Brazil international Hulk, who is reported to be a top transfer target for Chelsea, has hinted that he could be on the move this summer.
Speculation suggests UEFA Champions League winners Chelsea are ready to spend big in an effort to lure the Samba star away from Porto.
A £38million bid is said to be in the pipeline, with Roman Abramovich prepared to bankroll another lavish spending spree.
Hulk has been heavily linked with a switch to Stamford Bridge in the past, only for no deal to materialise.
He is, however, prepared to admit that the time may have come for him to leave Portuguese football and try his luck elsewhere.
Asked what the future held for him, Hulk told Lancenet: "I will always continue to work hard and keep my feet on the ground, regardless of whether I stay at Porto.
"I have won many titles in the past four years at Porto, and I think that I have a great relationship with everyone.
"If the time has come to move on, I'll do so with a good feeling. I have enjoyed a great time here.
"I'm sure that they will understand the motives behind my decision if I leave."
Hulk, who is contracted to Porto until 2016, added: "The club and its fans will forever have a place in my heart.
"I can only thank them for all the affection they've shown me."
