the current performance of the arsenal is much better than many teams, it's even strange that they are having this good performance even if they still have that flaw of theirs for some time being good and for some time being bad, I hope this time it doesn't happen the same thing that happened last season
Form is temporary but with limited resource and inexperienced players to deal with pressure, I think Arsenal will not be able to maintain their performance in a whole season. I mean they will not be able to participate in and complete this season in top 4 of Premier League. They might need a few more seasons to build up his team, stronger and more experienced.
It's not instant, Arsenal is bad in beginning, yes everyone agrees. All critical for Arteta about how he can't get a win versus a weak team. After the deadline, at least Arsenal won and continue until now. Arsenal also has the advantage doesn't have to play on Europa, they only focus on the Premier league only. that possible in the champion zone league for the next time.
From bad beginning, what they achieve so far is impressive and unexpected. Arteta passed through pressure of sack so well and now he is on a right track in Arsenal. However, it takes more time to verify his work because young coach can be beaten and with lack of experience, they might lose their minds and job anytime. It happens with Lampard, Ole already. A good period is not helpful in long run.
