Arsenal's got the depth of a team that can't even remember the last time they weren't in the Champions League. They can rest players and still field a strong side. It's about to be strongly tested, but this is the front side of their difficult stretch.
As for the away form worry, I wouldn't put that down as what happened today. Put it this way... We lost by one goal to the second place team at their place. Sturridge "should have" scored three. Agger nearly scored at the end. We also should have had at least one other penalty, probably two.
There are problems, and there are bad days at the office. We came to play, I don't fault our performance.
We can shore up our away form, but it requires defensive solidarity. In this case we're incredibly fortunate that by the time we go to Southampton, probably our most difficult away game left along with Old Trafford, we will probably have Glen Johnson and Lucas back, possibly Sakho and Enrique too, in addition to Agger settling in again.
