Real Madrid defender Antonio Rudiger accused the Pachuca player Gustavo Cabral of racial abuse of him during the H Clash group on Sunday at the FIFA Club World Cup.
A visible smoking rudiger reacted to something that Cabral told him during an argument in a stopping time of Madrid's 3-1 victory by submitting a complaint to the Brazilian referee Ramon Abatti Abel.
Abatti did not give a card to Cabral, because he had apparently heard nothing unwanted.
Moments later, however, the referee was seen that he crossed his arms to make FIFA's 'no racism gesture', suggesting that the incident will be further investigated.
Madrid manager Xabi Alonso then said in his press conference after the game: 'Racist insult to Rudiger? That is a bit more rudiger said, and we believe him.
'Now FIFA is investigating. It is unacceptable. '
