A-League club Melbourne Heart are confident they have identified the supporter who launched an attack on a Western Sydney Wanderers fan at AAMI Stadium.
Heart chief executive Scott Munn told AAP the club believes it knows the identity of the man whose face was clearly caught on Fox Sports TV coverage as he landed a king hit on the bare-chested Wanderers fan on Saturday night.
"We are reasonably comfortable we know who the person is and all action will be taken to provide his identity to the police," Mr Munn said.
Mr Munn stressed the man was not a member of the club.
"His actions were not appropriate and we don't accept it - it was absolutely abhorrent," Mr Munn said.
Victoria Police said that they are aware of the vicious assault, and are working with Melbourne Heart, but say so far no one involved has reported it to police.
Melbourne Crime Investigation Unit detectives are searching for two men who were assaulted during an A League soccer game at AAMI Park on Saturday, March 16.
Investigators have been told the assault took place in the northern stand about 7.50pm.
Officers believe a man, who was not wearing any supporter colours, entered the Sydney supporter group area and assaulted the two unknown males.
Police are keen to speak to these two men, who are believed to be Sydney fans.
A number of persons of interest have been identified as part of the investigation.
At this stage, no charges have been laid.
