Western Sydney Wanderers chief executive Lyall Gorman is upset his fledging A-League club is being dragged into the discussions over hooligan problems in the game.
An incident at a pre-season match between Wanderers and Sydney United received widespread media coverage and came just days after an altercation among fans at Sydney FC's trial match in Campbelltown.
Despite the problems being restricted to United fans after a member of the former National Soccer League (NSL) club's support threw a flare onto the pitch, Wanderers is caught up in the debate.
Gorman said criticism of the club, or even linking it with the unsightly images from last week, is mystifying.
Wanderers' support group, known as the Red and Black Bloc, had already moved to distance itself from the troubles against Sydney United and was receiving praise from police and Football Federation Australia for its behaviour at the club's pre-season matches.
"It's disappointing that we're being criticised for the actions of one mug who decided to throw a firecracker who wasn't tied to the club," Gorman said.
"Wanderers fans, as a supporters group, have been totally on base with their behaviour and attitude.
"There's no issue we need to worry about."
Gorman said A-League regulations prevent fans flying flags or banners with nationalistic links and Wanderers wouldn't need to make any extra steps to stop its fans.
"We're not going to be making any particular stance as a club, we'll be enforcing the same rules as every A-League club," he said.
Gorman added there is no need to alter the club's pre-season campaign, which continues on Tuesday night with a match against Brisbane Wolves in Queensland.
"Why would we change our pre-season? That gives power to people who have no right to it," he said.
"We're going ahead as normal and have no reason to change our plans."
Sydney FC confirmed the signing of A-League championship winning defender Pedj Bojic for two years and Brazilian centre half Tiago Calvano for next season.
