UEFA has charged Barcelona midfielder Sergio Busquets with racially insulting Real Madrid defender Marcelo during the Champions League semifinals.
UEFA says its disciplinary panel will hear the case on Sunday.
Busquets is alleged to have violated UEFA's discrimination rules ''by directing racist abuse towards'' Marcelo, who is black. Marcelo says that Busquest called him a ''monkey'' during a rough first-leg match on April 27 in Madrid.
UEFA said it took statements from Marcelo and Madrid and used video evidence of a moment when the two players clashed.
Barcelona won that game 2-0 and then tied 1-1 in Barcelona to advance to the final against Manchester United. Busquets could be suspended for the May 28 match at Wembley Stadium in London.
The rulebook states that ''anyone who insults the human dignity of a person or group of persons, by whatever means, including on grounds of color'' shall be banned for five matches.
European soccer's governing body had initially dismissed the racial abuse claim, along with Madrid's request that Barcelona's Dani Alves, Pedro Rodriguez and Busquets be sanctioned for feigning injuries.
Madrid contested those rulings and a UEFA appeals body will hear the case next Monday.
