Neymar has hit out at referee Bjorn Kuipers and accused him of saying something "disrespectful" to him during Paris Saint-Germain's 1-1 draw at Napoli on Tuesday.
The official gave Neymar an injury-time yellow card for dissent at the Stadio San Paolo, and the Brazilian complained about him in the mixed zone after the match.
"The referee told me something he should not have. It was disrespectful. I do not want to repeat what he said to me. However, somebody high up should do something. He cannot be as disrespectful as he was with me.
