Chelsea boss, Maurizio Sarri, has named one of the club's players that surprises him the most.
The Italian admitted he has been surprised by defender, David Luiz's intelligence since arriving at Chelsea.
Sarri took over from Antonio Conte in the summer and Chelsea remain unbeaten in all competitions so far this season.
Brazilian defender, Luis was left out of the team during Conte's final campaign as manager but he has returned to the side to forge a solid partnership with Antonio Rudigar.
"There is an infinite passion and what I have seen so far, it has been expressed in the right way," Sarri told Gazzetta dello Sport.
"David Luiz surprised me with his awareness and intelligence, [Ross] Barkley has found continuity after a long period marked by injuries.
"Willian is a player of immense quality. His style of play is perfect for England.
"And [Alvaro] Morata is a quality, fast and technical guy.
He has a great sensitivity and the difficulties had hurt him."
