No other visible candidates and Del Bosque is leaving after the Euro. Big chance he'll get the offer. I agree that he doesn't seem to fit the international manager mold, though. I don't think it would work.
There's also Valencia, but I don't see him getting along with their current ownership (granted, he's got Ashley to contend with at NUFC). And it seems he wants to stay in the UK for the foreseeable future.
