Gareth Southgate is the bookmakers' early favourite to replace Sean O'Driscoll as manager of Crawley Town.
The Red Devils are searching for their fourth manager is as many months after O'Driscoll, who had only been appointed as Steve Evans's successor in May, took charge of Nottingham Forest last week.
Southgate, who announced on Friday that he was leaving his role as head of elite development at the FA, is priced at 2-1 with Skybet.
Craig Brewster, Gary Waddock and Steve Coppell have been given early odds of 6-1, 7-1 and 8-1 respectively.
Southgate has had just one previous appointment in football management. He oversaw 150 matches as boss of Middlesbrough between 2006 and 2009.
