Arsenal haven't been great from what I've seen of todays game. Alexis had a couple of moments where he slotted a killer ball in behind but with Giroud running onto it the move died out somewhat. Not having a dig at Giroud there, just Alexis needs to understand when the throughball is appropriate and when its not. Not sure deploying him on the right is the correct move, I'd like to see him play up top with Giroud especially against the weaker sides. If we get Alexis playing alongside one other forward thinking player with true pace than I think we could be devastating on the counter.
Chambers has looked solid at centreback, Debuchy has looked like a train wreck all game, but its far too soon to judge.
All in all I think today gives us a much better idea of where we are at for the first few games of the season.
I think we're lucky we dont have any big games coming up, we need the German trio (or at least two of them) back and fully fit. Barring no horrible injuries we should be in really good shape for the end of August.
