Having scored twice himself, the forward then capped a superb display to lift the ball over the PSG defence, where Roberto was waiting to poke the ball past Kevin Trapp in goal.
The Brazilian equalled the record of seven back in November, setting up Lionel Messi to open the scoring in Barcelona's group stage game against Celtic, though it was the meeting between the sides at Camp Nou which set him on his way.
In Barcelona's 7-0 victory over Brendan Rodgers' side in September 2016, Neymar registed four assists and a goal inside the 90 minutes to complete the rout in Catalonia.
He then followed up in Barca's following European tie, a 2-0 away victory against Bayer Leverkusen, applying the pass for Arda Turan to level the game for his side, before Gerard Pique secured the win.
Neymar grabbed his sixth assist of the European campaign by teeing up Messi in Barcelona's 3-1 defeat at Manchester City and his seventh, a record under current format which began in 2003-04, in the final group fixture away at Celtic.
