Newcastle made an attempt for Elanga over the summer.
He told Fotbollskanalen, "I have heard the same as you have, there will always be rumours in football, but I have a contract with Nottingham and we had a game the day before so I couldn't focus so much on it (what was written about Newcastle).
"The environment in Nottingham is good. It is clear that you can see that Newcastle are interested, it means that I am playing good football when a big club shows interest. But Nottingham is also a big club, they have won two Champions Leagues, even though it was before I was born. But I am happy in Nottingham and have a contract there."
Elanga says Isak spoke to him about the rumours.
"Isak talked to me about it. But I said the same to him as I say to you," added Elanga.
