Isn't the lack of goals more of a striker problem? Also, Arteta shouldn't be a starter for next season. Coquelin should be starting games ahead of him. Also, when he doesn't play, he's not the only culprit to slow our play. Ramsey and Wilshere don't drop back enough to provide and outlet when teams are pressing us high. The drift far up field waiting for a pass and won't contribute to the build up at the back. We've had this problem for donkeys and it will only get solved when we have someone that can play box to box and dictate the tempo with their passing. Rosicky has always been the guy that has done this well in the past and Cazorla did a good job last season. It's not as if Arteta is a poor passer or doesn't pass enough. It's when he can't find and outlet that we have problems and that's not helped by Wilshere and Ramsey. It's not as if they can be trusted with the ball either as they turn it over a lot.
It's that core trio Wenger needs to avoid playing together. If he can manage that, we'll do fine in the middle. Also, Giroud standing like a statue in the middle waiting to play a 5 yard pass back to the feet of Wilshere/Ramsey/Ozil etc doesn't help us break down teams either. Keeps us static.
