Chelsea are set to announce the departure of manager Antonio Conte after two years in charge.
The club have refused to comment on the status of the 48-year-old, who won the Premier League title in his first season and the FA Cup in May.
Conte took pre-season training this week but his future has been a source of contention and ex-Napoli manager Maurizio Sarri expected to take over.
The Blues have reportedly agreed on a compensation package for Sarri, 59, reports BBC.
Should Sarri be appointed, he would be Chelsea's ninth full-time manager since Roman Abramovich bought the club in 2003.
During three years with Napoli, Sarri has not won a major honour but has guided the club to finishes of second, third and second again - behind Juventus in 2017-18. The former Empoli manager was named Serie A Coach of the Year in 2016-17.
