But he is first to admit "it was a game when everything went right, and success is all about consistency".
After making 14 saves, the most by any Premier League goalkeeper in a game since 2006/07, Magpies manager Alan Pardew hailed Krul as "the best keeper in Holland".
Krul aims to impress once again in the games against Japan in Genk on Friday night, and Colombia in Amsterdam on Tuesday.
Dutch coach Louis Van Gaal is reportedly undecided as to who the Dutch number one is, with competition hotting up between Krul, Fulham's Maarten Stekelenburg, Swansea's Michel Vorm and Ajax's Jasper Cillessen.
Tim Krul: "I've got a lot of confidence turning up for the internationals.
"I'm looking forward to meeting up with them. Hopefully I'll get a chance to play.
"I made my debut in Brazil and hopefully, I'll travel and get a chance to play."
