Barcelona made history on Wednesday night by becoming the first team to win a Champions League tie from 4-0 down after the first leg.
Paris Saint-Germain battered the Catalonians at the Parc des Princes and were heavy favourites to progress when they travelled to the Camp Nou.
No one could have predicted what would happen next, though.

Luis Suarez sparked the comeback in the 3rd minute by heading over Kevin Trapp from close range, with Layvin Kurzawa scoring an own goal just before half-time.
A 50th-minute penalty from Lionel Messi then made it 4-3 on aggregate but, against the run of play, Edinson Cavani struck back to give PSG the away goal advantage.

At that moment, the result seemed beyond doubt. But this is Barcelona we're talking about here, and in the 88th minute, Neymar found the top-left corner with a stunning free-kick to make it 5-4.
The Brazilian then clawed another one back from the penalty spot after the referee controversially blew for a foul on Suarez.
And then, with seconds remaining, Neymar found Sergi Roberto inside the 18-yard box to poke past Trapp and send the Camp Nou into delirium.
It was a truly incredible moment as Barcelona's players and coaching staff celebrated wildly, but an even better video has now emerged of Roberto's goal.
Some genius out there has made a mashup of Barca's dramatic winner with the Titanic theme song - Celine Dion's 'My Heart Will Go On'.
And it's absolutely incredible. Prepare to feel very emotional.
BARCELONA + TITANIC = PERFECTION
How's that for spine-tingling? This lad summed up the collaboration perfectly.
Speaking after the game to BT Sport, Ivan Rakitic described the result as "crazy" and likened it to the New England Patriots' recent comeback in Super Bowl LI.
"No, I cannot believe it," he said, per Goal. "It was really impossible. [Now] 15-20 minutes after the game, it is crazy and unbelievable.
"Thank you to the team, to the people around the club and the fans. It was a really special day and it is hard to say something.
"The first game in Paris was hard for us, a lot of people spoke hard with our team but the reaction was special. It is history. We want to keep going on.
"We had to believe [because] 4-0 was hard, but it is football. We saw it in the Super Bowl, what is possible in sport. Today was crazy.
"This is Barcelona, the best team in the world and we want to continue our dream in the Champions League."
