Chelsea defender David Luiz insists their form reversal has not come from any change in manager Maurizio Sarri's style.

Despite some modifications, Brazil defender Luiz dismissed suggestions that Sarri had dispensed with his philosophy.

And the 31-year-old also insists he and his team-mates are fully behind the tactics.

"Change the style? I don't think so, the style didn't change," he said.

"We just adapted some moments of the game, like the line to have high pressure or not.

"But our philosophy is to play from the back with possession and try to control the game.

"For many years everybody said Chelsea were winning but never controlled the game. Now we control the game and people say we don't win.

"Every player believes in his philosophy and everyone is giving 100 per cent to achieve our goals."
