Arsenal have done well to stick by Arteta. Plenty of opportunities to think of twisting (and many clubs would have).
And I'm 100% sure the tactics and methods Arteta employs now were ever in his wheelhouse and 5 years ago he himself never imagined they'd ever be.
It's a needs must exercise as all his favourite methods were trumped by City, Liverpool etc.
Plus his team in the last couple of seasons is a team born from 4 seasons previous progress......so comparing a teams style/performance/refined personnel against a manager (any manager) that is 30-40 games in, is a bit nonsensical.
Arsenal football club has been great for Arteta. I don't think he's great though, he's not in the excellent/elite manager category imo.
I think Arteta ultimately is their Poch (*ducking* already), in hindsight good, but short of what could/should have been.
If you had asked the Arsenal board if it was ok for them to bet 7+ years & 1.2B+ to be almost there? obviously this year could change that but Emry with that money and time would have delivered something by now.
