Italian agent Sabatino Durante says Juventus have a deal in place for Sao Paulo starlet Lucas Piazon.
Brazilian reports say Chelsea have opened talks with Sao Paulo for the teen.
But Durante told Tuttosport: "Juventus have already closed [a deal for Piazon].
"The problem is that the boy can't come to Italy until he is 18.
"Lucas will be 17 in a few days' time, but his family has venetian orgins: if an Italian passport arrives, he could arrive in Turin in June.
"In any case, he is a fantastic player, a chosen one.
"He is one of those talents who are born every 50 years.
"He is a second striker who could play for any team in Europe. He is a really strong player."
