Real Madrid's Kylian Mbappé claims that Benfica's Gianluca Prestianni verbally attacked Vinícius Júnior.
"He started talking badly; it's not acceptable, but that happens in football. Then he put the shirt here (over his mouth) to say 'Vini is a monkey' five times," Mbappé told El Chiringuito.
The Argentine Prestianni denies the allegations:
"I want to clarify that I did not at any time direct racist insults at Vinícius Júnior, who unfortunately misunderstood what he thought he heard," he wrote on Instagram.
The European Football Association, UEFA, will investigate the allegations, the association said in a press release.
