Captain is spot on. I look at the team and have the same reaction. It's so average, it's unbelievable.
Szczesny, Flamini, Chambers, Gibbs, Monreal and Oxlade should be playing for mid-table clubs, either because they are average or too young/inconsistent to play for a top team. Then you have Mertesacker, Cazorla, Ramsey, Welbeck who can be very good when they want to be, but has rarely been the case this season.
None of the above guys bar Sanchez, and a form Ramsey are good enough for a title squad.
Wenger fucked up at stage 1, player recruitment. Everything is else bullshit and hot air. He made poor player development choices, and his record in the market hasn't been that good.
