As holders, Spain will enter as one of the favourites to triumph, but no European team has ever won the World Cup on South American soil.
Torres, 30, has claimed that could end this summer, but the striker also believes that Brazil will be tough opposition.
"For me, we are still the favourites to win the World Cup, but in a big tournament the hosts are normally favourites as well," he told reporters.
"But not favourites. We're not fools. We know that in Europe there are only two or three great teams but at the World Cup there are plenty who can win without a problem.
"Maybe this time we'll see an African team at least get close to the final."
