Derby have a good relationship with Chelsea, who loaned them Mason Mount and Fikayo Tomori last season, and anticipate if negotiations do take place, they will be done so in a relaxed atmosphere.
Juventus are poised to confirm Sarri as their new boss on a three-year deal, with Chelsea having secured a compensation package it is understood could rise as high as £10million.
Club legend Frank Lampard is expected to be named Sarri's successor in which he would work under challenging circumstances with the current transfer ban.
Sarri's Juventus contract is being worked on and is tipped to run for two years, with an option for a further year. There is also a long-standing desire to bring Didier Drogba back to the club in some capacity, while former midfielder Claude Makelele, who quit as manager of Belgian side Eupen on Friday, has also been linked with a return.
Frank Lampard is now the overwhelming favourite to become Chelsea's new permanent manager.
The 40-year-old earned plaudits for taking Derby into the Championship playoffs in his first year as a manager - even if they just missed out on promotion to Aston Villa, for whom former team mate John Terry is part of the coaching staff.
Lampard, though happy at Derby, would find it nearly impossible to turn down a move back to Chelsea. They'll receive more than £5m compensation.
Chelsea legend and Derby County manager Frank Lampard is now the bookies clear favourite to take over the Stamford Bridge hotseat.
But then most clubs aren't Chelsea.
During a playing career in which he won 11 major trophies with Chelsea, Lampard always stood out as a smart cookie. At the same time, Maurizio Sarri will return to Italy after a year in the Premier League.
