I think I can see how this plays out...
SFC: "We've sacked Mark Hughes"
SSN: "Hello, is that David Moyes? We've just found out that Hughes has been sacked at Saints. Would you be interested in taking the job?"
DM: "Well it's the first I've heard of it but yeah, I would be interested in talking to them if they approach me"
SSN headline - "David Moyes interested in SFC managerial vacancy"
Sky bet: "Oh look, loads of idiots have just placed bets on David Moyes to be the next Saints manager. Kerchinnnnggg!"
