You have to feel sorry for the lad that he picked up an other long term injury. In the short term I don't think this has to be all that bad for Arsenal sine it prevents Wenger playing Arteta and Wilshire at the same time, a combination I was not a great fan of and not only because of the lack of pace it introduced to our game.
I is possible this forces his hand to play Ox a little more often in the middle and Narby out wide. I think we do better with a little more pace in the squad and Ox has been playing with conviction.
Of course this thins our squad out even further but I don't think this injury, given Wilshire's indifferent form, will be as devastating to our season as Ramsey and Walcott's injuries have been.
And who knows maybe the new Swede, Kallstrom, will pleasantly surprise us, he is supposedly near ready to play.
