It comes after reports Jose Mourinho could make a shock return to Chelsea for a third spell in charge - and after Rio Ferdinand described his former England team-mate Frank Lampard as "the ideal choice" for the Blues job.
Chelsea legend Frank Lampard is the clear favorite at 8/11 (-137) with Paddy Power to succeed Sarri after impressing in his first managerial role at Derby last season, where he guided them to the Championship play-off final, only to lose to Aston Villa.
"He is the flawless choice".
Former Chelsea manager in consideration to replace Maurizio Sarri at Stamford Bridge, as hierarchy at Chelsea looking for a replacement.
But he will soon be forced to look at alternatives with just 18 days to go before the 2005 Champions League-winning chief can leave. He and [Derby assistant manager and former Chelsea youth coach] Jody [Morris] know all the kids from 16 upwards. People talk about experience but what experience did Pep [Guardiola] have when he went into [the] Barcelona first team? "Frank knows the club and the players will respect him".
Any agreement for the 60-year-old to head back to Italy will then prompt an official approach from Chelsea to Derby for permission to speak to Lampard about becoming Roman Abramovich's 12th manager in 16 years.
The Blues manager is expected to be appointed as Massimiliano Allegri's successor at the Turin club and claims suggest the Brazil-born Italy global could follow his coach.
"Are they going to continue doing that? At a time when managers are scared and under pressure not to play kids I think it will be refreshing".
