Sydney FC exposed as A-League title pretender as Brisbane Roar romps to 5-2 win Sydney's Alessandro Del Piero looks disappointed after a Brisbane goal. IF there's to be a challenge to Brisbane Roar's title aspirations, it won't come from the Sky Blue half of Sydney. Defeated 5-2 by the Roar at Allianz Stadium last night, Sydney FC's deficiencies were all too clear amid a deluge that came from the skies and from Brisbane's sweeping football. To compound the misery, three of the visitors' goals came from Dimitri Petratos, the 21-year-old who went through Sydney's youth system but left under a cloud a year ago. "We were taught a footballing lesson tonight, there's no hiding from that," Sydney coach Frank Farina said. They were more mobile, they moved the ball better and we couldn't live with it. It was unfortunate that Ale (Del Piero) had to go off but that's life. Tonight was a clear indicator of the areas we have to improve in, and sometimes in adversity you learn a lot more than when things go your way. With Brisbane 3-1 ahead by the break, it seemed an age since Sydney had briefly taken the lead. It's provenance was no surprise, Del Piero winning a free kick just outside the box after being lectured by the referee for a very dubious tumble. The Italian picked himself up to curl the set-piece into Michael Theo's top corner, but Sydney fans' delight was tempered by the knowledge of how much the goal was against the run of play - and three minutes later Brisbane duly equalised. Sydney FC's Alessandro Del Piero celebrates scoring a goal from a free kick. As Sydney tried to clear their lines from a corner, Luke Brattan's astute pass found Thomas Broich all alone in front of the Sydney goal. Broich calmly found the bottom corner, and a minute later Sydney's night began to implode. Henrique ran at Seb Ryall, skipped past him and seemed to be fouled by the defender's hand. The penalty was given, and converted twice by Petratos after he was ordered to retake his first effort. Brisbane's Dimitri Petratos scores his third goal against old club Sydney FC. Ten minutes before halftime Brisbane constructed a mesmeric piece of football. It was pass and move football in its purest form, a series of short passes as Brattan, Petratos, Broich, McKay, and Broich again all combined before Petratos finished the move with a rasping, rising drive. At 3-1 the game seemed secure, ­especially when Del Piero failed to emerge for the second half, and Brisbane cruised. Brisbane's Dimitri Petratos celebrates scoring his second goal against Sydney FC. But they turned up the heat again, and Broich timed his run superbly on 77 minutes to spring Sydney's offside trap. As he brought the ball down, Nikola Petkovic barged him to the floor. Petratos smashed his penalty into the top corner once more to complete his hat-trick, and then Ivan Franjic was allowed to stroll through Sydney's defence and fire home the fifth in the dying seconds of the game. Richard Garcia stabbed home a corner right on fulltime but it was ­little consolation for the Sky Blues. Full replay of Sydney FC's clash with Brisbane Roar at Allianz Stadium.
