Messi netted twice on the night, dribbling into an empty net after Luis Suarez hit the crossbar to put Barca 2-0 up. But it was the little Argentinian's second goal of the night that had social media buzzing.

Messi stepped up and planted a 25-yard free-kick perfectly into the top left-hand corner, leaving Liverpool keeper Alisson Becker grasping at air as Barca went 3-0 up in the tie.
