Football Federation Australia has issued Melbourne Victory a ‘show cause’ notice after a number of incidents involving the A-League club’s fans at the Melbourne Derby on Saturday.

The club has until 5:00pm (AEDT) on Wednesday to explain why it should not be sanctioned for bringing the game into disrepute.

Seven flares were lit before and two during the match, while some spectators also threw bottles at Melbourne City goalkeeper Thomas Sorensen after a controversially disallowed goal denied Victory a win.

Police also said a TV reporter and cameraman were assaulted on the way into the stadium and a total 20 people were evicted.

The reigning champions face a range of potential sanctions including a fine and suspended points deduction, both of which the Wanderers copped last week for their outrageous pyrotechnics display at Docklands.

FFA chief executive David Gallop said the actions of some Victory fans had “cast a shadow on football”.

“The timing of these incidents has shocked many people given the acute focus on these issues,” he said.

“No one could have missed the fact that FFA, our clubs, players and coaches have been explicitly clear in our condemnation of actions over the last week around the ignition of flares. We must continue to hold the safety and enjoyment of true football fans at the heart of our decisions.

“The reaction of a section of Melbourne Victory fans, players and coaches on Saturday night has again sent a clear message that this minority is not welcome.”

FFA is still working with police and AAMI Park security to find specific offending fans and ensure they are subject to the proper banning procedures, which will be announced later on Tuesday.

Coach Kevin Muscat said he was “fed up” with the offending individuals’ “mindless acts” and Melbourne City mentor John Van ‘t Schip echoed his sentiments after the game.

Before the derby, frustrated Victoria Police warned they would shut down games if fans continued to cause trouble.

On Sunday, a police spokesman said the fact that the majority of Victory supporters booed at the bad behaviour showed the problem was clearly restricted to a minority of supporters.

“We’ll continue to have the game running, but as a safety issue … if that continues, the game is going to stop,” he said.
