I think Arteta gained significant experience from last year and will warn his players about this. Manchester City were lucky because last year Arsenal have been losing in the league with huge inconsistencies lately. I don't think we will follow the same scenario this year. If Arsenal takes the lead this year, they will continue to develop various tactics with Arteta to use this advantage.
Maybe the problem is whether Arsenal can continue to be consistent throughout the season? we often find that Arsenal always leads the top of the standings at the beginning of the competition to the middle, but they are always destroyed when the competition is about to end. I think Arsenal's job remains the same, namely to continue to improve the consistency that so far they have not been able to completely fix.
Meanwhile, Manchester City can sometimes do two things, they excel from the start of the season to the end of the season and sometimes even though they have slipped in the middle of the season they are able to correct mistakes to close the competition with a title that is their pride.
