PSG went into the match with a resounding 4-0 lead from the first leg and had their one foot in the last eight stage of the tournament. They had only one job and that was to defend their 4-goal cushion against Barcelona. [Historic comeback: Barcelona stun PSG 6-1]
But Barcelona had other plans and they executed it right from the word go. They attacked from the very first move and got the opening as early as in the third minute.
Luis Enrique tweaked his tactics and fielded his team in a 3-4-3 formation in this do or die clash. PSG went on the back foot from the beginning which actually cost them the match.
Barcelona were battling against the odds as no team in the history of this competition had overturned a 0-4 deficit from the first leg.
But the Catalan giants were brave. They dreamt of turning the odds in their favour and do the unthinkable.
And as they say, fortune favours the brave, Barcelona did it. They scripted a fairytale which became immortal in the history of the game.
Echoing the general sentiment of the fans, Barcelona coach Luis Enrique said: "It is difficult to explain in words. This is a sport for crazy people, a unique sport.
"Any kid who was in the Camp Nou tonight will never forget this in their life. It was a torrent of feelings. I don't cry - I would like to, but the tears don't come out. But I enjoyed this as much as the rest; as much as those who cried."
The coach further said that they believed in themselves. They kept the faith that they can do it.
Enrique continued: "Faith is the word that best defines this tonight. Above all, this is a victory of faith. The faith the players showed, the faith the supporters showed.
"I have only ever seen the stadium like this once before, and that was back when I was playing. Normally with 10 minutes to go, people are leaving the stadium.
"But tonight they didn't. If any went, stuff them, they have missed a historic night. In the end, we have had a special night.
"I would like to dedicate this to all Barcelona fans, but especially those that kept supporting us after the 4-0 [in Paris].
"We had that mourning on Valentine's Day, and we were given a good going over. We had nothing to lose today, we had lost everything in Paris. But this wonderful sport is unique, it always gives you the chance for revenge."
Fans around the world, irrespective of the allegiance, hailed Barcelona for their heroics at Camp Nou. It was a special night at Barcelona which no fan can ever forget.
