Jon Brady, who is in temporary charge, has been installed as the early favourite with the bookies, but there are many names in the frame. Let's take a closer look at the runners and riders....
9. Sol Campbell
Age: 46. Current status: Unemployed. Previous jobs: Macclesfield, Southend. Odds: 7/2. Summary: Kept Macclesfield in L1 against the odds but struggled at Southend and is unpopular with Cobblers supporters.
10. Paul Tisdale
Age: 48. Current status: Unemployed. Previous jobs: Exeter, MK Dons, Bristol Rovers. Odds: 10/1. Summary: Won promotions with MK Dons and Exeter but sacked by Rovers only last week after a miserable three months.
11. Gary Caldwell
Age: 38. Current status: Unemployed. Previous jobs: Wigan, Chesterfield, Partick Thistle. Odds: 10/1. Summary: Won promotion with Wigan but didn't last long at either Chesterfield or Partick Thistle after struggling at both clubs.
12. Luke Garrard
Age: 35. Current status: Boreham Wood manager. Previous jobs: None. Odds: N/A. Summary: Another left-field option but he's well-regarded in non-league circles for the work he's done at Boreham Wood.
