Why do football fans record games they are at in person? We will never know.

It does create terrific raw footage though. Sergi Roberto's goal for Barcelona against PSG was one of the most famous in the history of the storied club.

Despite losing the first leg 4-0 in Paris, Barcelona somehow scored twice in the latter stages of the game. It was fitting that the winning goal be scored by Roberto, a product of La Masia.

Luis Enrique's side are now favourites to win the tournament, having gone into Wednesday's game as 40/1 outsiders to lift the trophy in Cardiff this summer.

Sit back, turn up the volume, and enjoy Roberto's goal in all of its raw glory. The Barcelona team and over 90,000 in attendance at the Camp Now certainly did.
