Jorginho undergoes Chelsea medical as Napoli move to block Maurizio Sarri transfer raid

Napoli chief Aurelio De Laurentiis is keen to ensure Maurizio Sarri does not take any more of the Serie A club’s players with him to Chelsea, with midfielder Jorginho due to undergo a medical on Thursday.

Chelsea have agreed a fee worth up to £57.4million for Jorginho, which is believed to include a compensation payment for Sarri, but Napoli president De Laurentiis will not let the move go ahead until he has assurances none of the club’s other top talent will move to Stamford Bridge while Sarri is there.

His demands should not hold up Sarri’s arrival much longer but Napoli lawyer Mattia Grassani said: “There was a meeting in Rome at the offices of De Laurentiis, without Sarri. We exchanged views with the English club and the coach’s lawyers.

“De Laurentiis wants to leave nothing to chance for the time Sarri will be at Chelsea. These are dynamics we have been facing and should be concluded by the end of the week.”

Chelsea will have to also come to an agreement to pay off current coach Antonio Conte, who has taken the pre-season training since Monday.

Jorginho has already agreed a five-year contract worth up to £102,000 a week.
