Rivaldinho, the son of former Brazil international Rivaldo, has joined Dinamo Bucharest.
The 21-year-old has moved to Romania after being released by Internacional in his homeland.
Rivaldinho began his career at Mogi Mirim in the Brazilian second tier, making 47 appearances, including on one notable occasion with his father in 2015 when they both scored.
He then moved to Portuguese club Boavista, making three appearances before returning to Brazil in a bid to kickstart his career.
Rivaldo scored 86 goals in five seasons at Barcelona, and also enjoyed spells with Deportivo La Coruna, AC Milan and Olympiacos.
Eighteen-time Romanian champions Dinamo Bucharest are currently in fifth place, 13 points behind leaders FC Viitorul.
