Five-star Brisbane crushes Victory

But it put its best foot forward with a record 5-0 second-round win over Postecoglou's Melbourne Victory at Suncorp Stadium on Saturday night.

There was no love lost ahead of the long-awaited clash between Postecoglou and the team that he guided to back-to-back A-League championships.

Especially after he'd taken exception to Roar's very public desire to send home its former mentor a loser.

And Brisbane danger man Thomas Broich's claim that former assistant and now Roar coach Rado Vidosic was the "brains" of its past championships rather than Postecoglou didn't go down well either.

However, even Postecoglou could not have argued with the result as Victory suffered a 5-0 loss for the first time in the glamour club's history as Roar looked to make a point in front of 17,364 fans.

Brisbane brought the crowd to its feet when it opened the scoring after German maestro Broich capitalised on a clever Massimo Murdocca throw-in in the 22nd minute to find the back of the net.

And within a minute big Erik Paartalu made it 2-0 when his header connected with a Broich corner.

Victory was on the back foot in the second half when Besart Berisha finished off an end-of-the-field effort sparked by a clever clearing kick by Roar keeper Michael Theo in the 64th minute.

Mitch Nichols scored Brisbane's fourth when he fed off some good work from Ivan Franjic and Roar sealed the record win over Victory when Albanian international Berisha found the back of the net in stoppage time.

Victory was always going to be vulnerable without the likes of key players Archie Thompson, Mark Milligan (Socceroos) and Marco Rojas (All Whites) due to international duty.

Especially after its 2-1 last round loss to arch rival Melbourne Heart.

But it seems nothing prepared Postecoglou's side for the onslaught ahead at Suncorp Stadium.
