Porto striker Hulk, who has been linked with a move to Chelsea, has refused rule out a move away from the club this month, saying he doesn't know what will happen during the transfer window.
The Brazil international has been on Chelsea's radar since Andre Villas-Boas left Porto to take charge at Stamford Bridge last summer and a deal was thought to be close shortly before the summer transfer window closed at the end of August, only for the 25-year-old's huge buyout clause - set at £84million - proving to be a stumbling block.
But Villas-Boas is still keen on being reunited with the forward, and his agent last month hinted that a move could happen, providing a transfer fee is agreed.
And now Hulk himself has refused to deny speculation that he could leave the Estadio do Dragao this month, telling Record: "We never know what is going to happen tomorrow.
"I have four-and-a-half years left on my Porto contract but, as I have always said, if some day something good for me and for the club appears, I think there will not be any problem and a deal will be reached.
"As long as it is amicable and good for everyone, I believe it will be concluded without any problem. If I do not leave, then that is fine."
Paris Saint-Germain are also thought to be keen on the forward, who continued: "With all due respect, it is clear that it is different to play at PSG or Real Madrid.
"It is clear that the way those two clubs are looked at is different but what I like is to play football and the only thing I want is to be good enough to do it."
"If the day comes, I will go to where I think I will be happiest."
But if a move fails to happen, Hulk insists he is happy in Portugal, adding: "I am fine here, I am happy here, my family likes living here. I like the city of Oporto and I really like Porto."
