Defensive lapses proved costly and have left Sydney FC battling to advance from their Asian Champions League group after surrendering the lead three times in a thrilling 3-3 draw with China's Shanghai SIPG.
Substitute Alex Brosque looked to have earned the Sky Blues their first win in three games with an 84th minute tap in at Sydney's Jubilee Oval on Wednesday.
But former Chelsea star Oscar set up Brazilian compatriot and man of the match Elkeson for an 89th-minute equaliser.
Between them, Oscar and fellow Brazilian international and SIPG captain Hulk set up all three of Shanghai's goals.
The result leaves Sydney with two points and bottom of their four-team group with two of their three remaining games away from home.
"I'm disappointed with the point, but pleased with the performance,.' Corica said.
"I think a lot of people didn't expect us to get anything out of this game tonight and I think we proved a lot of people wrong."
Sydney produced one of their most fluent attacking displays of the season, but were punished for defensive lapses.
"A little bit sloppy with the three goals, we didn't defend crosses very well ,we planned to get more numbers out in wide areas to stop those balls coming in," Corica said.
An action-packed first half produced four goals with marquee Siem de Jong putting the Sky Blues ahead in the third minute, when his shot deflected off a visiting player.
Oscar gave the home side a warning when he was put through, but his lob over Sydney goalkeeper Andrew Redmayne also cleared the crossbar.
The playmaker then turned provider in the 27th minute when his left-wing cross was headed in by Lu Wenjun.
Sydney regained the lead when English striker Adam Le Fondre blasted a penalty into the roof of the net after a handball call against He Guan.
The lead lasted just five minutes when Hulk's right wing cross was headed home by Yu Hai .
SIPG created the chances early in the second half but Sydney had most of the opportunities in the final third of the game, despite losing left-back Michael Zullo, who is expected to miss Saturday's Sydney A-League derby, to injury.
Iranian Reza Ghoochannejhad had two attempts saved and was wide with another and substitute Milos Ninkovic put another shot over the bar.
SIPG coach Vitor Pereira also rued some sloppy defending and said he had problems replacing important players in defence after halftime.
"The first half we created situations to score four or five goals but two mistakes and we conceded two goals," Pereira said.
"The second half we faced new problems and we have to fight for the result with character and spirit."
