That's the report of the Mirror. The release is likely to cost the Blues a package of around £8m this summer.
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.
On Monday, Sky Sports News reported that Napoli and Chelsea's talks were at a deadlock over Sarri's appointment as Antonio Conte's potential replacement. 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. Chelsea finished a disappointing season in seventh and have missed out on competing in the Champions League next year.
The Italian has been widely tipped to leave Stamford Bridge this summer following a disappointing campaign which saw Chelsea finish fifth in the Premier League, although they did end the season with FA Cup glory.
Numbers were diminished due to several players' involvement in Russian Federation, but those who didn't feature in Russian Federation were put through their paces with fitness and stretching exercises.
Ancelotti is reportedly keen on both Luiz and West Ham's Angelo Ogbonna.
Conte is also holding out for his £9m and intends to work his a year ago of his contract unless he gets it, having not had any concrete offers from other clubs and after turning down Italy's interest in re-appointing him.
