Wonderful from Kylian Mbappe! Wonderful from Paris Saint-Germain as they run away with a massive win over their host.
With Barcelona throwing men forward in the hope of salvaging the tie, the visitors have picked them off in style.
Substitute Julian Draxler does brilliantly to lead the charge, drawing the remaining defenders, and then slipping a well-weighted pass left to Mbappe.
There’s still much for Mbappe to do, but he does it incredibly well, planting a first-time curling shot beyond Marc-Andre Ter Stegen and into the top corner. Sensational!
It’s the first hat-trick scored by a visiting player in the Champions League since Andriy Shevchenko for Dynamo Kiev in 1997.
It was Barcelona who took the lead as Lionel Messi scored from the spot.
Mbappe cancelled the lead and scored the second and he equally scored the last goal of the night.
It will now be difficult for Messi and Barcelona to win by four goals to nothing at France.
