After last week's shock 3-2 loss at home to Burnley, Premier League champions Chelsea needed to respond against rivals Tottenham, and that's exactly what they did.
Spurs dominated possession, and their tally of 18 shots was twice as many as Chelsea, but the Blues scored with their only two efforts on target to win 2-1 at Wembley Stadium.
Marcos Alonso opened the scoring with a wonderful free-kick, and the team coped with everything Tottenham threw at them until Michy Batshuayi headed into his own goal in the 82nd minute.

In a dramatic finish, it was Alonso's low strike that gave Chelsea their first points of the new season, although goalkeeper Hugo Lloris could have done a lot better.
Antonio Conte was delighted with the spirit and work ethic of his players, and he went absolutely crazy after his left-wing-back drilled home an 88th-minute winner.
Conte celebrates Alonso's dramatic winner
The Chelsea manager has had to answer a lot of questions following the Burnley defeat, from his need for more signings to his treatment of last year's top scorer Diego Costa.
Back in a suit for Sunday's clash after sporting a tracksuit last weekend, Conte was at the very edge of his technical area as he watched Alonso's effort find the back of the net.
As you can see in the video below, the Italian literally couldn't contain himself as he celebrated the goal in wild fashion, leaping towards his backroom staff in absolute joy.
Conte handed first Premier League starts to £40 million midfielder Tiemoue Bakayoko, youngster Andreas Christensen and club-record signing Alvaro Morata.
Not only does the result get Chelsea's campaign up and running, it also continues the doubts so many people have about Spurs' ability to succeed at their temporary new home of Wembley.
Conte's slightly different system, with David Luiz in midfield and Willian in behind Morata, worked fairly well, and he'll be hoping for a similar outcome in their next match as they welcome Everton to Stamford Bridge.
