PSG defender Luiz celebrates after scoring against his former side Chelsea in the second leg round of sixteen of the Champions League on WednesdayReuters

Paris Saint-Germain defender David Luiz says he is sorry for celebrating after scoring against his former club Chelsea during the two sides' clash in the second leg round of sixteen of the Champions League at Stamford Bridge on Wednesday.

PSG managed to progress to the next round of the Champions League on away goals (3-3 aggregate) after coming back twice from behind to record a 2-2 draw at Stamford Bridge.

Gary Cahill put Chelsea in front in the 81st minute but Luiz cancelled out his strike in the 86th minute to force the game into extra-time. Eden Hazard again put Chelsea ahead via a penalty in the 95th minute, a late header from Thiago Silva saw PSG advance to the final eight of the Champions League on away.

Although it is considered disrespectful to celebrate after scoring against one's former club, Luiz could not resist.

And now the 27-year-old Brazilian, who spent three-and-a-half years at Chelsea before moving to PSG for a reported £50 million last summer, has apologised for his actions, insisting that he could not control his emotions.

"It was good for me to score. I said before I didn't celebrate but there was so much emotion I cannot control and sorry because I celebrated because of the emotion, but I am so happy to qualify," Luiz told ESPN.

"I finished at Chelsea and then I got a great opportunity from PSG - they gave me a great opportunity to continue my career and I was very happy at Chelsea and won titles here but I finished and then I respect everyone."

Meanwhile, the former Benfica man feels that PSG "played a great game" to draw against Chelsea despite them being reduced to ten men after Zlatan Ibrahimovic early sending off.

"I think we played a great game," Luiz told Sky Sports. "When we lost Ibra, our best player, you say 'keep it simple.' Play the ball to feet and keep possession as we need to score to qualify."

"It was amazing tonight the spirit. Every single player gave everything."
