After a protracted move from Napoli to Chelsea - in which time Maurizio Sarri was left in a form of managerial purgatory - the Italian has finally taken the reins at Stamford Bridge and has wasted little time in revolutionising the club's playing staff.
On the same day that Sarri replaced Antonio Conte, Napoli midfielder Jorginho was reunited with his former boss in a £50 million deal, signing a five-year contract.
The 26-year-old joins World Cup winner N'Golo Kante, and Sarri is optimistic that another potential recruit will complete the recreation of his Napoli midfield. CSKA Moscow have reportedly rejected a bid from Monaco for Aleksandr Golovin - who was one of the breakout stars of Russia - and the 22-year-old is close to agreeing a deal with the Blues.
But would this signing be the final piece to Sarri's midfield puzzle?

Setting out in a base shape of 4-3-3, the midfield was crucial in how Sarri coaxed a possession-based game out of Napoli throughout his time in Italy.
