He bounced high in the air to meet a terrific cross from Troisi to score his first, while for his second, he latched onto a long diagonal ball and easily outpointed Glory rookie Luke Bodnar in a one-on-one battle.
The fringe Socceroo nearly had a hat-trick but couldn’t find an empty net from an acute angle. He was withdrawn in the 67th minute to rapturous applause at Bankwest Stadium.
The Wanderers were grateful for the VAR earlier in the week when Tomer Hemed was denied a dramatic injury-time equaliser for Wellington Phoenix by a controversially tight offside decision.
It wasn’t all bad for them on Friday night. VAR operator Craig Zetter awarded Troisi his 50th-minute goal, which was initially disallowed as the linesman wrongly flagged Bernie Ibini for a breach in build-up play, as replays proved.
Ibini himself could have had a hat-trick. He had an early attempt saved by Liam Reddy, and then saw two other goals disallowed for marginal offsides, one of which involved the VAR.
Daniel Wilmering was also denied a goal by the VAR, but all three were, technically, offside – at least according to the line drawn by the technology.
Wanderers fans, however, will argue that two of them were not “clear and obvious” errors and shouldn’t have involved the VAR, and they may have a fair point.
On this occasion, it didn’t cost them, as Robinson’s men were able to expose the Glory’s defensive frailties with consummate ease.
The visitors had a couple of long-range lashes at goal in the opening minutes and only started troubling Western Sydney again when the result was already locked away.
In the end, the final margin was flattering to them, and Perth now have the competition’s second-worst defensive record – better only than Melbourne Victory, who have played one more match.
“I think we definitely lacked intensity, but at the moment we’re carrying our experience in three, four or five senior guys,” coach Richard Garcia said.
“From there we’re counting on these young guys to be consistent and at the moment they’re not consistent. It’s always the case when you’ve got younger players, it’s part of their process of learning and them getting better, so there’s going to be hiccups along the way. We’ve just got to make sure we build off this and make sure we don’t make the same mistakes again.”
