The attacking midfielder, who is currently on loan from Barcelona at Celta Vigo, has been one of the most impressive performers in Spain this season.
Bartomeu recently claimed that talks had taken place between Rafinha and his parent club, but the player himself has said that is not the case.
"I've read about this in an interview, but we've still not spoken yet. Right now I'm focused on my work at Celta Vigo," Inside Spanish Football quotes Rafinha as saying.
"I've not put anything on the table, or spoken with my father about my future. None of this is official."
Rafinha is the brother of Bayern Munich midfielder Thiago.
