David Luiz insisted that Paris Saint-Germain had stayed true to their "philosophy" in order to knock Chelsea out of the Champions League at the round of 16 stage for the second successive season.
Having triumphed 2-1 in last month's first leg at Parc des Princes, PSG took firm control of the tie on 16 minutes when Adrien Rabiot slid in to convert Zlatan Ibrahimovic's low cross from the right flank.
Diego Costa gave Chelsea hope when he turned Thiago Silva to equalise on the night 11 minutes later, but the Spain international was forced to leave the field with a tendon injury after the break and Ibrahimovic made sure of PSG's victory shortly afterwards, slotting in from a pinpoint Angel Di Maria cross.
The result ensured that Luiz left Stamford Bridge a victor for the second time in the Champions League since his £50 million move to PSG from Chelsea in the summer of 2014, and after the match the Brazilian said he was happy with his team's performance.
"It was a difficult game for us," Luiz told BT Sport. "I think [Chelsea] played very well, especially in the first half but we never changed our philosophy to play with the ball. We like to play with the ball, have possession to try to create some gaps to score. I'm very happy with the performance.
"I think it was a collective victory because everyone knows that to play here against Chelsea is always difficult. We were patient and had the experience to keep calm because they always put pressure on, and we scored in the best moment."
Ibrahimovic's goal and assist marked a happy return to Stamford Bridge for the Swede, who was sent off during last season's corresponding fixture between the two teams for a late tackle on Oscar and subsequently described the Chelsea players who surrounded Dutch referee Bjorn Kuipers as "babies."
"I stayed more than 20 minutes!" he joked. "That was my luck today and we did a good game. We played a very stable game, very patient in our possession like we want to play, and when we had a chance to strike we scored two goals. We had more chances but we did enough to win the game.
"It wasn't easy because when you play against a team like Chelsea [you know] the four players in front are able to do anything.
"We wanted to control the game. They were letting us control the game and striking when we made our mistakes, and that's how the [Chelsea] goal came. But it was a solid game. We're happy and we're through."
