The fourth official, Sebastian Coltescu, referred to the Istanbul Basaksehir assistance coach Pierre Webó as "The black one over there".
TV cameras picked up the dialogue in the run-up to the players abandoning the pitch in protest at racist comments from the fourth official, Sebastian Coltescu, about Istanbul Basaksehir assistant coach Pierre Webó.
Sebastian Coltescu: The black one over there. Go and check who he is. The black one over there, it's not possible to act like that.
Webó: Why did you say black? Why did you say black?
Coltescu: We speak Romanian between us.
Demba Ba, Basaksehir player: You never say ‘this white guy’, you say: ‘these guys.' So, listen to me, why when you mention a black guy do you have to say ‘this black guy?’” why the official said "this black guy."
Mbappé, PSG player: If the fourth official said that, he has to go.
Okan Buruk, Basaksehir coach: He said nothing. Your assistant said black, and you sent him off.
Coltescu: In Romania, black is a reference to the colour of the skin, a black player, and among us we speak Romanian.
Hategan, match referee, to Leonardo, PSG sporting director: We'll take 10 minutes, we'll stop the match and go to the dressing room, because this is a special case. Then we'll carry on, if they want to.
