Coming into the match, Sydney FC's talismanic front-three were tipped to tear a leaky Brisbane Roar defence to shreads, with the Roar previously winless under interim coach Darren Davies.

But the Sky Blues' misfiring attacking trio wasted several opportunities in the opening 60 minutes, and although they took the lead through Danny De Silva, eventually shipped two late goals to sink to their fifth loss of the season.

"We started very well, we played very good in the first half and defensively we were strong," Corica said.

"The only thing we didn't do, was score more goals.

"In the second half, we turned the ball over a couple of times and they countered us, scoring two goals."

Despite Milos Ninkovic blazing over an open goal and lacklustre performances from Adam le Fondre and starting debutant Reza Ghoochannedjad, Corica refused to single out a poor performance.

"There was no complacency," he said. "We played well, we just didn't finish the job off when we had the opportunity, that's what it comes down to.

"(Ghoochannedjad) played well, but I think he got a little tired. He and Adam (le Fondre) combined well. Milos Ninkovic always plays well for us."

After missing the opportunity to leapfrog Melbourne Victory to within two points of table-topping Perth Glory, Sydney will now be hoping a draw between the two sides keeps them within touching distance.

Perth in particular have a winnable run of matches in front of them, facing the likes of Brisbane, Western Sydney Wanderers and an inconsistent Melbourne City side.

The Sky Blues face Central Coast Mariners before tough matches against Wellington Phoenix and Adelaide United, while Melbourne Victory face Wellington before the Melbourne Derby.

"We got sloppy with the ball," Corica lamented. "The humidity got to them, you switch off for a moment and we've got to fix it next week.

"Definitely three points missed today, we wanted to close the gap on Perth Glory. We'll have to wait and see what happens (between Perth and Melbourne Victory)."
