Barcelona have opted not to sign Gerson, meaning the Fluminense star will now join Roma instead.
According to Ben Gladwell of ESPN FC, Fluminense's president, Peter Siemsen, told Sofia Miranda and Matheus Frigols of Globoesporte:
We've received a formal offer from Roma, which is very good, and we have decided it was right to accept it. Gerson and his father have given the all clear. We've told Barca, who have not taken the option they had on him.
Football journalist Fabrizio Romano expanded on the report:
Gerson (1997, Brasil) will go to AS #Roma starting by next january.
