Connor Metcalfe scored the first goal of the A-League season as 10-man Melbourne City started Patrick Kisnorbo s reign with a 1-0 victory over Brisbane Roar.
Metcalfe combined with Jamie Maclaren before applying the finish seven minutes into the second half at Dolphin Stadium on Tuesday.
The midfielder s fifth A-League goal was enough to seal all three points in Kisnorbo s first game as head coach after he replaced Erick Mombaerts.
Adrian Luna was shown a second yellow card for a foul on Rahmat Akbar with just over 20 minutes to go, but last season s beaten Grand Finalists City held on.
Macauley Gillesphey s header grazed the top of the crossbar and Riku Danzaki went close to a late equaliser, but Brisbane were unable to avoid defeat in their new home.
