isn't the matter of television timing the major obstacle for us ie getting the event to the mass international audience at convenient times?
FIFA (like the Olympics) demand total control and access to any venues for the entirety of the tournament. Using the MCG for a FIFA World Cup in June/July would leave the ground without AFL for at least six weeks.
Footy pays the bills, year in, year out, in Victoria. It's why we didn't even get a quarter final for the current Women's World Cup.
TV may be a bonus as games would be on in prime time in emerging Asian markets, and some games would be on at good times in the USA. Europe would be a problem.
