Just minutes away from elimination, Barcelona had to conjure up three instant goals and it was Neymar who stepped up.

The Brazilian striker first scored from a free kick in the 88th minute then a penalty two minutes later before floating a perfect pass for Sergi Roberto to score the dramatic winner in the fifth minute of injury time as Barcelona beat Paris Saint-Germain 6-1 to complete the biggest ever comeback in the Champions League.

Roberto's strike gave his team a 6-5 victory on aggregate, making Barcelona the first side to overturn a 4-0 first-leg defeat since the current format started in the 1992-93 season.

Covering the match as football analysts on the night for BT Sport, Rio Ferdinand, Steven Gerrard, Michael Owen along with host Gary Linekar could not contain their excitement after Roberto's last gasp goal went in.
