Guardiola notoriously painted his training pitches with a grid of 20 zones. The golden rule was that no more than two players could occupy the same vertical line, and no more than three could be on the same horizontal line. This forced the team to maintain a perfect spread across the pitch. If a winger cut inside, a fullback or midfielder instinctively rotated to fill the wide space.

Classic near-post corner — inswinging delivery met by designated flicker with glancing header, redirecting across the goal face for far-post runner to finish. GK wrong-footed by the change of direction
