Bookmakers have seen support for Jose Mourinho to be installed as Chelsea's next manager following speculation that Rafael Benitez could be sacked by the Blues.
Benitez at the weekend insisted he would not be sacked as Chelsea's interim manager following the Blues' 3-2 defeat to Newcastle on Saturday.
Moussa Sissoko scored twice on his home debut as Newcastle came from behind to beat the European champions, and the result led to bookmakers on Saturday night suspending betting on Benitez being the next Premiership boss to be sacked.
A defiant Benitez told reporters that his job was not on the line, despite increased speculation that he could be axed before his contract expires at the end of the season.
"If the players show the character that they showed in the second half, it means something is right," Benitez said at the weekend.
"If we cannot control these games, it is something we have to improve. With some players: David Luiz, [Eden] Hazard, [John] Obi Mikel and Victor Moses coming back that gives us more options and maybe we can have fresh legs on the pitch.
"When we are in form and doing well, we can beat anyone. We are doing a good job in terms of what you can see on the pitch so we're doing well. The team has great team spirit and I'm confident that the team will finish in the top three."
Reports in Monday's newspapers suggested Benitez could be fired in the coming days, however, and bookmakers William Hill on Tuesday afternoon made the former Liverpool manager 6/5 favourite in their Premier League sack race market.
Hill's make Real Madrid coach - and former Chelsea manager - Mourinho just 5/2 to be in charge at Stamford Bridge next season in their Next Chelsea Manager market and William Hill spokesman Rupert Adams told Crunchsports.com: "Mourinho is the big mover in the market to be the Chelsea manager and is now 5/2 having been as big as 33/1 just a couple of months ago!"
