The teenage fullback has joined from Sport Recife and Cunha spoke with the youngster as Wolves competed with Chelsea for his signature.
He told the club's website: “It's funny because my mum supports Sport Recife, the club that he comes from, and I told her that I’d talked with him to come here and she asked me to get her one of his Sport shirts because she was such a fan of his.
“It’s funny and I’ve talked with him about this, but these kinds of things are very beautiful in life.
"He’s come here, he’s got a very beautiful history, very similar to my one, and to play together here I hope will open the way (for more people to from his region) to come to the Premier League and to a new country, so I’m very happy to be this guy.”
