Arnold and Sydney FC had requested an apology from Wanderers in light of the event through Football Federation Australia.

Wanderers initially refused, with CEO John Tsatsimas speaking on radio in midweek after suspending 14 Members, saying they wouldn't apologise for the actions of a minority of their fans.

However, in a club statement following the finalisation of their review relating to the off-field events at last Saturday's Sydney derby, Wanderers chairman Paul Lederer apologised.

“Unfortunately the events of the last week have overshadowed what we should be celebrating as a fantastic event between Sydney’s two A-League teams,” Lederer said.

“It is with great disappointment that the actions of a minority have prompted fairly stern action to be taken by the Club this week to eradicate anti-social behaviour.

“On behalf of the Western Sydney Wanderers, we apologise to Graham Arnold and his family and to all others who have been offended by the abhorrent actions of a few who are now no longer part of our Club.

“We urge everyone now to come together and celebrate the great event that the Sydney Derby has become and to attend future A-League matches in the right sporting spirit.”
