I mean it's still City and Pep's juggernaut they're competing with. As long as Pep is around, I don't personally think there is any pressure on Arteta to win the title. He's playing with house money in that regard, because if wins the title vs Pep, the credit and acclaim he gets will cement him as one of the best in the world (which he kinda already is imo, but he doesn't have the trophies to back it up), and if he finishes 2nd again, well it's Pep and City innit.
He does probably need to start doing better in the domestic cups though.
