Brazil international Bernard has admitted that he is flattered by Porto's interest, but has stressed that he does not have a preference as to his next destination.
The Atletico Mineiro midfielder is continually being linked with a move to Europe, with clubs such as Borussia Dortmund, Tottenham Hotspur and the Portuguese champions all closely monitoring his situation, and a move to the Dragao could prove to be too tempting to turn down.
"I do not really have a preference. The European transfer window is open at the moment and I have also been linked with other good clubs," he told A Bola.
"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.
"When I heard about Porto's interest, the first name that came to mind was Hulk. I have spoken with him and he's told me all about Porto.
"He's assured me that Porto are a big club who are run very well. He said nothing but wonderful things."
The 20-year-old has a contract with Atletico Mineiro until 2017.
