Maybe, but we weren't saying he was obviously just rusty until he'd actually put in a decent performance. For all we knew he was just young, green and not adapted to the league.
Absolutely true we should've had a clearer answer to that question sooner, though. The more I think about it, the more I tend to conclude that Arteta gets both the credit for the great achievements of this team this season, and the criticism for these little failures in the margins of his approach as well.
