Well, it looks good on paper, but...
Right flank is inexperienced, Sagna is not natural LB, Cazorla is out of form, Podolski is coming back from 4 month injury and I don't think he will play full match, Bendtner is just Bendtner and I think Arteta is out of form, last few matches from him were not very good.
However, some players are just doubtful, this is from Arsenalyouth site:
In addition, Thomas Vermaelen and Nacho Monreal could miss out through illness, whilst Theo Walcott and Tomas Rosicky are also doubtful. Vermaelen and Walcott did, however, make it through the training session unscathed, suggesting that they could be involved in some capacity tomorrow.
