Paris Saint-Germain goalscorer David Luiz apologised for celebrating his goal against former club Chelsea as the English side exited the Champions League following a 2-2 draw at Stamford Bridge . Chelsea were eliminated as the tie went into extra-time as 10-man PSG twice came from behind to win an ill-tempered last-16 tie on away goals . The first leg was drawn 1-1 and Chelsea 's advantage grew when Zlatan Ibrahimovic was sent off after 31 minutes . David Luiz celebrates wildly after sending the game into extra time with a bullet header at Stamford Bridge . The Brazilian defender could n't hide his emotion , but later apologised for celebrating against his former team . Luiz said he was sorry that he had celebrated , but that he had been unable to control himself in the moment . Gary Cahill 's strike nine minutes from the end of normal time was cancelled out by former Chelsea defender Luiz , but the hosts went ahead for a second time through an Eden Hazard penalty early in extra-time . PSG captain Thiago Silva , who conceded the spot-kick for handball , was denied from a corner by Thibaut Courtois but then netted with a header moments later to make it 2-2 on the night and send the visitors through . ' I think we played a great game , ' Luiz told Sky Sports 5 . '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 . The powerful header took the game into an extra 30 minutes , in which Thiago Silva scored the crucial goal . Luiz sinks to his knees at the final whistle , celebrating the win for his new club against his old employers . ' 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 . 'It was good for me to score . I said before I did n't celebrate but there as so much emotion I can not control ( it ) and sorry because I celebrated because of the emotion but I am so happy to qualify . ' In a feisty contest , Luiz clashed with his former manger Jose Mourinho after Zlatan Ibrahimovic was sent off . Luiz and Diego Costa came together several times , and the Brazilian defender was lucky not to be dismissed .
