The 62-year-old is to step down from his post with Oranje following the finals in Brazil, and he admits he will be happy to bring his time with the national side to an end.
"I'm sick and tired of being the coach after two years," he was quoted as saying by AD Sportwereld. "I'll miss the eight times I can work with players, but I'll have more time for others."
Van Gaal revealed earlier this month that he rejected the chance to take charge of Tottenham following the sacking of Andre Villas-Boas, and the former Bayern Munich boss claims only the most tempting of offers could convince him not to retire this year.
"Am I in contact with Tottenham Hotspur? Not currently. Basically, I will retire, unless a very great challenge comes along," he said.
Van Gaal went on to state he has already selected a list of 10 players who he will take to the World Cup finals, but hinted that Galatasaray's Wesley Sneijder has yet to convince him he deserves a place in the squad.
"If they are fit, yes," he said of the 10 unnamed players he has chosen. "So 13 spots are open. Is Sneijder fit? He has another three months..."
