THE FINALS equation isn't on Leon Cameron's mind just yet.

Greater Western Sydney is at risk of a third successive defeat since the resumption of competition when it meets an unbeaten Collingwood side on Friday night, but the Giants coach insists it is too early to be speaking of the encounter as a defining battle.

A loss to the Pies would equate to a dreaded 1-3 start to the season, subsequently forcing an uphill battle for last year's beaten Grand Finalists to again qualify for the top-eight following back-to-back defeats to North Melbourne and the Western Bulldogs.

However, Cameron has stressed that the only focus for his side throughout the week has been Friday night's pivotal clash at Giants Stadium. Not the potential repercussions of another loss.

"I understand there's going to be lots of ebbs and flows throughout the year," Cameron said.

"There are a few sides who have probably started a bit slower than what they would've liked and we're one of them. But equally there are going to be lots of twists and turns.

"Whatever happens after round four, I'm not really worried about at the moment. Round four is our clear focus and that is to take it up to the Pies, who clearly sit up near the top of the ladder.

THE LADDER Where is your team sitting?

"We need to play a brand of footy that we played last year. We need to find that and find it quickly. The scoreboard will take care of itself, it's the actions that we're looking for on the weekend."

The Giants will be bolstered by the return to full fitness of three All-Australians for Friday night's clash, with Toby Greene (knee soreness), Josh Kelly (calf tightness) and Lachie Whitfield (concussion) all passing tests earlier this week.

"Lachie has passed his cognitive state test, so he'll be expected to play," Cameron said.

"Toby has as well, and so has Josh. Those guys will be named in the squad.

"Clearly, Toby and Josh want to get their seasons kicked off again. They were disappointed in their own performances in the round two game and then they didn't have that opportunity to play last week. Lachie was out at quarter time because of the concussion.

"It's like anything. It doesn't matter whether you've been an All-Australian, whether you're the captain of the footy club or a rookie … it doesn't matter. You want your 22 players displaying the manner and the footy that you want to show every weekend.

"We put our hand up, it wasn't there for parts of the game last weekend. Having those guys in definitely injects a lot of confidence, but equally our guys in there need to make sure that the brand of footy is played in a really good manner."
