The Everton boss is under huge pressure after a woeful season to date.
Alex Donohue of Ladbrokes said in a press release: "It was always looking likely Martinez would move on this summer but the derby result has shortened the odds of an even swifter exit. As far as a replacement is concerned Moyes is still the front runner although Pellegrini is also proving a popular bet."
Next Permanent Everton manager
David Moyes 4/1
Marcelo Bielsa 6/1
Manuel Pellegrini 10/1
Roberto Mancini 12/1
Eddie Howe 12/1
Roberto Martinez to leave before FA Cup semi-final 3/1
Roberto Martinez to leave before start of next season 1/6
Even Martinez himself couldn't hide from last night's 4-0 defeat to Liverpool with his usual flowery language.
Normally, a poor performance has been followed by phrases like 'we have the potential for something very special.'
But the Spaniard knows his position is fast becoming untenable at this rate. Not only is he under threat from a new owner who might actually want to win something with the Toffees... the Everton boss's performance is at a level that'd get him sacked at most clubs.
