Champions League holders Chelsea have been repeatedly linked with the 25-year-old, who has refused to commit his future to Porto.
Hulk’s agent has been quoted as favouring a move to England, but the player himself is concentrating on Brazil’s London Olympic football campaign.
“There is no deal with Chelsea or any other club,” Hulk told Lancenet.
“I have four years left on my contract with Porto and I am focused on the national team. I have not spoken with anyone.
“As everyone knows, I do not want to get involved in such affairs because that removes your focus. My agent handles such things.”
Meanwhile, 19-year-old winger Lucas spoke about his situation at Sao Paulo, amid reports Inter Milan are keeping tabs on him.
“There is nothing concrete that I know,” he said.
“There is only speculation, but I am happy that a big club like Inter are after me.
“My (25 million euro) price-tag? I am not the one who set that figure, but my club. I am only interested in playing football.”
