Barcelona midfielder Sergio Busquets has denied allegations that he racially abused Real Madrid's Marcelo in the first-leg of the club's Champions League semi-final on April 27.
The player was speaking after UEFA announced that they had opened up a disciplinary case against Busquets.
Madrid accused the Barcelona midfielder of calling the Brazilian left-back a "mono" (monkey), and provided video evidence which they claim supports their allegation
However, the secretary for the Barcelona board, Toni Freixa has confirmed that Busquets denies the accusations, with Busquets admitting he said Marcelo had a "a lot of nerve".
"When they [Real Madrid] showed images from Youtube [on their site], we spoke to the player and he told us the accusations are false, and what he said was [Marcelo had] 'some nerve.'", Freixa told Barca TV.
Barcelona will submit their arguments to UEFA on Friday although Freixa is concerned about the outcome.
"We are at an early stage of what could be a great injustice. We hope that UEFA maintain a serious approach and continue, as they have done, to protect the innocent," he added.
if found guilty, Busquets could be suspended from the Champions League final against Manchester United at Wembley on May 28.
