The in-demand forward has reiterated his desire to move on to new pastures this summer in a bid to be part of Mano Menezes' squad for the 2014 World Cup in Brazil.
Despite winning back-to-back Portuguese Primeira Liga titles, the 25-year-old is keen to take on a new challenge on a more prominent stage, claiming it will increase his chances of representing Brazil in forthcoming tournaments.
Hulk's agent recently confirmed Chelsea and Paris Saint-Germain are not the only clubs to be interested in his signature, a scenario the former Sao Paolo youth product has now also alluded to.
"I honestly do not know what my future holds, but I am not crazy to leave Porto," Hulk was quoted by Globoesporte as saying. "All I know is that there are several other clubs besides Chelsea and Paris Saint-Germain who have expressed an interest in me.
"If negotiations reach a good stage and some European club comes to an agreement with Porto, then I will leave. I know there are two years left [to the 2014 World Cup in Brazil], but in a way there is not much time left. All I can promise is to give my all for my club to earn a place in the squad."
However, Porto has denied receiving any offers as yet for the player, who has amassed nearly 100 appearances for the former Europa League winner.
