Lionel Messi's penalty against Paris Saint-Germain saw him equal Cristiano Ronaldo as the Champions League's most potent player from the spot.
Chasing an incredible four-goal comeback in Camp Nou, Barcelona were 2-0 up when Neymar was brought down in the area.
After consulting with the official behind the goal, referee Deniz Aytekin eventually gave the spot-kick in the Catalans' favour, and Messi made no mistake in drilling home to Kevin Trapp's right-hand side.
And in doing so, the Argentine drew level with his eternal Real Madrid rival in Champions League spot-kicks.
Messi has now scored 11 times from 12 yards in the European competition, the highest of any player in competition history alongside Ronaldo.
In converting against PSG, he also marked his 37th knockout goal - a figure that puts him behind only Ronaldo.

The goal put Barcelona 3-0 ahead, although Edinson Cavani pulled one back to necessitate at least three more home goals for the Catalans to go through.
