Sparked by James Troisi, Western Sydney Wanderers have surged into the A-League's top six with a spectacular 5-0 home win over fellow finals hopefuls Western United.
Wanderers, who started Saturday's match at Bankwest Stadium in eighth spot, behind United on goal difference, scored two in the first half and three more in the second, in their most complete and impressive performance of an inconsistent campaign.
Western Sydney have recorded back-to-back wins, while United - who travelled on the day of the game thanks to concerns over Sydney's recent COVID-19 cases - are winless in their last three and continue to struggle away from home.
Troisi opened the scoring with a fine 19th minute solo effort, charging forward from close to halfway and lashing a fierce shot past United goalkeeper Ryan Scott from just outside the area, and was involved in the build up for Wanderers' next three.
Defender Ziggy Gordon doubled their lead from a 36th minute Troisi corner to reward Wanderers for a dominant first half in which they had 14 shots to one and registered all of the half's six attempts on target.
Western Sydney piled on the agony for the visitors in the second half.
Bruce Kamau turned the ball home in the 57th minute before Western United substitute Dylan Pierias scored an own goal nine minutes later to make it four.
Substitute Bernie Ibini blasted the ball home from close range just before the end to cap a wonderful night for the Wanderers, while United conceded five for the first time their short history.
United brought talisman Alessandro Diamanti off the bench In the second half and showed more intent than in the first 45 minutes but were unable to force any sort of breakthrough.
It was a desperately needed win for Wanderers, who knocked Brisbane out of sixth, although the Roar have three games in hand and are only a point behind.
Western United sit eighth, three points behind having played one game fewer than Western Sydney but now with an inferior goal difference.
