Hulk is adamant that he has held no discussions with any potential suitors.
Hulk told Lancenet: "I have four more years on my contract with Porto, and I'm focusing on the national team (ahead of the 2012 Olympics).
"I haven't talked to anyone. As everyone knows, I don't follow negotiations closely as that will make me lose my focus. I let my agent deal with that stuff."
Porto are also adamant that they have received no official approach for the 25-year-old striker.
"What is certain and can't be denied is that so far there have been no offers for Hulk," president Pinto da Costa told RTP.
"There have been talks regarding other players, but not those mentioned in the papers."
