Barcelona star Neymar is expected to be the headline attraction in Scolari's 23-man party, while Chelsea quartet Ramires, Oscar, Willian and David Luiz could lead the Premier League representation in the Selecao ranks.
Scolari has admitted that he already knows 21 of the players that he will be taking to South America, but did say that he was still considering the final two members ahead of the squad announcement on May 7.
"We have selected 23 players, I still have to determine two players," he told TV Globo.
"We are scouring, watching. This one is younger, that one has more international experience, that other one will feel the pressure a bit more."
Brazil are in Group A alongside Croatia, Mexico and Cameroon for this summer's tournament.
