The Newcastle United goalkeeper has five international caps to his name, but has not featured for his country since February's friendly draw with Italy.
Michel Vorm, Kenneth Vermeer and the injured Maarten Stekelenburg are all fighting it out to be Van Gaal's first-choice keeper ahead of Brazil 2014, which Netherlands have already qualified for.
"I look forward to show my skills again it’s been a long time since that the coach has seen me at work," he said.
"The World Cup is at the end of the season so we still have a long way to go in which I can prove myself. Things can change.
"The coach has no fixed team yet, it's all still open. These two qualifying matches are ideal moments (to prove yourself).
"Italy (at) home was my last match. Then I suffered injuries, but fortunately I am now fit again."
