I don't think the bookies have a clue or even care, as they make money on this whatever the outcome. Kevin Nolan wasn't in the running last time until the very last minute. I expect someone to emerge shortly before the announcement and at that point, they'll be odds on and not worth the punt.
Ainsworth?
Interesting times at Notts, with Kewell all but confirmed and a slew of new players looking to join him (up to 4 or 5 according to Charlie Slater) the current odds make interesting reading, *IF* you're optimistic!
Top prices both at BetVictor,
Promotion 8/1
Top 3 Finish 12/1
How the market will react short term depends on the calibre of the signings, and of course the result on Saturday.
