We don't and can't know what players we really need or if we in fact need a new squad, which is very unlikely. A new manager will have to figure that out. I don't blame the players. I mean I'll blame them if they fuck up on a match to match basis or if they are habitual under-performing fucks like Theo Walcott. But in terms of the tragic mediocrity we are trapped in and the lack of a backbone when it come to the fight, that's all Wenger and the culture he has built.
It can't be the case every player through the doors over the last 10 years has been weak or unambitious. It can't be the case we haven't stumbled on a single leader in all that time. The environment at Arsenal breeds complacency and arrogance and entitlement. Wenger insists on having control of everything so this is his team, his complacency, his arrogance, his lack of ambition and it flows down through the players and out to half the fan base. This is where the 4th place trophy comes from, Wenger's divided and inverted priorities. Please the board, please the players, please the fans, please the media. Yes, it's bloody tough. But the best way to do the job is to compete hard and win, then by one means or another everyone ends up happy. Pleasing the board while reaching the minimum benchmark everywhere else is a losing policy, the opposite of what's required. That's Wenger's choice and he has to live by (though apparently not fall by) his choice.
