The highly-rated 22-year-old has been linked with a move to Chelsea and has been touted as a long-term replacement for John Terry, whose contract ends at the end of the current season.
However, the Magpies defender says he's not interested in the rumours.
"I saw a little bit [of the speculation]. I really don’t know where that has come from. I can’t pay any interest in it.
"I am a Newcastle United player and my job is to stay here and hopefully be picking up a trophy at the end of the season.
"That is a long way away and that is my main objective and I won’t be thinking about anything else".
