UEFA are closely monitoring tensions between Vinícius Júnior and Gianluca Prestianni ahead of the second leg clash between Real Madrid CF and S.L. Benfica.
The situation escalated following the first leg, where Prestianni allegedly directed a racially abusive remark toward Vinícius Júnior during a heated exchange on the pitch. The incident reportedly occurred after a series of confrontations between the two players, with tempers flaring late in the match. Teammates and match officials were forced to intervene as the argument intensified.
Cadena SER reports that UEFA are internally concerned about the possibility of further tension during the return fixture, including fears that the players may refuse to shake hands during the pre match protocol. Such a gesture is viewed by the governing body as symbolically important to the image of European football, and any public refusal would be seen as damaging.
The same report indicates that UEFA have considered disciplinary measures against Prestianni, including the possibility of preventing him from featuring in the second leg. However, imposing an immediate sanction of that nature would be highly unusual.
UEFA are expected to release an official statement in the coming days to clarify their position and outline any potential action.
