Thierry Henry says Chelsea proved their quality by responding to the opening-day Premier League defeat against Burnley with a 2-1 win over Tottenham at Wembley.
The Blues lost 3-2 to the Clarets and came in for plenty of criticism.
But two Marcos Alonso goals earned them victory against a Spurs side who dominated possession.
The victory came despite Eden Hazard being out and Chelsea also being without the suspended Gary Cahill and Ces Fabregas.
Speaking on Sky Sports, former Arsenal striker Henry said: “The lion will always be a lion. Against Burnley it was a first half of madness.
“Chelsea came to do a job in a very Italian way and they stopped Tottenham playing their usual way. Everyone asked questions of Chelsea and they answered them. When you work very hard as a team you get your rewards.”
Former Scotland, Liverpool and Spurs midfielder Graeme Souness praised Chelsea’s discipline after they came from behind to beat their London rivals.
“They reacted to the defeat, and the questions put against them after last week,” Souness said.
“They responded how big teams respond. They were so disciplined, so together.
“They were clinical when they had to be and won the game against one of their biggest rivals
“They have answered those questions and they are still a team to be feared.”
