Holders France are also among the contenders, while England, Spain and Germany will be expected to provide stern competition at world football's showpiece event.
Roberto Carlos was in the team that won Brazil's fifth and most recent World Cup in 2002, and he believes Tite's side will end a 20-year wait to be crowned champions in December.
"The most important thing is that Brazil have a great team," he told reporters. "It's time to win because the last photo we have is ours [in 2002].
"I am very optimistic. It is not easy to win a World Cup. In recent times, the Brazilian team are as usual, since our time, they have played great games, but have never been so good.
"The Copa America is important but for the Brazilians, this World Cup is going to be very important and has a special flavor, the moment of the national team is very good.
"At least the European press put Brazil as one of the favorites. This is already an important factor.
"Luis Enrique commented on it the other day, if you ask any other national team coach, the Brazilian team is one of the four favorites for this World Cup. If they prepare well, Brazil will win again."
Brazil start their World Cup campaign against Serbia on November 24, with clashes against Switzerland and Cameroon to follow in Group G.
