I don't think this system of Wenger to play only one or no wide players is going to win us much.
I also think Carzorla is at risk of burning out. He was a non factor last night.
With Diaby out and Wilshire back we have become too small of a team in midfield again. IMO we lost the midfield battle on physicality. We should look for tall physical holding midfield player.
It is starting to look more and more likely we will not qualify for the CL. I don't think there are any quick fixes for this team. Even a big midfield player will possibly need more than half a season to integrate effectively into the team.
I hope if we don't qualify for CL football that our home games will be half empty. The owner doesn't deserve more IMO.
