The Magpies' No.1 was among six men selected in his position by Netherlands coach Louis van Gaal to face France before being cut but vows to push his case until the season's end
The 25-year-old was one of six goalkeepers named in Louis van Gaal's original party for a friendly with France on Wednesday before being cut in favour of Jasper Cillessen and Jeroen Zoet.
Despite the setback, Krul claims that a ticket to Brazil is not out of the question - provided that he can put in some impressive performances for the Magpies between now and the end of the season.

"I'm going to do my best to show him that I should be on that plane to Brazil.
"He hasn't phoned to explain his decision but I don't think the manager has to do that."
After going four games without a win, Newcastle have picked up maximum points from their last two games courtesy of victories over Aston Villa and Hull City.
"We had a bad month and I think we have to be honest about that," Krul continued.
"We have turned it around with two great wins and the only thing I can do now is impress in the next 10 games."
