Curl (association football)
Curl or bend in association football is a definition for a spin on the ball which makes the ball move in a curved direction. When kicking the ball, the inside of the foot is often used to curl the ball, but this can also be done by using the outside of the foot. Similar to curl, the ball can also swerve in the air, without the spin on the ball which makes the ball curl.

Freekick imitation
Often several players (red) will line up for a free kick, so as to mask their intentions to the defending team (blue).
Vanishing spray has been utilised in recent years to indicate the minimum distance for free kicks.
