@[deleted] Our problem?
The ideology of the board and owners, in which Wenger is a willing and complicit collaborator, is our biggest problem.
The inadequate money being spent is the next biggest, and it's an inescapable consequence of that ideology.
The quality of the players is the next biggest, and it's an inescapable consequence of our spending. We can't sign top talent, and we shed our best players because we don't spend on wages in line with our rivals.
The nature of the football we have to play in order to get the best out of the quality of the players we've got is the only problem we can alleviate in the short term. If you assume correctly that Wenger isn't going to be sacked, that's where this thread has its focus.
In previous seasons you probably would have said that taking the players available as a given, Wenger did well with what he had. This season, it seems we're even getting less than we should be out of what we've got.
