Neymar reportedly picked an argument with Julian Draxler following Paris Saint-Germain’s recent unconvincing results.
According to Le Parisien, the Brazilian was annoyed after the final and accused some of the young players ignoring the more experienced members of the squad.
Neymar was also furious with some of Presnel Kimpembe's comments after the defeat against Nantes, when the 23-year-old asked the rest of his teammates in the dressing room to pay no attention to their coach Thomas Tuchel.
Another incident involving Neymar is alleged to have occurred last week when PSG lost 3-2 to Montpellier thanks to the last minute goal from Souleymane Camara.
Julian Draxler criticised Neymar for his personal jibes. In front of the rest of the dressing room, the former Barcelona attacker took aim at the German: “Who are you to talk to me? You only ever pass the ball backwards.”
