If you deconstruct this statement:
BBC sources close to the 37-year-old Shearer, though, say he is extremely unlikely to take the role as he is happy with his pundit work on Match of the Day
it's actually quite clever. One can be quite happy in a job, yet still be happier to move on to something better... And, of course, he's being asked these questions by his current colleagues.
The link won't make any sense in a few hours, but fwiw, Shearer is now 2nd favourite (after Hughes), at only 7/2 (with Hughes 9/4).
