Vinicius scored the only goal in Real Madrid's 1-0 win against Benfica but was booked for his celebration. The Brazilian reported alleged racist abuse from Benfica winger Gianluca Prestianni, causing a 10-minute match halt. Uefa have opened an investigation into the claims, which Prestianni denies.
After the match, Mourinho - who was sent off - said Vinicius had been "disrespectful" and claimed Benfica is not a racist club. McCarthy, who won the Champions League under Mourinho at Porto in 2004, said the Portuguese made a "mistake" with his comments, calling it an "emotional decision" and hoping he'll apologize. Vinicius later posted on Instagram: "Racists are, above all, cowards."
