BR - Line it up. Select a corner or go for power. Upper 90 or lower shelf. Get the ball up and over the wall and make the thing dip, swerve or knuckle. These are some of the thought processes of the free kick master.
The success rate is low, no matter if the restart is right outside the penalty area or some 40+ yards away from goal. Only players who can temper supreme skill with the laws of angular physics are able to produce something that confounds the wall and keeper alike.
