As opposed to last year they actually signed very good players in positions of need. It's another matter they needed at least twice as many but they're incompetent.
I was very wrong on Arteta. The way media talked about him before he came to Arsenal was this Pep prodigy and I thought he was another hipster coach.
So far he's turned out to be as pragmatic as they come, recognized their weaknesses, tightened the defense, won immediately and showed strong character in pushing the board and demanding ambition from them.
