Carlo Ancelotti says it will take some time for him to come to terms with PSG's Champions League heartbreak against Barcelona.
The Ligue 1 leaders looked set to record a sensational upset when Javier Pastore put them ahead on Wednesday, and 3-2 ahead on aggregate, just five minutes into the second half of the second leg at Camp Nou.
However, Pedro equalised soon after for the hosts, who held on to progress to the final four on the away goals rule.
"It's hard to be eliminated after what we did tonight," Ancelotti told Canal+.
"We were a little timid in the first leg and the result (2-2) was not good.
"But after tonight's game, while we feel regret, we also feel pride. We are proud because we did everything possible to win.
"We played well - didn't just defend - and that is why I want to thank all the players. We were so close to winning this game. This could have been a fantastic night for us."
PSG will now have to regroup in time for this weekend's Ligue 1 meeting with Troyes, as they aim to extend the seven-point lead they hold over second-placed Marseille.
