Thomas Tuchel believes it is clear that Neymar has felt the effects of Paris Saint-Germain's recent poor run as the French Football Federation (FFF) opened proceedings against the forward.
PSG have won just one of their past six matches in all competitions, including a Coupe de France final collapse against Rennes after Neymar's goal had put Tuchel's side 2-0 up.
The Brazil international let his emotions get the better of him following the penalty shoot-out defeat last week as he appeared to punch a fan in a scuffle on the way to collect his runners-up medal.
