GREATER Western Sydney coach Leon Cameron says the key to victory will be to stop star West Coast forwards Josh Kennedy and Mark LeCras, as the Giants chase their first win in Perth on Saturday night.

Kennedy, in particular, has tortured the Giants in their short history - most notably in round eight last season when he kicked 11 goals straight in the Eagles' 111-point win at Domain Stadium.

In three matches against GWS, Kennedy has 18 goals and has taken 21 marks, while LeCras has hauls of four and three goals in two games against the Giants.

"Kennedy's a fantastic player. It's not just his ability to kick goals, his pressure is enormous and he plays almost 100 per cent of game time, so he's a very fit big man," Cameron said on Wednesday.

"Add LeCras, who is a quality player and has been for ten years, and it's a really, really good forward line."

Kennedy leads the Coleman Medal race in 2015 with 16 goals, and has been dominant in the Eagles' two wins this year.

He kicked 10 goals and dragged in nine marks against Carlton in round two and, although wasteful last week against the Brisbane Lions, still managed 3.5 and took eight marks.

Former Lion Joel Patfull has added valuable experience to the Giants' backline this season and could get the job on LeCras, with Phil Davis likely to get first crack at Kennedy.

"They're a pretty dangerous forward line. They've got a lot of guys up there who can kick pretty big scores," Patfull said.

"We've got a pretty consistent back six or seven who have played the first four weeks, and we think we've been pretty solid. It's definitely going to be a big test but its something that we're looking forward to."

While Cameron has West Coast firmly in his sights, he weighed in on the controversial incident from Adelaide last weekend involving former mentor, Hawthorn coach Alastair Clarkson.

"The situation obviously looked quite threatening. The situation looked like it might have gotten out of control, but unless you or I are in that situation, it's hard to comment on it," Cameron said.

"I know Clarko's a very proud man and he'd be disappointed that it got out of hand. But in saying that, sometimes you can be pushed to the limit."
