The Western Bulldogs stand as a major roadblock to Melbourne Victory hosting the A-League grand final in their own city.

The A-League's highest finishers have the right to host the grand final but fixture confusion on May 17, the date of the decider, has led to an impasse between the two codes.

As Wednesday night's 2-1 win over Brisbane Roar moved Melbourne Victory closer to the Premier's Plate, what was once hypothetical to FFA bosses now looms as a very real problem.

With alternative Melbourne venues deemed unsuitable, it's Etihad Stadium or bust for the showpiece match, and the Bulldogs aren't budging.
