If there are groups willing to invest in the A-league, starting fresh is the model. Some key questions and answers though:
Is Western Melbourne a desirable area for a team - Yes
Should a professional team be using ironbark fields as a training base - Yes
Are there other regions of the country that deserve a team (Sunshine coast, Wollongong, Canberra) - Yes
Does there need to be another rectangular stadium in Melbourne - Yes
This might sound strange but I'd be looking at building a new stadium in Albion. There is land right near the station on Ballarat Road, which is about to be redeveloped as part of the airport rail project.
That's a site I would be looking at and its central to the western suburbs.
