The Blues maintained their unbeaten start to the season with a romping 4-0 win over Burnley at the weekend, where Sarri’s men exhibited the free-flowing passing football which the Italian became synonymous with at previous club Napoli.

Sarri has received many plaudits for Chelsea’s attractive football and his reinvention of young English talent such as Ross Barkley and Ruben Loftus-Cheek. Luiz, who confirmed he would have left Chelsea if Antonio Conte – now linked with the Real Madrid job – had remained in charge of the club, has hailed the leadership of Sarri for transforming the team’s and his own personal fortunes.

‘I think when you are a leader, you try to give that for the others. Sarri is our leader, he tries to show us what he wants to do and that’s it. We follow him.

We just try to enjoy, to do our best and try to win some games. I think life is also about that’, he told Goal.

‘If you are not happy about something then you have to change so this is the main thing you have to do every single day. It is one of the best jobs in the world. So we try to train hard every day, to train with discipline, to try to play with responsibility but also happiness.

‘Of course, he has his philosophy and he tries to show us every single day. We try to improve ourselves and the team. We are trying to do it. The results are coming because we are working hard every single day.

I am so happy also because he is a great human. ‘He knows how to teach us, how to improve us, when he is like that then it is easy to understand him and to try to be fantastic inside the pitch. I think I had the opportunity to play in many fantastic squads and I won with a great teams and lost in great teams. I think this team is trying to improve every day.

‘The manager has been here for three or four months now. He is trying to improve our style of football and philosophy. The Premier League is not easy. It is just the beginning, we are keeping our feet on the ground and going game-by-game.’ Chelsea currently sit second in the Premier League table, two points behind early pace-setters Liverpool.
