Porto striker Hulk insists he is yet to agree a move to Chelsea.
Chelsea are widely seen as favourites to sign the Brazil international during the summer transfer window, but it is thought they are unwilling to meet Porto's valuation.
Hulk, who will be part of the Brazil squad at the upcoming London Olympics, has a €100million buy-out clause in his contract at the Estadio do Dragao and it is thought Porto are unwilling to let him leave the club for less than €40m.
Agent Teodoro Fonseca has already confirmed interest from Chelsea and Paris Saint-Germain, while Tottenham are also believed to be showing interest in the 25-year-old following last week's appointment of former Chelsea and Porto boss Andre Villas-Boas as their new manager.
But Hulk insists his immediate focus is the Olympic Games.
"There is no deal with Chelsea or any other club," he 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."
Fonseca had last week stated his client was ready to quit Porto and seek a move to England to help boost his chances of playing for Brazil at the 2014 World Cup.
"Hulk is among the most coveted players in Europe," he said.
"He feels good at Porto, he is part of the family, but a departure is not impossible.
"He wants to play at the 2014 World Cup in his homeland and playing in England makes this more realistic."
