Barcelona have completed the signing of Sao Paulo attacker Gustavo Maia.

Globoesporte says the 19 year-old will join Barca B next season after Sao Paulo accepted a €4.5m offer. Barca had already paid €1m last year for first refusal on Maia.

Sao Paulo maintains 30% of the player's economic rights.

Barca will count on Maia as a B team player, with Barca B currently in the middle of promotion playoffs in Segunda B.
