Kompany insists the reason Belgium had failed to show their true colours in the group stage - where they beat Russia, Algeria and South Korea - was that their opponents had played it tight.
The USA, however, played a much more open game in their round of 16 game in Salvador when Belgium had 39 shots as they secured their progression to the last eight with two goals in extra time.
Kompany said: "If Argentina decide to play their usual attacking game, we'll have a pretty good chance against them.
"You need two teams to produce an exciting match. The Americans tried to push forward. That's all we were asking for. It takes two to tango, and they wanted the same thing as us."
