Watch any knockout-round match from this summer's tournament and you'll see it happen in real time: a pocket of grass opens up between the lines, a runner is a half-step late, the ball goes sideways instead, and the chance is gone. Space creation is the single most decisive — and most misunderstood — skill in modern soccer. It isn't about pace or raw talent. It's a perceptual skill that separates players who make defenses collapse from players who simply run around a lot.
