Melbourne Victory have been hit with a $50,000 fine and a suspended three competition point deduction for fans’ misbehaviour at Saturday’s Melbourne A-League derby.

The Football Federation Australia (FFA) sanction is for bringing the game into disrepute as a result of seven flares being let off inside and outside AAMI Park, an alleged assault on a TV news crew and missiles thrown at a Melbourne City player and a police officer.

They are the same sanctions FFA imposed on fellow A-League heavyweights Western Sydney Wanderers a week earlier after Wanderers supporters let off 25 flares and detonators at Etihad Stadium during their clash with Melbourne Victory.

Victory’s points sanction is suspended for 12 months and will only be enforced if another ‘serious incident’ occurs, with that decision at the discretion of FFA.

Victory have chosen not to appeal the punishment, instead appealing to their fans to show solidarity.

The club’s four leaders – chairman Anthony Di Pietro, chief executive Ian Robson, coach Kevin Muscat and acting captain Leigh Broxham – shared a stage to make a final pitch to their fans.

“Enough is enough,” Di Pietro said.

“We’ve reached a line in the sand moment … when we ask the true Melbourne Victory fans to stand with us.

“Together we must ensure that anti-social behaviour from a marginal element does not compromise everything that we’re trying to achieve.

“Our message is simple. No more flares. No more anti-social behaviour.”

FFA was similarly forthright in its response.

“The behaviour of a number of Melbourne Victory supporters last Saturday night was deplorable and cast a shadow over what was a fabulous game of A-League football,” FFA CEO David Gallop said.

“It’s staggering that these dangerous incidents happened just days after FFA had applied sanctions to the Western Sydney Wanderers because of the actions of some fans.

“The focus on fan behaviour could not have been more acute.

“If there is any bright note in this situation, it is the refreshing attitude shown by both clubs through their CEOs, coaches and players.

“They are saying enough is enough. As leaders and ambassadors of their clubs, they want to be part of the solution.”

Gallop said FFA took in mitigation the club’s submission, in which it committed to review and enhance safety and security measures at its matches.

“FFA acknowledges Melbourne Victory’s long-standing efforts to manage fan behaviour issues,” he said.
