I'm not sure I see any of this as a "problem" except in terms of the special entertainment factor of that earlier, more innocent era.
We've scored bags of goals and achieved good results in historical terms under Arteta, despite the lack of major trophies.
Football is being played this way mostly because it's what has been working. We also beat Ancelotti's Madrid badly enough he got sacked, and that's despite the amazing quality he had at his disposal.
Yes it'd be nice at times if "player intelligence" had more of a role, but also we spent years complaining about Wenger's methods in which half-field short-sided scratch matches brought out a peak of intuitive mutual understanding and creativity, but a lot less tactical discipline.
End of the day we have done the work and modernised the club under Arteta and now it's up to the entire hierarchy to deliver the major trophies. Now.
