David Luiz has revealed that the 3-4-3 formation that Antonio Conte has implemented at Chelsea this season has been great for his game.

Although David Luiz's physical attributes are undeniably excellent, this season has seen him raise his game not only on the pitch, but in his head.

Speaking before the Blues take on Middlesbrough at Riverside Stadium tonight, Luiz said: "I started in this system when I was young, a long time ago, and now I come back to play in the back three. In this system you work a lot in a tactical way.

"Conte gives me a lot of good advice in ways to read the game.

"In my position I need to be the cover for everybody, the cover for the midfielders and the defence and the wingers. It's a tactical place, and I love to work with Conte, he loves to work on the details. He's helped me a lot and he's great to work with."
