Van Gaal admitted that he used the tournament's first cooling breaks to help his side pull off their dramatic victory.
"He's maybe the best tactically there is in the world," Kuyt told Sport24.
"It doesn't matter what system we are playing the players know exactly what to do. He told us before the game already that we could switch system if we were 1-0 down.
"We switched to 4-3-3 then 15 minutes before the end of the game he decided to put an extra striker to play longer balls and looks for second balls and we managed to score a goal so his tactics were once again spot on."
Netherlands will play Costa Rica in the last eight on Saturday.
