David Luiz admits Chelsea's players are enjoying working with "football lover" Maurizio Sarri.
The defender has been able to revive his Blues career since the Italian's appointment.
“I love his philosophy. It's amazing," Luiz said.
“Before everything he is a great person, as a human he talks with us every single day, he enjoys what he does.
“He is a guy who really loves football, and it's always special to work with people like him."
He started as Chelsea defeated Cardiff 4-1 on Saturday, to continue their blistering start to the season.
Luiz explained that he enjoys the style of football Sarri has introduced, and he is optimistic for the rest of the season.
“With a team like Cardiff, they play physically, with a defensive style, a lot of long balls, fighting for free-kicks.
“It's not easy to score one goal against them, but we scored four.
“We tried to keep the ball, move quickly to create the gaps and score goals."
