Five-time winners Barcelona have not failed to reach the last eight since the 2006/07 season but they will need to produce something special to turn this tie around after a PSG masterclass at the Parc des Princes.
Di Maria, on his 29th birthday, got things rolling with an 18th-minute free-kick and Julian Draxler doubled the home side’s advantage just before the break to leave Barca, champions in 2009, 2011 and 2015, on the ropes.
And things went from bad to worse for the Catalan giants as another fine strike from outside the box by Di Maria made it 3-0 in the 55th minute, before his fellow Argentinian Cavani added a fourth with 19 minutes to go.
