The South Americans last won the competition in 2002, but have failed to survive the quarterfinals in their last two attempts.
Brazil remains the most successful national team in the world, though, and the team is keen to win the World Cup a sixth time at home.
"We are not at all obsessed with the hexa. Neither are we under pressure to achieve it. It's natural to expect a Brazilian triumph, especially when we are playing at home," Alves told Times of India. "Our performances in the Confederations Cup were an eye-opener for everyone. Beating Italy, Uruguay and Spain, three World Cup champions in back to back matches, to lift the trophy is always special. It boosted our confidence tremendously.
"Brazil play every tournament with the sole intention of winning it. We are always confident. We shall be playing at home which should be an added advantage. On the other side, though, the pressure will mount if we play poorly even in one match. The crowd is not going to spare us. However, the experience of the Confederations Cup says that it should go well for us."
The defender admitted that there have been problems organizing the event, but he has little doubt the fans will be right behind Brazil once the World Cup kicks off.
"Yes, there are problems. The majority of our population is not happy with the way things have gone, but they are equally interested in supporting us. And we shall try our best to give them what they want -their cup of joy."
