In the second round of the FIFA World Cup group stage, the match between Turkey and Paraguay is underway, with Paraguay currently leading 1-0. Before the end of the first half, Almiron communicated with his mouth covered, and the referee sent him off after reviewing VAR.
In a Champions League match between Benfica and Real Madrid in February this year, Prestianni communicated with Vinicius with his mouth covered. The content of their conversation is unknown, but Vinicius believed it was a suspected case of racial discrimination, and Prestianni was subsequently suspended, which also caused great controversy.
At the end of April, FIFA passed a proposal. According to the new rule, at the discretion of the event organizer, any player who covers their mouth during a confrontational situation with an opponent may be sent off with a red card. Almiron became the first person to be penalized under this rule.
