Chelsea's David Luiz is relishing his new role at the heart of Antonio Conte's three-man defence.

The 29-year-old came under scrutiny in the weeks following his deadline day move back to Stamford Bridge, but has excelled as an integral part of a Chelsea backline that has kept four straight Premier League clean sheets following a formation shift.

In Conte's current system the Brazilian operates as a central defender between Cesar Azpilcueta and Gary Cahill - a position Conte says requires a 'more tactical' approach.

And Luiz believes the role is bringing out his leadership qualities.

"I have the best job in the world and it doesn’t matter which system we play," he adds. "You need to do what’s required in your particular role but I want to do my best for the team, not for myself. I have to be alert, to look around and to cover because it’s important for me to have that vision.

"I think Azpi and Gary have more opportunities on the ball than me in this formation but against Leicester I was able to get on the ball a lot. When you play with three in defence you try to play out from the back into midfield so they can create more.

"I have that side of my personality, to be a leader and to organise. A leader needs to be available to give something for others. I’ve had that in my character since I was young but of course I understand that now there is a responsibility, as somebody who has been here before and played many games, to use the experiences I’ve picked up in my career to help the youngsters."
