Paris: Neymar appeared to aim a punch at a fan goading him following Paris Saint-Germain's surprise French Cup final defeat to Rennes on Saturday.
The Brazil forward was walking up the stairs to collect his losers' medal at Stade de France when he was involved in an altercation. Videos since shared online showed the fan mocking PSG players as they walked past, filming them on his phone.

When it came to Neymar's turn, he stopped, looked at the man who was grinning at him, pushed his phone down and then flicked a quick jab with his right hand that caught the man around the chin area.
The man stepped back but did not appear to be hurt.
Rennes won the Cup in a tense penalty shootout after fighting back from 2-0 down to force extra time. It was the club's first trophy since winning the Cup in 1971 and prevented PSG winning it for a fifth straight season and a record extending 13th time overall.
Neymar had set up PSG's first goal for countryman Dani Alves and scored the second midway through the first half.
Neymar's temper got the better of him earlier this season after PSG lost to Manchester United in the Champions League.
Following the round-of-16 game in March, Neymar used Instagram to aim an expletive and insults at video review officials who intervened before Man United was awarded a stoppage-time penalty for a handball that eliminated PSG.
UEFA banned Neymar for three matches for insulting the officials, meaning he misses French champion PSG's first three matches in the Champions League next season.
