Barcelona have an option to sign Fluminense players Gerson and Kenedy, sporting director Ariedo Braida has said.
Catalan newspaper Sport reports that Braida will now travel to Brazil to assess the two players.
"One of our intermediaries lives in Brazil and he has been working on this," Braida told Gazzetta TV. "There has been an option to sign the two for some time now."
Gerson, 18, is an attacking midfielder while Kenedy, 19, is a forward.
ESPN Brasil was informed earlier this month that Barca had already offered €20 million for Gerson and, while Juventus had made a superior offer, the player would prefer a move to the Camp Nou.
Members of the Fluminense hierarchy have informed ESPN Brasil that they are confident Barca will pay closer to €30 million for Gerson.
Barcelona are currently serving a FIFA transfer ban that prevents any new signings from representing the club until January.
