PSG without Neymar thrashes Barcelona in their away encounter in their last-16 first leg on Tuesday to move within full view of the Quarterfinals.
Barca started the game with the lead as their star striker blasted the team ahead with a penalty in the 27th minute.
Kylian Mbappe who had not scored in UCL knockouts for the last two years quickly equalized the score in the 32nd minute.
Mnappe put the team into the lead in the 65th minute. Moise Kean took advantage of some woeful Barca play and took the team ahead with the third goal in the 70th minute. Mbappe completed his hattrick in the 85th minute when he curled the ball past Ter Stegen into the top corner.
Barca will be looking forward to repeating 2017's 6-1 win against PSG in the second leg when the team was down 4 nil after the first.
