WESTERN Sydney Wanderers have claimed their first A-League victory of the season, outclassing Sydney FC 2-0 in a heated derby clash at Allianz Stadium in Sydney. The Sky Blues, who last week capitulated against Brisbane after Alessandro Del Piero left the pitch with a calf complaint, again appeared rudderless tonight without their injured skipper in suffering their first home loss in nine matches. The Wanderers' own Italian import, Iacopo La Rocca, opened the scoring early with Shinji Ono rounding out the goals in front of a record crowd of 40,388, topping Sydney's previous mark for a regular-season match. With both teams locked at a win apiece and a draw in three previous derbies, the Wanderers can now claim bragging rights. Serbian recruit Nikola Petkovic provided the only glimmer of hope for the hosts, with his long-range missile that hit the crossbar 10 minutes before the break their best chance of the match. It was Sydney's defending from set-pieces that was their undoing in their 6-0 drubbing by the Roar and they were guilty of making the same mistakes. La Rocca, replacing the injured Aaron Mooy (concussion) in the starting line-up, broke the deadlock in the 11th minute off an Ono corner as the Rome-born journeyman was barely challenged by the Sky Blues' backline. Youssouf Hersi, who was a constant menace down the right for Sydney, looked to have doubled the advantage moments later but was ruled offside. The second goal was again the result of poor defending with Tiago Calvano and Sebastian Ryall unable to dispossess Ono, who off-balance managed to slot the ball home for a 2-0 lead in the 26th minute. Nicky Carle, who wore the Sydney FC captain's armband in place of Del Piero, was also tasked with providing the creative spark in the Italian's place but took until the 84th minute to have his first shot on target. And while starting the second half strongly with speedy Panamanian Yairo Yau replacing Mitchell Mallia in attack, Sydney just were not able to match the Wanderers' firepower. In a further blow to Sydney, utility Rhyan Grant, who left the field with a knee injury just before the break, could be sidelined for weeks with the injury suspected to be serious. "I thought the effort was there," Sydney coach Frank Farina said. ``We made two mistakes, and again one was after a set piece, it was just poor marking . . . and we got punished for both. Two-nil makes it hard but they kept on trying. We just lacked a bit if creativity upfront. Despite their obvious lack of spark in the front third, Farina said he never considered playing Del Piero, especially with a tough trip to Perth in the coming week. "He's coming up to 39 and it's round three, it was way too much of a risk," he said. Wanderers coach Tony Popovic said it was comfortably his side's best performance of the season. He said key midfielder Hersi would undergo scans after suffering a foot injury which resulted in him missing the second half. "Derby days are special and you never know how they're going to go in terms of performance and form goes out the window," he said. But this was a very professional, disciplined display. Popovic praised Japanese marquee Ono, calling his goal "special." "In big games last year he always stepped up and was able to provide the magic," he said.
