Actually that is not the same team that tie with city. They missing Gibbs, Diaby and Gervino.
The fellas on FSN make a comment that I could agree with, Arsenal squad could beat anybody. The team that sweating now? not so much.
The thing that must frustrate Wenger (though a lot if it is his own doing) is that he seemed to have cover for every position at the start of the season and was looking forward to the return of players like Wilshere, Sagna and Rosicky to strengthen the squad. Now he in the same position as last season, Podolski, Cazorla are a little stale, Ramsay is a good player that doesn't add anything to the team in his current position, and he has no one on the bench to be able to change things up. And look now, Ramsay injured too.
This is an opportunity for Arshavin to make his way back into the picture. I can't see any good replacement for Santos, so he plays until Gibbs is back.
Arsenal's biggest problem might be the medical staff/training regimen. Every season there are multiple players out, often in the same position, or a position where they are thin.
I expect as they get players back and/or get knocked out of competitions, they will improve considerably.
