Conte is expected to leave Stamford Bridge despite leading the club to the FA Cup title last season.
The 23-year-old was a key player under Sarri's tutelage at former club Empoli, before moving to Juventus at the start of the 2015-16 season after they bought out his co-ownership deal for around £4.5 million.
It now remains to be seen whether Sarri succeeds at what Conte failed to do at Chelsea; convince the board to sign Mertens.
If Sarri is appointed manager at Chelsea, he is keen to target some of his former players, including Senegal worldwide defender Koulibaly. "I'm disappointed that he leaves like this but we have now a big coach (Carlo Ancelotti)".
The Italian head coach will have his work cut out at Chelsea FC after the Blues finished in fifth spot in the Premier League table last term to miss out on Champions League football for the 2017-18 season.
'I hope he [Maurizio Sarri] will win something with Chelsea because he is a nice coach.
There have also been reports that several senior players are unhappy with his demanding training regime.
Golovin has been with CSKA his entire professional career after progressing through their youth ranks and has developed in to one of the best players in Russian football since breaking in to the first team set-up three years ago.
Muddying the waters further is that both Hazard and Courtois have just two years and one year remaining on their contracts respectively and are being strongly linked with moves to Spain.
The Daily Mail is reporting that Sarri is already putting together his Chelsea FC backroom staff despite no official announcement from the west London side about his anticipated appointment.
