Plague most of these issues are down to the Brazilians and the politics of the country.
FIFA asked for 8 stadiums
Brazil insisted on 12 stadiums
4 of them were built in cities where the local club isn't even in the top flight or close to being a top flight club
Manaus Natal BrasÃ*lia and Cuiaba are white elephants from day 1
Most were built for the benefit of political relationships for people based there.
Areas with legit clubs with serious passion for the game were overlooked.
Be the equivalent of Australia building stadiums in the Gypo Coast Darwin Alice Springs and Canberra yet overlooking Adelaide Perth Newy etch who would have uses for stadiums
Even in Porto Alegre where Australia played Holland the stadium was rebuilt for the local club who plays there at 51k yet Gremio had a new stadium built 2-3kms away in 2012

Which would have more than done the job but politics got in the way
