Besides the issues with building stadiums in states without a football tradition, Brazil is facing the problem that people just don't go to the stadium much. For example, the national league, which finished its third round last week, has had only 3 games with more than 20000 spectators so far.

That was already a big problem before the World Cup, and only became bigger after it since the cost of maintaining the stadiums is much higher now, and so are ticket prices.

That's quite low - only the bottom two Premiership teams averaged less than that for 2014-15. But presumably it'll pick up over the season?
