Barcelona are on course to make the Champions League semi-finals after taking their aggregate lead against Paris Saint-Germain to 5-1, a Neymar double putting the Spanish giants 2-0 up at the break.
The visitors, chasing a two-goal deficit, got off on the wrong foot when David Luiz was booked just three minutes in for a challenge on Ivan Rakitic.
Luis Enrique's charges were rampant in the early stages and took the lead in the 14th minute when Andres Iniesta skilfully beat three opposition players before playing in Neymar, who then skinned Luiz, went round Salvatore Sirigu and slotted in.
PSG could have been level three minutes later as Blaise Matuidi's deft back-heel found Zlatan Ibrahimovic, who rifled a shot into the bottom corner of the net, but the goal was ruled out for offside.
Nevertheless, Barca were clicking together and doubled their lead just after the half-hour mark thanks to Neymar getting ahead of Luiz and heading home Dani Alves's cross to all but kill off PSG's hopes of progressing.
