The 25-year-old goalkeeper has become first-choice stopper for Netherlands during his time in the Magpies first team, in which he has been a key figure since establishing himself in 2011.
His performances have impressed several of European football's elite clubs, but Krul has insisted that any rumours of his potential exit are untrue, and that he is focused on his "really happy" life on Tyneside.
"What the papers write I don't take notice any more, I have got a four years contract at Newcastle, I'm really happy," he told Sky Sports News.
"It is my second home, I have been here eight years now, it's a second home and second family. Playing in front of 52,000 Geordies is a fantastic feeling and I don't think many clubs can beat that.
"I love playing for this club, so I just focus on myself and getting a good season this season and then hopefully going to the World Cup."
Krul joined Newcastle's youth academy from native club Den Haag as a 17-year-old.
