Neymar struck twice in Barcelona's 2-0 win over Champions League opponents PSG.
Barca did most of the damage in the first leg with a 3-1 win in Paris and they finished the job off with relative ease at the Nou Camp, with two first-half Neymar goals earning a 2-0 win.
The 5-1 aggregate victory also keeps Barca firmly on course for the treble, having already reached the final of the Copa del Rey and boasting a two-point lead in La Liga with six games to go.
"We made a great start to the game, with almost perfect pressing from the off. The players understood perfectly what the game demanded," said coach Luis Enrique.
"I hope the best is still to come."
