Hope Rosicky isn't! He's finally putting a good run of games together for the first time since 2000. Lets not mess with that and keep playing him until he gets injured. Ramsey won't have to wait too long.
And before Arteta and Ramsey walk back in the team, I wouldn't mind trying that Oxlade in midfield experiment again. It allows him to sit back in midfield and spot who the weak link in defence is, and then he can go running at them. Last time Mesbah. This time it could be Collocini or summat.
