The problem with the attacking midfield in my opinion is not the Arteta-Wilshere axis but the other forward midfield players. When Diaby was having his little surge, hopefully soon to return in reduced games, it was not just his defensive qualities but the fact he went beyond the main strikers on surging runs that made Arsenal so dangerous.
None of our midfield players go beyond the main strikers, to stretch the opponents defence. We play little balls in between defenders for the forwards, especially Walcott, to run on to. In the past we had Pires and Freddy bursting through from midfield and the full backs raiding in their wide positions, sometimes with Thierry Henry wide as well.
Now our players are very static, position wise. This is so we do not leak goals without the defensive cover of someone like Petit and Viera. The problem is that we are too predictable for other teams to defend against.
My conclusion is that yes, Arteta and Wilshere are not the correct players to play where they are, but Wenger has to get these players into the team. Ideally Wilshere would be playing where Cazorla plays, especially as Cazorla has hit the wall, and Arteta would have Diaby with him. We really need another Viera, any suggestions who…?
