Apart from the primary reason we are all here in the first place. Competitive sport. And if that's not their primary reason then they should all fuck off and go into hedge fund management. The fans' expectations are aligned with the purpose of the sport, the board's and the manager's aren't. If the promise had been austerity in return for a big new stadium and eternal 4th place so Stan could mortgage himself to the hilt and Wenger could have a job for life then only Ty and Chris Wenger and the Mysterious Four would have been up for that. Everyone else would have said fuck off.
Wenger is certainly fulfilling the ambitions of the board, no doubt about that. But what's that got to do with Arsenal Football Club? Nothing.
The question is, what do this lot achieve in terms of the intended purpose of this club? Answer is, nothing of relevance. It's a basic requirement to make sure the place doesn't go bankrupt. You don't get prizes and plaudits for not bankrupting the place, or at least you shouldn't. This lot have turned the bare minimum into the height of achievement and they are so delusional they boast about it.
Well, in terms of why we are all supposed to be here, they are the biggest losers in the game. The fact they can't see it doesn't change the reality.
