We've got a proven goalscorer that we can't get the ball to as it though. I really don't see what difference another 9 would make in this side. We could sign one and within a month people would be complaining that he's crap. This system is designed for forwards to fail.
The system doesn't suit Auba, which let me be clear, is Arteta's fault. We don't play the ball early into space for him, it's slow build up that puts an emphasis on him playing with his back to goal a lot, not his game.
But surley Arteta knows this? If he's so hell bent on this style of football, you'd think to give even himself the best chance of success, he'd bring in a player that could do the things he wants a CF to do? I don't get it.
