Brazil coach Carlos Alberto Parreira has picked out Argentina as the biggest threat to his side's hopes of winning the World Cup.
Holders Brazil are strong favourites to retain their crown, with England and Germany their most likely challengers according to the bookmakers.
However, Parreira told the Jornal do Brasil: "Argentina are very similar to us. If we weighed up both teams we would be very level.
"Our advantage is that we have a stronger attacking line with Ronaldinho Gaucho, Ronaldo, Adriano and Kaka."
The coach also revealed he has not finalised the make-up of his 23-man squad for the finals yet.
Parreira added: "The list began to be formed when I coached the team for the first time three years ago.
"But I have some doubts yet as there are some physical and medical problems, so the list doesn't depend only on me. It's not only a coaching decision."
