After beating Spain 3-0 in the Confederations Cup played earlier this year, Ronaldo sees no reason why they can’t do it again.
"It's not the same as the World Cup, but the team showed their potential at the Confederations Cup," Ronaldo told the official Fifa website.
"With time to train, Brazil improved a great deal. It really gave Brazilians hope that we might win the World Cup at home. We’ve got a great chance.
"Spain and Germany are candidates, but Brazil have shown how strong they are, and we’ll be playing at home. I’d say that the favourites are Brazil, Germany and Spain, in that order."
