I mean we were also very bad before Arteta arrived, so that should be kept in mind. He hasn't made us a terrible attacking team, he just hasn't fixed it either.
Yeah that’s my big worry. Like @GDeep™ said, he has made us better defensively but that’s mainly through getting numbers behind the ball and adding a bit of structure. Managers like Pulis and Allardyce could’ve done that. The attacking play hasn’t progressed at all. We have scored some pretty goals playing out from the back to front but we did that under Emery as well. What we’re seeing outside of those goals is the same as what we saw under Emery, that being we dominate possession and focus attacks down the wings with very little to show for it.
