The Government of Portugal has announced an independent investigation into allegations of racism involving SL Benfica winger Gianluca Prestianni during a UEFA Champions League match.

The 20-year-old Argentine was accused by Vinícius Júnior of making racist remarks during Benfica’s knockout phase play-off clash with Real Madrid CF at the Estádio da Luz on February 17.

The incident occurred about 10 minutes into the second half, shortly after Vinícius scored and celebrated near the home supporters. Tensions rose between players, prompting match officials to briefly halt play in line with UEFA protocols.

Vinícius later approached the referee to report alleged remarks made by Prestianni, who was seen covering his mouth with his shirt.

UEFA confirmed that it has opened an investigation, saying official match reports were under review and that disciplinary procedures would follow if necessary.

In a post-match statement, Vinícius condemned racism and criticised what he described as weak enforcement of existing protocols. He also questioned why he received a yellow card for his goal celebration.

Prestianni, however, denied the allegation in a social media post, insisting he did not direct any racist insults at the Brazilian forward and saying his words were misunderstood. He also said he regretted threats he received following the incident.

Portugal’s Authority for the Prevention and Fight against Violence in Sport, Authority for the Prevention and Fight against Violence in Sport (APCVD), said it has launched administrative sanction proceedings to establish the facts.

In a statement, the body said it was acting on media reports and would seek to determine whether a racist attack occurred during the UEFA-organised fixture.

The case has added to growing concerns over racism in European football and the effectiveness of existing disciplinary measures. Authorities said findings from the investigation would guide any possible sanctions.

Both UEFA and Portuguese officials said further updates would be provided as inquiries continue.
