The Melbourne Victory handed Brisbane their biggest A-League defeat and extended their winless streak to nine with a 5-0 thumping at Suncorp Stadium on Tuesday.
Kevin Muscat's men lived up to their billing of favourites, but were helped by some Roar wastefulness before running away from a re-jigged Brisbane in the second half.
Melbourne City improvised their way to another A-League win, beating battlers Brisbane Roar 1-0.
In the absence of sidelined striker Bruno Fornaroli, marquee full-back Ritchie de Laet led the line for City at AAMI Park, scoring the only goal of the game.
De Laet got in front of marker Jack Hingert and swept in Rostyn Griffiths' cross on 52 minutes to give Warren Joyce's side their third straight win in 2019.
The triumph lifts City to 23 points, equal with Melbourne Victory and Sydney FC.
