Kwame Yeboah gave the Wanderers an unlikely lead and when Western Sydney added another through Roly Bonevacia after the break, it looked as if Markus Babbel's side were leaving the west with an incredible upset. 

But half-time introduction Diego Castro sparked Glory into life, and even though the Wanderers struck a third through Abraham Majok - Babbel's counter-attacking ploys working wonders - Perth drew stronger as the match wore on.

In a stark reflection of the Wanderers' current defensive issues and mental fragility, Perth scored three unanswered goals within 10 minutes, through Ivan Franjic, Andy Keogh and a Juande penalty respectively, to round out 4-3 winners and send HBF Park into pandamonium. 

There were controversies over two of Perth's goals however, with an offside Jason Davidson adjudged not to be effecting the play during Keogh's equaliser, before Keogh appeared to go down very lightly to win Juande's penalty.

It was the second time in a few days that an A-League cellar-dweller had shown incredible fight, just to remarkably collapse in the second half.

But with the status quo maintained - Perth move six points clear at the top of the table, the Wanderers fall to their eighth loss in 13 games to remain eighth - the pressure can only increase on the Wanderers' perenially-cool German coach.
