Watch: Neymar, Sergi Roberto cap Barcelona's historic UCL comeback
Barcelona completed the greatest comeback in Champions League history, scoring three goals in the last seven minutes to stun PSG 6-5 on aggregate and advance to the quarterfinals.
Leading 4-0 after the first leg, PSG set out to avoid being on the wrong side of history, with no team in competition history ever overturning a deficit of such a size. But with Lionel Messi, Luis Suarez and Neymar, anything is possible, something that Barcelona teammates Ivan Rakitic and Marc-Andre ter Stegen are touted heading into Wednesday's second leg.
That proved to be the case. Neymar's free kick and penalty in the 88th minute and the first minute of stoppage time brought Barcelona to the cusp, and Neymar's assist to Sergi Roberto in the final minute of added time secured the unprecedented triumph.
Suarez got things going for Barcelona early, getting the final touch on a ball errantly hit backwards toward PSG's goal in the third minute:
Barcelona ramped up the pressure after that. Messi's free kick from 25 yards narrowly missed the right post, while a chance from Neymar in the 19th minute was inches from picking out the upper right-hand corner.
In the 28th minute, after another extended possession for Barcelona in PSG's half, Andres Iniesta whizzed a blast from long range out of the reach of goalkeeper Kevin Trapp, but just over the bar.
Barcelona's pressure was finally rewarded with a second goal, with Iniesta forcing an own goal off Layvin Kurzawa on a back-heel from an acute angle in the 40th minute, getting the hosts halfway there before halftime.
Barcelona made it 4-3 minutes into the second half from the penalty spot. Neymar was taken down by Thomas Meunier after being played through by Iniesta, and Messi delivered on the 50th-minute spot kick, bringing Barcelona to the cusp of completing its comeback.
A rare PSG foray forward followed the goal, with Cavani hitting the post to put a momentary scare into Barcelona's hopes, but the Uruguayan finally broke through shortly after.
His powerful volley from inside the box gave PSG the away goal it sorely craved to alleviate the pressure, forcing Barcelona to need three more goals to advance.
Neymar did what he could in the late stages of the game to make the comeback happen. His sensational free kick was followed by a penalty kick, evening the series on aggregate and leaving PSG ahead solely on away goals.
Sergi Roberto capped the sensational comeback to send Barcelona through off Neymar's assist, with his flying volley from close range sending Camp Nou into hysterics.
