GREATER Western Sydney coach Leon Cameron denies his club has a discipline problem, but has told hot-headed All Australian stars Toby Greene and Heath Shaw to control their aggression.

Greene and Shaw were involved in two incidents during last week's win over the Swans which have taken some of the focus off the club's first blockbuster Friday night game in Canberra.

The Match Review Panel cleared Greene for his headbutt on Sydney's Isaac Heeney, and Shaw came under criticism for an inappropriate sledge on Tom Papley, for which he later apologised.

Cameron revealed he had spoken to both men about their onfield behavior over the past two weeks, in particular Greene, who has come close to attracting the attention of the MRP on more than one occasion.

"He's such a competitor (but) he's got to make sure that in the moment he's got to be able to control that aggression," Cameron said.

"We don't want to lose any players to suspension, let alone guys with the quality of Toby Greene. He's better off playing than sitting on the sidelines, and he knows he has to constantly work on that.

"The one thing that I will say is that I love the way he goes about it, but he does know that when that tipping point comes, he's got to be able to take a deep breath and move onto the next contest."

Cameron said veteran defender Shaw also knew that his competitiveness could take him over the edge.

"I was rapt with the way he handled the situation last Saturday night [following the Papley seldge]," he said.

"Heath is a knockabout (guy) but he was genuinely remorseful and upset, and was right on the front foot about it, and we move on."

Cameron said he had kept the conversation confined to his fiery stars and had not felt the need to address the team.

"These good quality sides like the Dogs, Hawthorn, Geelong, and Sydney, they play on the edge, and that's probably what we've learnt as a young club," he said.

"When we were playing them in year two, three, and four, these sides would play on edge, and make sure that their competitive nature was always at a premium, but they know not to tip over the line.

"Sometimes our players tip over, but as long as they keep learning and understanding that you're better off playing every weekend than sitting on the sidelines.

"It's not a group thing, it's been a couple of individuals and they'll be fine."
