Neymar returned to Barcelona to meet his old team-mates on Tuesday.
The player posted pictures of himself posing with Luis Suarez and Ivan Rakitic yesterday morning before darting across the city to the Casino Barcelona.
There he joined Barcelona defender Gerard Pique.
Neymar was in Barcelona for PokerStars European Poker Tour (EPT) match with his former team mate Pique and others.
The ETP is one of the most popular poker festivals in Europe.
With a buy-in of €25,000, the stars are playing for charities close to their hearts.
Neymar will join his PSG team-mate Giovani Lo Celso to play for The Neymar Jr.
The Neymar Jr is a project Institute, which offers free classes for football, volleyball, swimming, judo, basketball, reading, languages, music, dance and information technology to 2,300 under privileged children in Brazil.
The football star is no stranger to the poker table, having competed in his first EPT event in Barcelona three years ago in 2015.
Barcelona star Pique is playing for the Barefoot Foundation, a Colombian charity founded by his wife Shakira.
Pique has competed in EPT Barcelona events for several years, with his best result last year when he finished 5th in the €25,500 No Limit Hold’em for €129,350.
