Speaking to some Arsenal fans, they're going to use this game to bring back some of their players returning from injury who need match fitness like Walcott, Fabregas and Bendtner.
I really don't see the harm of playing a full-strength team - they need to practice playing well at home. If injuries are going to happen this season, they'll happen - no sense wrapping players up in cotton wool. It's not like we're playing five games a week, and it's not exactly Stoke/Wolves we're facing here either. Just my two cents.
