The powerful forward does not shut the door on a big-money move in the summer, but insists that he remains as happy as ever at the Estadio do DragaoHulk has cast further doubt about his long-term future at Porto, saying that he could leave the club in the summer.
The Brazil international has been strongly linked with a new challenge at the end of the season, with Chelsea and Paris Saint-Germain both credited with an interest in the 25-year-old.
Hulk claims that he remains happy with life at the Estadio do Dragao, but does not rule out a big-money transfer in the summer.
"No one has contacted me, also because I do not get involved in such situations," he wrote on his Twitter page.
"I have an agent and he handles such things for me. If something must happen, he will find what is best for me.
"Thanks to God, I am fine in Portugal and I am still motivated. Every year, a lot is speculated about my exit.
"I am in my fourth year at Porto, I am focused on this club and I have four years left on my contract.
"If I have to leave, it will certainly be a good move. If I have to leave for one of the big leagues, I would do it happily."
The former Tokyo Verdy forward, who moved to Porto in 2008, has a €100 million release clause attached to his contract, which runs out in 2016.
He has scored 16 Portuguese Liga goals this season, helping Porto retain their league crown.
