Alessandro Del Piero scored the winner in Sydney FC's first victory of the Australian A-League season while elsewhere former England international Emile Heskey had a hand in both of his side's goals.
Juventus legend Del Piero scored his second goal in as many games in a 1-0 derby win over Western Sydney Wanderers on Saturday in front of a delighted 19,000-plus crowd.
The Italian World Cup winner found the net after retaking a penalty in the 54th minute, to end Sydney's losing start to the new season.
Del Piero, 37, was ordered to retake a successful first spot kick and had his second saved by keeper Ante Covic, only to knock in the rebound.
Sydney chief executive Tony Pignata, who flew to Italy to secure Del Piero's signature, said he was thrilled with the Italian great's impact in Australia.
"I knew he'd be good but three games in and he's starred in all three games," Pignata said.
"He's adapted to the A-League quickly and he's been a revelation off the field as well.
"Even last night leaving the ground, there was fifty to sixty people waiting for him and he took his time and took photos and signed autographs. He's just brilliant."
Sydney FC, who averaged crowds of under 12,000 before Del Piero signed, are now eighth in the 10-team league.
Heskey's Newcastle Jets are one of three joint leaders after his second goal of the season in a 2-1 win over Central Coast Mariners.
Heskey played a role in both goals, earning the Jets a fourth-minute penalty when he was brought down in the box for Ryan Griffiths to convert and side-footing James Virgili's cross home from close range.
Adelaide United lost their unbeaten start, going down 2-1 at Melbourne Victory, while Perth Glory made it a three-way share of the lead with a 2-0 win over Melbourne Heart at home on Sunday.
Champions Brisbane Roar earned a point through Albanian striker Besart Berisha in Wellington with a 1-1 draw against Phoenix on Sunday.
