This may sound like im a jealous United fan because of their rise to title contenders level recently but i genuienly believe that Arteta is a bang average manager.
He is very lucky to have Edu because almost like Ten Hag, he picks deadwood from his ex club as a copy & paste method of rebuilding his ex club. Zinchenko,Gabriel Jesus & now Sterling.
He is also very lucky to have Pep because he copies & pastes his tactics.
Pep plays almost 4 cbs which allows them to have 3 widely spread CAM &a CEntral cm to provide creativity for Haaland.
Arteta has copied peps back 4, but is playing with inverted forwards so nearly all their creativity has to come from nearly one central area of the pitch with Havertz, Rice & Odegaard which becomes both predictable & also effects their defense if Rice & the cb fullbacks are/is up top as a creative outlet for them.
Honestly, they might scrape a Pl win depending on how much Rodri effects City, but i wouldnt be too surprised if they didnt.
Being set piece specialists can only take you so far, inverted forwards with 4CBs in defense will catch them out. I think Citys creativity trumps Arsenals but we can see when both De Bruyne & Odegaard are back.
