GREATER Western Sydney isn't concerned about playing at Optus Stadium for the first time, and might look to get some tips from some former Giants in a bid to topple West Coast on Sunday.

GWS and the Eagles clash in the final game of round 16, and with both teams on very different ends of the form scale, the result has massive top-eight implications.

The home side is clinging to third spot by percentage only despite winning 10 games in a row earlier this year, while the Giants have stormed into sixth on the ladder on the back of their fourth win in a row last week.

Giants' co-captain Phil Davis said a training run the day before the match will help his team get a read on the new stadium, but they might also call some old mates for some local knowledge.

Dockers defender Nathan Wilson was an original Giant before he went back to Western Australia during last year's NAB AFL trade period, while forward Cam McCarthy and runner Tendai Mzungu are also former GWS players.

"We're pretty fortunate that our players believe that if it's got four posts at each end and some white paint around it, it's pretty similar (to other grounds)," Davis said on Tuesday.

"I'm sure that there's certain aspects that are unique to it, but fortunately we've got a few good Fremantle connections that we might be able to use.

"I know Fremantle like seeing West Coast lose, so that could work to our advantage."

Ahead of a clash with the Eagles, Davis would normally be hard at work studying his dossier of notes on star forwards Josh Kennedy and Jack Darling, but with the pair both injured and already ruled out of Sunday's clash, the GWS co-captain and his defence face an unfamiliar-looking outfit this week.

The Giants' past four matches have been extremely impressive, with Josh Kelly making a stunning return from a groin injury, and the likes of fellow midfield guns Callan Ward, Stephen Coniglio and Jacob Hopper all in sublime touch.

But the team's backline group, led by Davis, Nick Haynes, draftee Sam Taylor and Lachie Whitfield, has been a dependable unit all season, and has been significant over the past month.

"I must admit the back six or seven have been in pretty good form for most of the year, and some of the numbers we judge ourselves on have been pretty good even during that four-week period (of losses)," Davis said.

"We've got some really good depth in that area and some of the boys are in really good form."

Whitfield, who was switched to half back after an injury to Zac Williams (Achilles) over summer, is back to his hard-running best after a mid-season lull, and has averaged 28.2 possessions per game in that time.

"He's obviously an incredible player in terms of his ability to work (up and down the ground), his skills are exceptional and his courage is something that's very much underrated," Davis said.

"He does great work around stoppages as well, but he links up and his ability to connect the backs to the forwards is probably his greatest contribution.

"He's someone that probably doesn't get the recognition he deserves, but let's keep him under the radar, thanks."
