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.
"I've got a lot of confidence turning up for the internationals," he told the Evening Chronicle.
"I'm looking forward to meeting up with them. Hopefully I'll get a chance to play."
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.
However, the 25-year-old Newcastle stopper is confident he will represent his country in next year's World Cup in Brazil, the country he made his full international debut against in June 2011.
Krul added: "I made my debut in Brazil and hopefully, I'll travel and get a chance to play."
