Neymar rubs salt in PSG's wounds: '4+2=6'

Brazilians know how to twist the knife. For example, during events at Rio 2016, the locals entertained themselves by counting up to 23, referencing how many years it had been since Argentina won a senior title in football.

On Wednesday, Neymar, who scored two goals as Barcelona produced the greatest comeback in the history of the Champions League, didn't hesitate to enjoy himself at Paris Saint-Germain's expense. The Brazilian phenom took to social media in the aftermath of the triumph, adding to his story on Instagram by writing "4+2=6" over a photo of Adrien Rabiot and Layvin Kurzawa holding up four fingers and two fingers, respectively.

The photo was initially posted by Rabiot after PSG's 4-0 victory over Barcelona in the first leg of the tie in the Champions League's Round of 16.

Prior to the second leg, Neymar used social media to express Barcelona's faith in overturning a four-goal deficit, writing: "As long as there's a 1 percent chance, we'll have 99 percent faith."

Neymar's two goals came in the span of seven minutes and 17 seconds, the first of which came from a perfect free-kick that curled into the top corner by the near post, and the other of which came from the penalty spot. After the final whistle, he took to Twitter, writing: "Respect our history, understand?" Note how many fingers Luis Suarez is holding up.
