Klinsmann has recently received praise after his side finished runners-up in a group comprising of Germany, Portugal and Ghana respectively.
However, Van Buyten claims to be unimpressed by the German's coaching methods and refuses to buy into his pre-match posturing ahead of the last-16 clash in Salvador.
"I am not impressed by Klinsmann. He is just a coach who knows how to conduct his group and get the maximum out of them by motivating them. The USA will certainly be organised," he told reporters.
"He talks a lot about us, saying that we are favourites, but I think he thinks otherwise.
"They will be motivated and want to do everything possible to go into the quarter-finals. But that will also be the case for us."
Tuesday's encounter is scheduled to kick off at 9pm.
