With fans losing faith and fractures appearing in the team, no side was under more pressure to win this week than the Sky Blues, who fired themselves back into the top six after claiming the three points on Saturday.
Serbian Ranko Despotovic opened the scoring but it was young gun Terry Antonis who impressed.
The 20-year-old came through his baptism of fire with flying colours, scoring in his first match of the season after a long injury layoff and proving he hasn't lost any of his deft touch on the ball with a strong showing in midfield.
Socceroos centre-back Sasa Ognenovski also proved crucial, adding some much-needed steel to the shaky Sydney defence on his debut for the club.
Meanwhile in an A-League first, the 11,160-strong crowd were treated to a showdown between two World Cup finalists in Alessandro Del Piero and William Gallas, adding yet another layer to the encounter.
It was a more composed, positive-looking Sydney that took to the field this week with the embattled side desperate to salvage their season and restore faith among their disgruntled fans.
Last week some supporters unfurled banners calling for coach Frank Farina's head and that of chairman Scott Barlow and chief executive Tony Pignata.
This week they delivered another clear message: "SFC board we want action not words".
And while the club management will meet with fans in another members forum on Tuesday, the players went some way to pacifying them on Saturday.
Del Piero created chances in the opening stages and it finally paid off in the 17th minute with Despotovic pouncing on a through-ball from the Italian to put the hosts ahead with his sixth goal in 12 games.
Sky Blues keeper Janjetovic almost cancelled the goal out moments later with the ball hitting the woodwork in a clearance gone wrong.
Perth looked like equalising just after the break creating several chances while Chris Harold had Janjetovic on guard, firing from long-range but going just over.
It was Sydney who scored next, however, with Antonis beautifully weaving past the Glory defence to double the Sky Blues in the 65th minute.
But the celebrations were short-lived with Rostyn Griffiths getting on the end of a Nebojsa Marinkovic ball to head home for Glory just two minutes later.
Glory kept pressing as the Sky Blues were reduced to 10 men in the dying minutes after Aaron Calver was sent off in collecting his second yellow card.
