Real Zaragoza face sanctions after a Levante player was subjected to racist abuse during their Primera Liga match on Sunday.
Referee Fernando Teixeira Vitienes has confirmed in his match report that he heard monkey chants being directed at a Levante player.
“I asked the local match delegate to apply the protocol (to make an announcement over the PA system asking fans to stop) and did not hear the sounds again,” he said.
Two seasons ago Barcelona’s Cameroon striker Samuel Eto’o was greeted by monkey chants and had peanuts thrown at him by Zaragoza fans.
In February Real Betis’s Brazilian striker Robert was racially abused and later in the same month Eto’o was again the victim of racist chants.
The Spanish Football Federation (RFEF), who had previously fined Zaragoza 600 euros, imposed a 9,000 euro fine on the club, after the second Eto’o incident.
A week ago the government-run Anti-violence commission, which is looking to clamp down on racism, asked the RFEF to investigate racist chants from the crowd in the Primera Liga match between Celta Vigo and Barcelona.
