Glory's Foxtel Y-League team suffered their fourth single-goal defeat of the season as they were pipped 3-2 by Melbourne Victory at Dorrien Gardens on Sunday.
Jake Brimmer's penalty and a fine solo effort from Henry Hore handed the hosts the lead early in the second half after Pierce Waring had opened the scoring for Victory before the break.
But Nicholas Sette and Nuh Sehavdic struck twice in quick succession to secure the three points for the visitors and leave Glory's Head Coach John Gibson deeply frustrated.
"This is the worst performance we've had for a year," he said."It wasn't good enough and that performance doesn't represent Perth Glory Football Club.
"We beat ourselves today - we gifted them three very soft goals and weren't clinical in the front third.
"It was a really frustrating day, but we must give credit to Melbourne Victory who were ruthless and capitalised upon their opportunities.
"The most disappointing thing is that our work rate and attitude were poor. These are things that are non-negotiable for this group, something that goes away from our team ethos."
With both Brimmer and Nick Feely having been drafted in from the Hyundai A-League squad, Gibson's side started brightly, Walter Scott’s shot forcing a save from Matthew Sutton in the Victory goal before Yagoub Mustafa fired over the top moments later.
Victory were on the back foot as Glory looked for the opener, but against the run of play it was the visitors who took the lead on the half-hour, Waring turning his marker in the penalty area and firing low past Feely.
Glory should have levelled two minutes into the second half when Mustafa raced down the right and crossed to Chok Dau, but the striker headed over from close range.
The lively start to the second half then continued when referee Shane Skinner pointed to the spot after he spotted a handball and Brimmer converted from the spot to make it 1-1.
And two minutes later, Glory hit the front when Hore picked the ball up in the middle of the park, raced past his marker and capped his fine run with a clinical finish.
Sette and Sehadvic duly netted for the visitors in quick succession, however, leaving Glory chasing the game which they certainly did in the final 20 minutes.
Sutton was forced to produce a stunning save to thwart substitute Michael McDougall’s half-volley and then also denied Ollie Annis before Riley Warland headed inches over from a corner.
It wasn't quite to be for the men in purple, however, much to the disappointment of goalscorer Hore.
“We let ourselves down today,” he said.“We made silly errors and it cost us, it wasn’t good enough.”
“I scored, but it doesn’t matter because we didn’t get the result we wanted. We are better than that and we have to take a good look at ourselves and put it right in the next game.”
Glory return to action on Thursday 28th December with an away trip to Adelaide United.
