The Brazil international is highly sought after and has been linked with a move to the Premier League with Tottenham believed to be interested in his services.
But Porto appear best placed to secure a deal for the 20-year-old as the player himself has spoken out about the possibility of a transfer to Portugal.
"When they talked about Porto, the first name that came to mind was Hulk, who succeeded there," Bernard told A Bola.
"I talked with him so that he could tell me everything about the club. He told me to that it is a big and very well run club. He said wonderful things about them."
While Bernard praised Porto, he stopped short of saying he had a preference for the Portuguese giants.
He added: "It's difficult to say I have a preference for Porto - because of the language, customs or club history - as the European transfer window is open at the moment and the other clubs I have been linked with are good too.
"I prefer to say that I have no preference. But Porto are a very good club, with a great structure and are always in the Champions League. I am proud to be linked to a club like that."
