Porto forward Hulk has said that he will not rule out a potential exit from the Estadio do Dragao this winter.

The Brazilian striker, who starred under current Chelsea boss Andre Villas-Boas during his time with the club, has been linked with a switch to Stamford Bridge throughout the season in a move that would reunite him with his former manager.

Meanwhile, the 25-year-old has said that he does not believe there should be any problems over a potential transfer.

"We never know what is going to happen tomorrow," he told Record.

"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."

Hulk, who arrived in Portugal in 2008, scored 36 goals in 53 games last season.
