'Academic' debate is all we do on here
I do understand where we are - and that is a good part of my concern about where we can get to under Arteta. I think that we have set ourselves up - both in terms of our system and our players - not to be able to adapt to the more efficient and effective way in which many of our competitors are playing the game. I agree with you that swapping existing players will not achieve this. More generally, we have too few creative players; to few runners to receive the ball in advanced positions; and no reliable finishers.
We have spent on players and have a high wage bill. The quality we do have has been enough for us to finish second with a following wind. But our system is now too easily neutralised - even with all our forwards available. And even the potential transfer targets we have been linked to are unlikely, IMO to see us champions.
