Melbourne Victory on cusp of Premiers’ Plate via controversial win over Brisbane Roar at Suncorp

Dimitri Petratos of the Roar breaks away from the defence of Carl Valeri of the Victory

Melbourne Victory have all but sealed the A-League Premier's Plate with a 1-0 win over Brisbane Roar at Lang Park on Saturday evening

Mark Milligan's controversial first-half penalty was enough to keep Victory on top of the ladder with a three-point buffer and just one round remaining.

The only way Kevin Muscat's side can lose from here is if Central Coast Mariners spring a huge upset next Sunday and Sydney FC defeat Wellington by a margin wide enough to erase the Victory's edge in goal difference.

Victory's task in Brisbane was seemingly made easier when the Roar - with a nod to Tuesday night's AFC Champions League tie against Beijing Guoan in China - unveiled an almost unrecognisable line-up peppered with youth team players.

Thomas Broich, Matt McKay, Luke Brattan, James Donachie and Devante Clut were not considered for selection, while Corey Brown (back), Andrija Kaludjerovic (ankle), Jack Hingert (flu) and Brandon Borrello (knee) were also ruled out.

Defenders Luke DeVere (quad) and Shane Stefanutto (calf) have succumbed to likely season-ending injuries, and there is no end in sight for goalkeeper Michael Theo's battle with a groin complaint.

In their stead, coach Frans Thijssen handed starts to Shannon Brady, Patrick Theodore, Lachlan Jackson and George Lambadaridis, with 18-year-old debutants Abrahim Yango and Luke Pavlou named on the bench.

But their inexperience did not make the night any more straightforward for the visitors.

Brisbane hit the woodwork twice in the opening half and did a gallant job of holding Victory at bay - until referee Ben Williams awarded a controversial penalty just moments before the interval.

Acting on the advice of linesman Matthew Cream, Williams blew when Carl Valeri appeared to have been brought down by Lambadaridis while shooting from the edge of the six-yard box.

Replays, however, showed no firm evidence of contact from Lambadaridis, revealing Valeri fell over after kicking the turf - much to the disgust of the 11,582-strong crowd.

Milligan expertly converted the spot kick, but the Victory could have taken the lead much earlier had Fahid Ben Khalfallah showed the same poise with any of his three excellent first-half chances.
