Remarkably, it’s now three years to the day since Barcelona beat Paris Saint-Germain 6-1 at Camp Nou to qualify for the quarter finals of the 2017 Champions League.

Unless you’ve been living under a rock for the past few years, you’ll be aware that the match was one of the greatest in the history of world football, let alone European competition.

PSG had put Barça to the slaughter in the first leg, and galloped to a 4-0 victory in front of their home faithful at Le Parc des Princes. Angel Di Maria scored two, alongside Julian Draxler and Edinson Cavani.

Barcelona, including their golden trio of Messi Suarez and Neymar, were absolutely slammed in the media after that game for their carelessness on the ball and apparent cluelessness without it.

Everybody wrote them off and immediately began talking about PSG, who had never progressed beyond the quarter finals of the competition at that point, as potential Champions League winners.

But what happened next was truly remarkable, unprecedented in the history of the competition, and reminded us all that football has never been - nor will ever be - a predictable game.

With the eyes of the world upon them, Barça wrote their name into the history books by becoming the first team to overturn a first-leg 4-0 Champions League deficit - and they did so in style.

They flew out of the starting blocks, with Luis Suarez scoring a header after just three minutes, and an own goal from Layvin Kurzawa made it 2-0 to Barcelona at the break.

This gave a glimmer of hope to the Barça faithful in attendance, but given that their side were still 4-2 down on aggregate, the possibility of qualification still remained a pipe dream at this point.

Messi converted a penalty just after half time to make it three, but once Cavani fired home for PSG after 61 minutes, there looked to be no hope left for Barça.

Another 25 minutes passed, with no goals. With 87 minutes played, Barcelona found themselves still 5-3 down on aggregate and crashing out of the tournament. But that’s when things got really crazy.

Neymar curled in a beautiful free-kick to make it 5-4 on 88 minutes, and held his nerve to convert a penalty to make it 5-5 in added time. They were one goal away, and had almost no time left to find it.

But once again, Neymar had other ideas. He set up substitute Sergi Roberto, a Barcelona academy product, to poke home his first goal of the season on 95 minutes, and Barça were through.

Camp Nou exploded. The record books were re-written. Football history had been forever changed, and the memory of that night will forever live on!
