It’s nor irrelevant or a red herrjng, quite frankly, it’s intrinsically bound up with the current situation. Fairly criticising the club over those issues you think are irrelevant and repeating them when nothing seems to be done to rectify (or in many cases, got worse) is totally legitimate and justified. Yes, the recruitment over the last few years has been appalling and it’s a major factor but not the only one. This is not a single issue. You sound like someone quite once removed from the reality, to be frank.
I’m surprised you can’t see how these things contribute to reduced gates and income > Owner reduces player budget > gates reduce further > owner reduces budget again, ad infinitum.
