Chelsea boss Antonio Conte has declared David Luiz "amazing" after victory at Tottenham.
Conte was pleased with the efforts of Luiz, Alvaro Morata and Tiemoue Bakayoko as he confirmed his hunt for new players continued.
He said: "Luiz's performance was amazing.
"He played with great discipline, intelligence and in a difficult game with a new system, he was amazing.
"This is a perfect response of the champions.
"We won the league last season, winning 30 games, and that is not easy. We lost in the final of the FA Cup.
"We have arrived in some problems with bans and injuries but we must be ready to work and focus on the pitch.
"The club is trying its best in the transfer market to improve our squad but I must be happy."
