On a night where Messi was present at the Camp Nou, Kylian Mbappe stole all the headlines as he inspired PSG to a 4-1 victory.
The game started well for Barcelona with Messi giving them the lead until it all changed.
Mbappe netted a hat-trick in the famous victory before Moise Kean completed the rout late on with a header to turn the game around.
The Frenchman became only the third player ever to score a Champions League hat-trick against Barcelona. In fact, the PSG star was not born the last time a player achieved this feat against the Catalan giants.
