The Den Haag strikers, who found it difficult to get past the Newcastle defence, rarely bothered him but the 26-year-old dealt comfortably with the few things that came his way.
Krul said: "It was another good game for us. We didn't concede any goals and that is great for the defence and me and I thought we played pretty well.
"It was nice to be back and see some old friends. I have great memories of being with Den Haag who helped me to get a move to England and Newcastle.
"I had eight years at the club and I will always be grateful for what they did for me. There was a lot of the Krul family at the game.
"It would have been better to win the game and we had enough chance to score, but right now getting everyone fit is the main thing."
