A former hero at one A-League club thwarted his old side as Melbourne Victory drew 1-1 with Brisbane Roar - but it wasn't Ange Postecoglou.

Roar goalkeeper Michael Theo, a two-time championship winner at Melbourne Victory before joining Brisbane, stole the show at AAMI Park on Saturday night with several important saves.

Victory coach Postecoglou's hopes of securing a win over his former club were scuttled virtually single-handedly by Theo in a superb goalkeeping performance.

Two important stops from Marco Rojas shots in the first half were followed by a world-class save in the 74th minute to deny Gui Finkler - and what would have been a win for the Victory.

The Victory totally controlled the opening 20 minutes, with Rojas running amok and the Roar looking clueless.

But the Victory's wobbly defence - their problem all season - found a new and inventive way to leak a goal against the run of play after 24 minutes.

Fullback Diogo Ferreira's fresh air swing at a ball across goal gave Roar striker Ben Halloran a half-chance, and he punished the Victory with the superb finish they had been unable to find to that point.

The Roar controlled the remainder of the first half and maintained its 1-0 lead to halftime. The home side equalised four minutes after the break.

Midfielder Mark Milligan's thunderous shot from the edge of the 18-yard-box from a Finkler pass levelled the scores and again changed the momentum of the game.

The Victory had the best chance to win it, but after Finkler brilliantly turned a defender in the box, he was denied by Theo's remarkable one-handed save from point-blank range.

Then Theo stood up again to block Archie Thompson's shot just minutes later, and ensure the Roar a share of the points as its defence held firm under a late onslaught.
