Western Sydney CEO John Tsatsimas says that the 'cowards' who light flares are not welcome at Wanderers' games.

Tsatsimas spoke to the media on Wednesday and while he admitted he was disappointed at the sanctions towards the club, called for a united stand against flares and anti-social behaviour.

"I appeal to those who have conducted themselves questionably to comply and behave as you would in any other part of society," Tsatsimas said.

"For those who will not comply, do not come back. You are not welcome. Stop using our club as a promotional vehicle for your own purposes.

"For the rest of our fans, do not encourage them. We do not want cowards who let of flares and hide behind anonymity.

"There is an expected mode of behaviour that needs to be displayed on match days. We don't want this to happen. The players, coaching staff and club itself are the ones bearing the consequences."

Tsatsimas backed the club's active supporter group, the RBB, as a whole, ensuring he differentiated between the minority and the large portion of the fans doing the right thing.

“It's unfortunate that those who conduct themselves inappropriately put themselves in that group and it tarnishes that group,” he said.

“The RBB have been nothing but fantastic. We just hope (the minority) are weeded out.”

The Wanderers take on Sydney FC in the Sydney derby in just two weeks time in a typical fiery encounter. But Tsatsimas said he is confident the match will be incident free.

“It's incumbent upon us to make sure it's a safe match. Protocols have been addressed and reviewed," he said.

"It's a collective celebration of football, not 40,000 fans going against one another. This must be the mindset at the derby."
