Vinicius alleged Prestianni called him a 'monkey' during Tuesday's Champions League play-off first leg, causing a 10-minute stoppage. The 20-year-old Argentine denies the claim, covering his mouth as he appeared to speak.
Real Madrid teammate Kylian Mbappe demanded Prestianni's exclusion from the competition, stating, 'This guy doesn't deserve to play in the Champions League again.' Vinicius remains a frequent target of racism in Spanish football.
