BEWARE a Brisbane Roar scorned.
The A-League champion left that message of warning after producing a stunning 7-1 demolition of Adelaide United at Suncorp Stadium.
BRISBANE ROAR 7 (Henrique '21, '36, Besart Berisha '23, '26, '29, '69, Issey Nakajima-Farran '81)
ADELAIDE UNITED 1 (Dario Vidosic '5)
The Roar was at its swash-buckling best against the hapless United - Besart Berisha grabbing a four-goal haul, Henrique a double and Issey Nakajima Farran adding a late strike.
And that was despite Brisbane conceding its first goal of the season in the fifth minute - former Roar player Dario Vidosic scoring against his old club.
"Obviously we haven't conceded yet and people were sort of saying that was the best way to hurt us," Roar coach Ange Postecoglou said.
"(But) this group of players just does not have an off day and doesn't want to.
"Tonight was the complete performance, we didn't beat just anybody … but they just met us on a good night."
Adelaide shocked the home crowd into silence when Vidosic evaded the offside trap to take the mantle as the first player of the season to score against the Roar.
Vidosic - son of Roar assistant coach Rado Vidosic - took advantage of a receding defence to create a half metre of space and shoot past the outstretched Michael Theoklitos.
But the visitors may have thought twice about scoring against the Roar if they knew what was heading their way in the next 15 minutes.
A goal down for the first time in 275 minutes, Brisbane returned fire by unleashing a devastating first-half five-goal barrage.
Winger Henrique started the avalanche - scoring from the penalty spot after Mitch Nichols was felled in the area by Adelaide captain Jon McKain - before Berisha grabbed the spotlight with one of the fastest hat-tricks in A-League history.
The Albanian notched his first in the 23rd minute, finishing off a beautiful length-of-the-field move, before slotting his second just three minutes later.
And the lightning hat-trick was completed when the goal-poacher was in the right place at the right time to covert Broich's pin-point cross.
"It's so easy to score goals because the team is working so hard for me," Berisha said.
"I really have so much fun here with Brisbane."
The first-half rout was complete when Henrique dusted himself off after being brought down in the area to score his second penalty of the night.
Both coaches headed to their benches early in the second half, but the Roar maintained control and seemed happy with its four goal advantage.
Until Berisha added number four to his tally.
Feeding off a slick ball from the introduced Farran, Berisha showed strength and precision to hold off McKain and beat Eugene Galekovic one last time.
Postecoglou withdrew Berisha to rapturous applause, but even with their leading man off the field, the Roar still managed to find the back of the net - Farran finishing off a quick move to score his first A-League goal and round off a 7-l victory.
