David Luiz says Maurizio Sarri has been angrier after wins than he was after Chelsea were beaten by Tottenham.
Spurs secured a convincing victory on Saturday to inflict the first Premier League defeat of the season on Sarris Chelsea.
The result saw Tottenham leapfrog above Chelsea in the table, with Mauricio Pochettinos side now third, five points adrift of leaders Manchester City.
Spurs raced into a two-goal lead at Wembley through Dele Alli and Harry Kane, while Son Heung-min put the home side further in front after half-time.
Brazilian defender Luiz admitted Sarri was not happy after the defeat but says the Italian coach has been angrier after victories.
He said: [Sarri] has been, many times, angrier when weve won. Its true. Nobody is happy. Of course the coach is not happy.
He always tries to do his best for us, and we try to do our best for him. Of course, hes not happy like every single player is not happy.
But I think its good for us to understand, to remind us that the Premier League is never easy. Its not easy to win any game.
Like I said, we didnt play well. We played really badly, we didnt have the same intensity as in the other games.
The good thing is that we have another game next week, so an opportunity to recover and gain some points.
Then, soon, we have City, a tough team, the top club in the table. So we can try and make the gap a bit smaller then.
Luiz added: It was our first loss, but even if you win you have to analyse and improve. Thats the only way to success.
We will analyse as soon as possible what we did badly, to improve it in the week, and to try to do better in the next game.
Sarri, meanwhile, described his teams performance in north London as a disaster and said not one of his players deserved praise.
Asked whether he was happy with Ross Barkleys cameo appearance, the Blues boss said: No. Today I didnt like anybody.
The defensive phase today was a disaster. I am not talking about the defensive line but the [entire] defensive phase.
The offensive players pressed very badly, the midfielders defended not very well and the defensive line, as a consequence, was a disaster.
The defensive phase of the team was a disaster. In the first 25 or 30 minutes, we had big problems to exit from our half.
We lost a lot of balls and, against Tottenham, it is very dangerous to lose a lot of balls in your half. In the short counter-attack, they are probably the best in Europe.
