A-League clubs could soon be punished for the actions of their fans, with Football Federation Australia exploring the prospect of deducting competition points from clubs whose supporters repeatedly misbehave as part of its crackdown on anti-social fan behaviour.

After a public brawl in Melbourne's CBD on Saturday afternoon between fans of Western Sydney Wanderers and Melbourne Victory led to two arrests and left up to four people needing medical treatment, the FFA is preparing to adopt the most severe measures in its power in an attempt to ensure there is no repeat.

This means clubs could be held accountable for the behaviour of their supporter groups, with repeat acts of violence and other anti-social behaviour resulting in a deduction of A-League competition points as well as suspended points deductions.

A-League head Damien De Bohun confirmed that proposed strict penalties with an effect on results remained a real possibility as a means to deter negative fan behaviour and, if implemented, could come into effect within a matter of weeks.
