WATCH: Benni, Kuffour celebrate Barca's comeback

Cape Town - Sergi Roberto scored in the fifth minute of stoppage time as Barcelona capped a sensational Champions League fightback to thrash Paris Saint-Germain 6-1 and reach the quarterfinals on Wednesday.

Despite Luis Suarez's early opener, a Layvin Kurzawa own goal and Lionel Messi's penalty, Barca, who lost the first leg 4-0, looked down and out when Edison Cavani volleyed home what seemed to be the vital away goal for PSG.

However, Neymar restored Barca's belief as he firstly fired home a sensational free-kick two minutes from time and then converted from the penalty spot.

And Roberto capped the biggest comeback in Champions League history when he stretched to turn home Neymar's dinked cross to the delight of a near 100 000 at a rocking Camp Nou, making the score 6-5 on aggregate.

Barca also enter the record books by reaching the quarter-finals for a 10th straight season.

PSG president Nasser Al-Khelaifi was blunt in his summary.

"It's a nightmare for everyone. Three goals in seven minutes is very difficult. Everybody is upset but now is not the time to talk about it."

Enrique warned the French champions on Tuesday that his side were capable of scoring six and they needed the full 95 minutes to pull of a miracle revival.

No side had ever come back from a 4-0 first leg deficit in the Champions League, but after much pre-match hype of a historic turnaround, Barca truly believed when Suarez opened the scoring after just three minutes.

Meanwhile, in South Africa SuperSport TV football analysts Andre Arendse, Benni McCarthy, Sammy Kuffour and John Barnes could not contain their excitement as Roberto's goal secured Barca a quarter-final spot.
