Thiago Silva???s header deep into extra time sent Laurent Blanc???s men through on away goals as they avenged their defeat to the Blues in the knockout stages last season.
It was a fiery match at Stamford Bridge as Zlatan Ibrahimovic saw red while several players were booked, with the tie threatening to boil over on several occasions.
Before Wednesday???s encounter Mourinho had criticised PSG???s ???aggressive??? approach to the game and the Chelsea boss again seemed unhappy with their opponents??? behaviour.
???They were aggressive the same way,??? he said.
???They were what we used to call on our side of the continent as clever. In England that is not accepted as clever, intelligent, experienced people but they did what they did.???
The Chelsea boss bemoaned the visitors??? tactics as they sought to close out a dramatic victory at the end of extra time, and insisted it???s not something that is usually seen in the Premier League.
???For example, after they scored their second goal there was no more game,??? he added.
???Time to celebrate, simulation of injuries, make a change??? they stopped completely the game which we could not do when 1-0 up with five minutes to go.
???I think it???s the beauty of English football but when we go into continental football the other teams are more prepared from a mental point of view. I don???t say dirty because that is not the word. I would say it???s a great part of the game.???
