There was an incident with Cavani talking to one of his mates from Uruguay on Insta and using a term like that too.Dubious tackle from a PSG player and the fourth official says in Romanian, referring to the player, 'That black ('negru') one there, something like that is not acceptable' - Romanians are more comfortable denoting people by skin colour so there is a cultural mismatch. 'Negru' literally means 'black' and is not equivalent to the n-word.
Maybe that's for the best though. I remember after I heard and I went to check out the Guardian report and what people were saying and one of the first comments was something like "I can't believe that substitution he made against Tottenham that time, definitely cost us three points.I was sad to hear about that. Nothing really to say, but just... RIP I guess.
