The 21-year-old has been linked with Manchester United, Chelsea and Manchester City.
“I have my mind only focused on Benfica,” he told A Bola.
“I am surprised about what is being said, so the only thing that I can say when I read the news is that I only have my mind on Benfica and the interests of the team.
“I don’t want to think about a transfer because as there hasn’t been any official proposal I can’t talk about being transferred.
“And that is why I repeat all the time that for the moment I only keep my mind on Benfica.”
