Former Sunderland managers David Moyes and Sam Allardyce are among the contenders to replace Ronald Koeman at Everton.
Everton have sacked Koeman following their 5-2 defeat to Arsenal on Sunday after just 16 months in charge.
Bookmakers BoyleSports have made the Toffees Under-23 manager, David Unsworth the early 5/2 favourite to replace Koeman with former Black Cats boss David Moyes 4/1 second favourite to return as the gaffer at Goodison Park, having left the club in 2013 to take over as Manchester United manager.
Burnley’s Sean Dyche, who was also tipped for the Leicester managerial position, is also in the mix at 13/2.
Other names in the running include, Carlo Ancelotti, former England boss Sam Allardyce, both 10/1, Welsh manager Chris Coleman (12/1) and Bournemouth’s Eddie Howe (14/1).
Aoife Heffron, Spokeswoman for BoyleSports said: "David Unsworth is already set to take the reins temporarily after Ronald Koeman was shown the door, but at 5/2 it looks like Unsworth could be there to stay as a permanent manager.
"David Moyes is of course high up the manager rankings as a replacement and at 4/1 for Moyes to return, it is already a two horse race for the role."
