If Robin leaves we'd need another attacker, but not necessarily a striker.
Add Carzola to Podoski, Giroud, Gervinho, Walcott, Chamberlain, Rosicky and a couple of starlets providing a bit of support and I'd reckon we'd be ok in the forward department.
The two deeper midfielders still worry me though. Song and Arteta are good but there is a real lack of depth. Jack's fitness is obviously a concern and with Diaby you wonder if he's even good enough, same with Frimpong.
With that in mind, I'd like Carzola and a more defensive minded midfielder.
