PSG voiced their support of Neymar and called for an investigation from French football's authorities, while Marseille insisted Gonzalez is not a racist and claim he has received death threats after his phone number was leaked.
The 33-year-old shared a picture of French rap group Bande Organisée, but with the members' heads replaced by those of some Marseille players and coach Andre Villas-Boas, while Neymar's head has been photoshopped onto the body of a dog being held by Alvaro Gonzalez.
A tussle between Argentine pair Dario Benedetto and Leandro Paredes quickly escalated into an all-out brawl between PSG and Marseille players, with Neymar in the thick of things. Now I want to see it pick up the image of the racist calling me a 'monkey so on a *****'. that is what I want to see!
The Brazilian was arguing with the Marseille central defender all game and claimed he was racially abused by the Spaniard in the first half.
"He told me I played lottery tonight, I told him he played lottery too against Atalanta [in last season's Champions League quarter-finals]". "Racism in life, in all domains, in sport, should not exist".
Once order was restored referee Jerome Brisard showed a straight red to Neymar, Kurzawa and Amavi for their part in the fracas, the former going following a consultation with VAR, with Paredes and Benedetto also ordered from the field after picking up second bookings. "We will have to look at everything to take a coherent stance but the situation is serious".
"Fourteen yellow cards and five reds means the match was out of control", said the Brazilian. "It's a very good win, a tough and obviously hard one", said Villas-Boas. PSG lost their opening two league games for the first time since the 1984/85 season and Tuchel may find himself under early pressure.
