Brazil's technical director insists there will be no shock inclusions when the group is announced
Felipao has experimented with with his squad since succeeding former coach Mano Menezes in November 2012 but Parreira says the final group will be selected those who have already been “observed and tested.”
“We have worked with more than 70 players and will close the 23 from them, there will be no surprises,” Parreira told Corujao do Esporte.
“Of course we have to pay attention because we still have six months to go and a player could get injured or lose form, so you must have at least three players on your radar for each position, just in case.
“But like [Spain coach Vicente] Del Bosque says, football is a ‘sport of the moment’. We will decide closer to the time, but there will be no surprises.”
Brazil will be looking for their sixth world title, and their first on home soil, when the competition begins in June this year.
The Selecao will meet South Africa in Johannesburg on March 5 in what will be their final friendly match before the squad is announced at the end of May.
