I think we'll see the same team line as per last weekend with the only change being Podolski at CF with Walcott to come in at RWF and because of our two previous clean sheets, Kos will start on the bench.
My line-up would be:
GK - whoever is fit
Jenkinson - Per - TV - Gibbs
Arteta - Ramsey - Diaby
Walcott - Giroud - Carzola
Defensively, I thought we have been good in the last two games. Mertesacker defended well from set pieces and while I think Kos is our best defender, I see no reason to rush him back into the team just yet.
In midfield, I would have preferred having a viable alternative to Diaby to play alongside Arteta, but Wenger for some reason just doesn't believe Coquelin is ready. Ramsey for me hasn't done badly so far and I want to try Carzola further forward as our front three have had trouble gelling. If Ramsey is struggling, we can drop Carzola back into midfield.
Up front Gervinho didn't do enough last week to justify starting this time round. I think Carzola will be a better link man than either him or Podolski, who did play well last week, but without really troubling the Stoke defence. However I don't think he is good enough yet to play as a CF in our system and my initial impression is that it will take a lot longer for Giroud and Podolski to build up an effective understanding as they didn't really show any in the last game. As for Walcott, I would quite happily bench him in favour of Chamberlain, but I think we need one or the other to start.
