Brazilian TV station Globo Esporte reports that PSG have submitted a video of the preceding minutes of the brawl to the league "to attempt to prove that Neymar was the victim of racism."
The video allegedly confirms that Marseille defender Alvaro Gonzalez used a racial slur against Neymar, leading to an on-pitch brawl that saw the forward being sent off in their 1-0 loss.
Three Brazilian lip-reading experts interviewed by Globo TV Sunday, agreed that Gonzalez had called Neymar "mono", "monkey" in Spanish, just before the brawl, after watching the footage from French broadcaster Telefoot.

However, other lip-reading experts, notably in Gonzalez's native Spain, have analyzed the same tape and found no evidence the defender used a racial slur.
According to some Spanish media reports, Neymar in fact used a homophobic slur against Gonzalez.
The French league, which suspended Neymar for two matches over the incident, has announced a probe into his accusations, which Gonzalez denies.
