Sydney FC have thrashed the Wellington Phoenix 7-1 to all but end the visitors' playoff hopes in Sydney.
Italian great Alessandro Del Piero scored four times including a dubious penalty to inspire Sydney to their biggest-ever win, while it's the Phoenix's worst-ever loss.
The 38-year-old Del Piero struck the competition's second-fastest hat-trick in the first half and added another brilliant goal after half-time.
There was more than a touch of fortune to the penalty as Andrew Durante was harshly adjudged to have fouled Jason Culina inside the box and Del Piero made no mistake with the penalty.
The Phoenix defender Ben Sigmund bagged a consolation goal in the 79th minute..
The performance moved Sydney to the cusp of the top six as they registered back-to-back wins for only the second time in a turbulent season, while the Phoenix sit dead last on the A-League ladder after four straight losses, equalling their worst losing streak from October 2007.
And they could be three points adrift after second-last placed Brisbane's home game on Sunday against Western Sydney Wanderers.
The Phoenix's previous biggest loss was a 6-1 defeat to Adelaide in December 2008.
Elsewhere, 10-man Perth Glory lost 1-0 at home to Melbourne Victory - the only goal an own goal - while leaders Central Coast Mariners drew 0-0 at home to the Newcastle Jets.
