Kristian Opseth got Adelaide United's A-League Finals hopes back on track by securing a 1-0 victory over Brisbane Roar on their return to action.

Adelaide were on a four-game losing streak in which they conceded 15 goals when the season was suspended amid the coronavirus pandemic, but club legend Carl Veart got them back to winning ways in his first game at the helm after Gertjan Verbeek's departure.

Opseth headed Ryan Strain's right-wing cross past Jamie Young to put the Reds in front inside six minutes at Cbus Super Stadium.

After Adelaide goalkeeper Paul Izzo tipped Jay O'Shea's free-kick onto the crossbar with a stunning save, Nikola Mileusnic struck the post at the other end on the stroke of half-time.

Substitute George Blackwood hit the bar with a header from Riley McGree's corner 12 minutes from time and Izzo finished the game with eight saves as Brisbane were consigned to defeat in their first game since Robbie Fowler's exit.
