That's the report of the Mirror.
The first-team players will be joined by select members of the loan squad, who will have decisions delayed on their moves with Chelsea wanting to take a closer look at them.
The agreement with Conte is in place and Sarri now expects his appointment on a three-year contract worth around £5.6million a year after tax to be ratified on Monday.
Sarri worked with Rugani at Empoli but the 23-year-old's development has been somewhat stunted at Juve. His poor relationship with many players, furthermore, heightened the likelihood of the Italian being moved along to make way for Maurizio Sarri, who managed Napoli to their record Serie A points total last season.
The long-running saga surrounding Conte has rumbled into Chelsea's pre-season, causing new signings to be delayed as the coach and staff push for their optimum compensation from owner Roman Abramovich, which is for a year's salary and an optional year.
The Brazilian has not played for the club since February after a fall-out with Conte.
Yet Luiz was demoted last term, appearing just 10 times in the Premier League, and the ex-Paris Saint-Germain centre-back is now set to leave the club again.
However, the London Evening Standard says Sarri is the one who has approached Zola about a return to Stamford Bridge and not a member of the club's hierarchy.
