired, and Arsenal must have the courage to spend more money to appoint a more experienced coach. Arteta main priority is to end the Premier League title drought which has lasted for two decades, the Champions League trophy is still too difficult for them. The existence of Manchester City makes it difficult for Arsenal dreams to be realized at the domestic level, especially in the Champions League which has more elite teams. However, what Arteta has done in the last two seasons deserves appreciation, he has succeeded in managing Arsenal to get better every season. We realize that Arsenal has all the attributes needed to achieve success, but the front line of Arteta squad still needs to be improved.
Arsenal are not easy to let go of the coach because after all, seeing from Arsene Wenger's condition before the Arteta era, even Arsenal's performance was below Arsenal's performance now but Arsenal continued the contract with Arsene Wenger until he really left and did not train anymore.
This will also be the same, Arsenal is a great club but as long as in the EPL there is Manchester City and Pep then they can't do anything and sacking Arteta could also eventually be the wrong decision where it could make Arsenal's performance return to form and return to not being like a big club because the transition and performance is very bad.
Especially when talking about the Champions League where a lot of clubs are actually much better in terms of experience so expect Arsenal to win in this competition and when they fail to sack Arteta then it could be that next season they become more chaotic than at this time which is indeed the end of the season always not going well for them.
