Sydney FC midfielder Ali Abbas has accused unnamed Western Sydney Wanderers players of racially, religiously and culturally abusing him during Saturday's A-League match.
The Iraq-born player told a television interviewer after his side's 3-1 win that "we are not here to attack religion or culture; we are here to play football ... I come from a different country, I respect everyone here. I should get it back."
Sydney FC coach Frank Farina and his Wanderers counterpart Tony Popovic said they were not aware of any incidents.
On Sunday, Football Federation Australia said in a statement that Sydney FC indicated they would lodge a formal complaint, and that the claims would be investigated by a league tribunal or through mediation.
Sydney FC chief executive Tony Pignata said Abbas "was obviously very unhappy after the game ... with what happened."
