We've had some crackers of "applicants" over the last few years, going back to Gus Hiddink when we went with McLeish, then more recently Nobby Solano and now Ravanelli, and I'm sure I'm missing a few.
I think the explanation for these is that their agents just post their CVs to every open post, then fire a message to the relevant newspapers, mainly just to keep their guy's name out there.
