Neymar took to social media to poke fun of Adrien Rabiot and his Paris Saint-Germain team-mates after Barcelona's remarkable Champions League win.
Barca overturned a 4-0 first-leg deficit at the Nou Camp on Wednesday, scoring three times in the final seven minutes to secure a stunning 6-1 (6-5 aggregate) victory over PSG.
Neymar clearly had not forgotten the humiliation of the first-leg loss, re-posting an Instagram image of Rabiot and left-back Layvin Kurzawa celebrating in Paris.
Over the image, in which Rabiot gestures the number four in reference to the 4-0 win, the Brazil international added the caption: "4+2=6".
Neymar produced a sensational second-leg performance to help Barca advance, winning a penalty, scoring two goals and assisting Sergi Roberto's dramatic volley.
The forward was also pictured alongside Mercedes F1 driver Lewis Hamilton after the victory. Hamilton is in Barcelona for testing ahead of the new F1 season, which you can watch live on Sky Sports.
