Thus, the free kick taker has several choices, including; either to curl the ball around the wall with finesse, to bend the ball around the wall using power, or to go over the wall although this lessens the likelihood of scoring close-range free kicks.

The s Brazilian star Didi invented the folha seca dry leaf which is nowadays commonly known as the knuckleball free kick, [8] notably used by modern day players such as Juninho whose technique has been emulated , [9] and Cristiano Ronaldo, where the ball would be struck with either no or a low amount of spin, causing it to swerve unexpectedly at a point near the goal. Curling can be an effective technique when taking corner s.

The ball gradually moves in the air towards the goal. This is referred to as an in-swinging corner. Occasionally, a corner-taker will bend the ball towards the edge of the penalty area , for an attacker to volley , or take a touch and then shoot. Curling can be used in passing. Effective passes from midfield to an attacking player are often the result of a curled pass around the defender, or long cross field passes are sometimes aided by the addition of curl or backspin.

This can be done with either the inside of the foot our outside of the foot. The outside of the foot may be used when a player is facing sideways and wants to use the dominant foot to make a pass.

This causes a rotating ball to form a whirlpool about itself, with one side's air moving with the ball and the other side's air moving against the ball.

This creates a difference in air pressure , and the ball deviates from its path as a result of this. The Magnus effect is named after German physicist Heinrich Gustav Magnus , who described the effect in It uses material from the Wikipedia article " Curl association football ".
