The Netherlands boss is angry that Brazil play their final Group A fixture against Cameroon after Holland’s earlier Group B kick-off against Chile on Monday afternoon, despite having played each of their previous fixtures before the Dutch.
On top of having cooler conditions to play in with a later kick-off, Brazil will also have an advantage of knowing who their potential opponents will be in the Last 16 before the start of their match against the Indomitable Lions.
Van Gaal has labelled FIFA’s fixture scheduling as “trickery” which favours the host nation.
"For every match FIFA have this advertisement around fair play," said Van Gaal.
"FIFA plays these tricks and it's not a good thing. It's not fair play.
"We're going to focus on a victory against Chile and I don't think that will be affected by the fact Brazil will play after us.
"I am just assuming they [Brazil] will do their sporting duty. Why on earth are they [FIFA] doing that [with the fixture schedule]? That is the question."
With the winners of Group A facing the runners up of Group B (and vice-versa), there is still a possibility that the Oranje may meet the Selecao in the next round of the competition, yet van Gaal feels Luiz Felipe Scolari will do all he can in his power to avoid the Dutch in the next round.
"I can well imagine that Brazil doesn't want to face Netherlands," he said.
"We have scored a lot of goals. True. And we have we scored fantastic goals. True as well."
The Dutch face Chile in a top-of-the-table Group B clash at 6pm, followed by Brazil’s match-up versus Cameroon at 10pm.
