I don't know ... Wenger seems short on inspiration, but I don't think it's any coincidence that we're currently playing with the worst crop of strikers I can recall in all my time as an Arsenal fan since the late 80s.
Someone correct me if I'm wrong and I've forgotten a worse period, but Giroud-Podolski-Walcott-Gervinho-Chamakh, all in middling to lousy form, is absolutely mid table quality, especially (to return to the thread topic) with Walcott half-excluded by contract wrangling.
