Chelsea defender David Luiz has stressed that he and his team-mates trust in boss Maurizio Sarri's philosophy and that "everybody is with" the Italian.

The Blues put in a disappointing performance as they were beaten 2-0 at Arsenal on Saturday.

The gap between Chelsea in fourth place in the Premier League and Arsenal, who rose to fifth, reduced to three points, and sixth-placed Manchester United are the same amount behind Sarri's men.

In his post-match press conference, an angry Sarri was critical of his players' mentality, accusing them of being "extremely difficult to motivate".

Luiz said the manager "was not happy" after the match "but nobody was happy, so it was normal."

And regarding the way Chelsea have been playing, he said: "It is our style, it is our philosophy.

"I think if you asked at the beginning of the season, 'can Chelsea keep the ball?' – you would have said no.

"And now we are able to do that, like the best teams in the world, but then we have (to) improve our last 25 metres."

The Brazil international added, when asked if it was harder to trust the philosophy when Chelsea lost: "It is part of the process, when you try to do something and this is inside your mind, if you believe in it you can arrive there.

"Because of the results if you start to change and change, you don't go anywhere.

"So this is our philosophy, I believe in it, I trust in it, so I just know we have to improve, like every team in the world.

"But then after that possession and being more dangerous is two different things, so I think we had the possession but we still have to be more dangerous."

Luiz said the creation and conversion of chances was an area in which Chelsea "have to improve", and added: "When I say that I am not talking about the strikers, I am talking about the whole team.

"The offensive phase starts with (goalkeeper) Kepa (Arrizabalaga), and then with us the defenders, with everybody."
