David Luiz says he feels in the best form of his life at Chelsea.

The Brazil international is in his second spell at Stamford Bridge, having spent two years at PSG, winning six trophies between 2014-16 after a £50m switch.

When asked if he was performing at a higher level on his return, he said: “Yes, if not that means I'm going the wrong way. You need to be ready to improve every day and be available to do that immediately, from your first day. If I think I am the same player as many years before, this is not a good mentality.

“I improve every day. It was a new League with a new philosophy [at PSG], different players and a different culture, so I was happy there. I won a lot and learnt a lot."

The impressive run has coincided with coach Antonio Conte's switch to a 3-4-3 formation but Luiz insists the players deserve a lot of credit for making the transition so smoothly.

He added: “Everybody has understood the philosophy quickly, it's part of the changing dynamic of football."
