I'm not completely up to date in this thread, but Blanc makes too much sense for Arsenal?
Not saying Arteta might not work, but that is a huge gamble. Not sure why it is necessary to take it when you got good alternatives available. And for Blanc why wouldn't he want it? I agree it is tricky to take over from managers that have been at a club for a long period of time, but as others have mentioned this is not Ferguson leaving with a PL title. If anything I expect Arsenal to bounce back a bit next season regardless of what they do in the summer and who they hire. Arsenal haven't got a fantastic squad, but right now I think it is underperforming. So if I were Blanc I wouldn't be too worried about taking over from Wenger.
