Skysports.com reports how the Dutch stopper has emerged as one of the brightest young goalkeepers in the Barclays Premier League, attracting interest from a number of potential suitors.
The 23-year-old turned in a heroic display at Old Trafford in November to earn Newcastle a 1-1 draw against the Red Devils, and Sir Alex Ferguson is believed to have been bowled over by his performance.
However, despite speculation linking him with a January move to Manchester United, Krul insists he is fully committed to St James' Park, and says he wants to repay the faith shown by Magpies boss Alan Pardew.
"The manager has always insisted that if you're good enough, then it doesn't matter how old you are," he said. "I've always firmly believed in that myself, and I'm just glad I've got my chance.
"Maybe in the past, 'keepers have traditionally been a lot older, but there are some top young goalkeepers around now and that's very important.
"I want to stay at this club for a long, long time and, hopefully, because I am still only 23, I can do that."
Krul retains aspirations that his form for Newcastle will help confirm his place in the Holland squad for this summer's European Championships, and says that the experience he is gaining in the Barclays Premier League will stand him in good stead for the future.
"I am loving life, and going to places like Old Trafford is special," Krul added. "Every game is bringing new challenges for me and it's up to me to keep rising to those challenges.
"I'm very pleased with my game at the moment and with the way things are going. To be honest, I couldn't have wished for better. We are answering a lot of questions as a team this season and everyone is playing their part.
"To be in the squad for Euro 2012 would be the icing on the cake after what will hopefully be a successful season with Newcastle."
