​New ​Chelsea boss Maurizio Sarri has revealed that defender David Luiz has surprised him both "as a player and as a man" ever since he took charge of the Stamford Bridge outfit in the summer.

The Brazilian who sometimes struggles with consistency has started and played every minute of Chelsea's first seven Premier League games so far, and was immense against Liverpool during their 1-1 draw, with the defender clearing one goal-bound header from Roberto Firmino.

This is a remarkable return to prominence for the 31-year-old who was frozen out of the team by former boss Antonio Conte, with the player confirming that he would have left the club in the summer if the Italian would have remained as boss this season.

Sarri for his part believes that Luiz is suited to his style of play and likes his attitude both on and off the pitch.

"I have to say he is better than I thought before, really better. As a player and as a man. I don't know [what happened] before, but when I arrived here immediately I had the feeling he is a very good player for my way of football because he is a very technical centre-back. Then, I appreciate very much the man," ​Sarri said as quoted by ESPN.

"He is direct. If he has to say something to the manager, to talk to me, he [comes] direct to me."

Under Sarri, the Blues have enjoyed a good start to the season and are currently placed third in the league with 17 points from seven games.
