Two late goals has seen Adelaide United secure the three points at Suncorp Stadium on Friday night.
The Roar started positively and took an early lead as Italian marquee Massimo Maccarone snuck a volley past Paul Izzo for his first goal in orange.
The goalscorer gave the Brisbane faithful reason for optimism, creating chances throughout the contest and proving a major headache for the Adelaide defence.
Brisbane controlled the majority of the contest and had chances early in the second half that would have put the Roar two goals to the good.
Head Coach John Aloisi was disappointed to not take all three points after his side carved a number of quality opportunities in the opening period.
"We're disappointed that we didn't put the game away, even in the first half. We had some good chances and they didn't have many opportunities," Aloisi said.
"We started the second half with a clear opportunity to score but then they got on top of us and that was mainly because we gave away the ball too often."
Adelaide finished with a flurry, firstly equalising through substitute Ryan Kitto before Johan Absaolonsen netted the go-ahead goal for the Reds in second-half stoppage time.
For the second time this season, Brisbane fielded three teenagers as Rahmat Akbari joined Nick D'Agostino and Joe Caletti on the pitch in the second half.
Brett Holman also played his first minutes of the Hyundai A-League season in the second-half and immediately looked threatening, firing dangerously at goal with a tick over 20 minutes to play.
The Roar return to Suncorp Stadium next Sunday, 22 October to face Newcastle Jets (4pm KO) and Aloisi says he expects his players to be ready and raring for that contest.
"It's disappointing to have two losses in a row, but we can either roll over and feel sorry for ourselves or we can fight and make sure we're ready for the next game. I know what I'm going to do and I expect my players to do that as well," Aloisi said.
Story of the game
Brisbane dominated the early stages of the game, creating a number of set-piece opportunities, and more importantly, taking an early lead with Massimo Maccarone's first Brisbane Roar goal.
The Roar threatened regularly from the right wing in the first half with Petros Skapetis, Massimo Maccarone and Nick D'Agostino combining well.
Brisbane had their moments in the second half with Paul Izzo called upon for back-to-back saves from point-blank range against D'Agostino and again in the 70th minute when substitute Brett Holman struck a swerving shot.
The Roar defended strongly and had good control for large portions of the match but the Reds converted two opportunities late on to take the three points.
Brisbane Roar – Maccarone 8’; 0-1
The Roar take an early lead through marquee striker Massimo Maccarone, who connects with Corey Brown’s brilliant pin-point cross at the far post, squeezing a volley past Paul Izzo.
Adelaide United – Kitto 88’; 1-1
Baba Diawara’s simple pass to Ryan Kitto provides the foundations for the substitute to net the equaliser, as he cuts inside and fires home at the near post.
Adelaide United – Absalonsen 90+2’; 1-2
A vicious strike from Johan Absalonsen on the turn cannons off the underside of the crossbar, putting the Reds in the lead at the death.
