Werder Bremen has been linked with the Corinthians-owned midfielder.
Alberto told Radio Globo: “It’s normal that at this moment of the year many things are said about transfers.
“There is a lot of speculation but the plans I have currently for my career are to stay at Fluminense because I want to win the Brazilian Cup with this group of players.
He added: “The only thing that I’m thinking of at the moment are the two games that we have to play against Figueirense. I am not thinking of a transfer to anywhere.”
