Buy now, think later! hah, but seriously, I believe he could play all along the midfield and out wide on either wing, I could be wrong. I don't know a goddamm thing about either Cazorla or Sahin, but they're new and shiny and I'm an idiot.
Arsenal are looking very congested in the wings and midfield actually. Gervinho, Walcott, Ox, Miyaichi, Podolski could play out wide on the left too. They got options for days in that regard.
But this bit about Podolski and Giroud not being ready for the start of the campaign doesn't really sit well with me, I very much would like to see them play.
Actually, this Cazorla shit isn't even a sure thing yet
