The former Selecao star, who lifted the trophy himself just under two decades ago, has little faith in the hosts' chances of landing a sixth title
The Selecao were surprisingly beaten in last summer's Olympic final, a result which ultimately cost Mano Menezes his job, and have yet to really click under his successor, Luiz Felipe Scolari, who on Tuesday raised eyebrows by leaving former Ballon d'Or winners Ronaldinho and Kaka out of his squad for this summer's Confederations Cup.
Romario does not feel in a position to judge the merits of Scolari's latest squad selection on account of the time-consuming nature of his political life, but the congressman does not feel that Brazil are currently playing well enough to challenge die Mannschaft for the game's biggest prize.
"Germany will win the World Cup," the former Barcelona striker told O Globo.
"As I assumed the chairmanship of a committee this year, I am missing out on what is happening in football. I have not had the time. So, assessing the latest squad would not be fair. We must always trust in the coaches.
"But if Brazil continues to play they way they are playing, unfortunately, given the growth of rivals, our chances of victory in the Confederations Cup and the World Cup are not very positive."
Brazil have dropped to 19th in Fifa's world rankings, though their fall can be somewhat attributed to the fact that have not had to qualify for the World Cup, meaning less ranking points have been available to them over the past two years.
