Making it difficult to reply with that much in a post...
It WAS 100% men against boys . Arsenal defended better, attacked better(clinical in front of goal converting more goals with less chances), and were clearly drilled better all over the pitch. They key here is that stats betray this game, all the "oh but we COULD(aka didn't) have defended that bit better" etc is pretty irrelevant. The point is arsenal didn't over extend anywhere on the pitch, stuck to a game plan, executed it well...and city didn't.
Yes, piss poor or the rest of the game. Even when you claim yaya was running riot, it only seemed that way because the rest of the team were literally all over the shop in the last 20 minutes running like headless chickens meaning yaya managed to find space...as i said previously if arsenal were on point this evening on the break, then that scoreline would have ended more like 4/5-0 by the end.
The fact that arsenal were average, and you yourself claim this, only serves to prove my point. It sucks but thats football sometimes, sack the manager, offload the deadweight asap and sign a CM, ST, and CB in january. Perhaps a temp manager will be enough without all the signings until the summer.
Surgery is needed now though in some form.
