Perth marquee man Mile Sterjovski has urged his team-mates to exploit an injury-depleted Sydney line-up in Sunday's home clash as the Glory attempt to shore up a top-six A-League berth.
Ladder-leaders Sydney enter the clash minus in-form striker Alex Brosque, who picked up a groin injury while in camp with the Socceroos, and defender Sebastian Ryall, who has been ruled out for six weeks with a knee injury.
To add to Sydney's woes, centre back Simon Colosimo must serve a one-week suspension, forcing the club to sign Hayden Foxe on a six-week deal despite the former Glory defender having not played for more than a year.
Foxe, who played for Aston Villa, Leeds and Portsmouth during a glittering but injury-plagued career, made the trip west and is likely to feature against the Glory.
Sterjovski, travel-weary but upbeat following his 60-minute starting role in Australia's 2-2 draw with Kuwait, said the Glory must capitalise on their weakened opponent.
"Alex is a great player and I'm sure Sydney are going to miss him so we've got to take that chance," Sterjovski said.
"They are missing a couple of good players so ... it's a good chance to get the ball rolling again for us."
Perth welcomes back striker Branko Jelic from an ankle injury but Victor Sikora (thigh) and Wayne Srhoj (knee) will miss at least another week.
Glory skipper Jacob Burns said his team must display the same sort of form shown in last round's 4-0 thumping of Newcastle, which lifted the Glory back into the top six.
"Sydney are up the top of the table so we've got to be on our game but I think if we play like we did against Newcastle there's no reason why we can't get the three points," Burns said.
Perth defeated Sydney 2-0 at ME Bank Stadium in round 15 and Glory coach Dave Mitchell remained wary of a side gunning for revenge.
"They're a very well organised side and they're not top of the league by fluke," Mitchell said.
"They're consistently good and that's one of their strengths.
"I don't think it's a team of individual stars but they are a very good team and especially dangerous on the counter attack."
