FIFA President Sepp Blatter says Brazil might have been the wrong choice as host of the 2014 World Cup if the tournament is affected by more social protests similar to those at the Confederations Cup.
Blatter told German press agency DPA that "if this happens again, we have to question whether we made the wrong decision awarding the hosting rights."
Hundreds of thousands of Brazilians took to the streets during the warm-up tournament in June, demanding better public services and expressing their anger over the cost to stage the World Cup.
After the Confederations Cup, FIFA spoke with the Brazilian government. Blatter says it's "now aware that next year the World Cup shouldn't be disturbed," adding that he'll discuss the matter with Brazil President Dilma Rousseff in September.
