Brazilian striker Hulk says he is unsure over his future with Porto, amid reported interest in his signature from Chelsea.
The 25-year-old has scored 11 times in 19 appearances this season following on from his sensation haul last term during an historic quadruple campaign.
Hulk fired 36 goals last term as Porto under stewardship of Andre Villas-Boas, before the latter left Estádio do Dragão for Stamford Bridge.
Since then, Hulk has been consistently linked with a move to Chelsea, and some reports suggest the Blues could launch a January bid for his services.
However, Chelsea would have to pay a hefty €100 million to activate the realise clause written into the contract of Hulk, who has also been linked with Manchester City.
And, says Hulk, he is unable to predict what the future holds, although he would be happy to remain in Portugal.
“We never know what is going to happen tomorrow," he stated.
“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.”
