You are deluded if you don't think that the longer this s*** drags on the more likely it is that Carber will get it.
If Ashley wanted him then he would be in by now. Ashley doesn't care what we think, he does what he wants. He gots plenty of stick but still does what he wants, from hiring Pardew almost instantly, to Sports Direct adverts, selling popular players, and even having Wonga as our main sponsor. If Ashkey wanted Carver in the job then he wouldn't wait in order to let things settle down, he'd just appoint him. See the appointments of Pardew and re-appointment of Kinnear at the club.
The fact is that so far there has been no appointment of Carver and all reports indicate that Carr will be having an input in who to bring in as a manager with plenty of suitable names mentioned. Even the article that says Carver maybe in charge for the Southampton match indicates an outside appointment.
He's probably too busy stuffing his face in the Caribbean to make any decision right now.
