Empoli president Fabrizio Corsi is convinced Maurizio Sarri will be a big hit with Chelsea.
Sarri left Empoli for Napoli three years ago and is now regarded as favourite to succeed Antonio Conte as Chelsea manager.
Corsi said: "Will he go to Chelsea? If he deserves it.
"I think that in London he can do even better than he did with Napoli."
Chelsea failed to trigger the €8m buyout clause before the May 31 deadline, leaving Sarri to take Napoli to court to secure a release from his contract.
