It is important to stress to all your players that when they are going
for distance, or want a high-crossing ball, they must always kick a
moving ball, never practise kicking a stationary (dead) ball — only do
this for practising corners and free kicks.
The technique you
need to teach your players for long kicking starts with them pushing
the ball to the side, slightly in front of the body.
Kick
through the ball
If your player is right-footed get him to place
the left foot alongside the ball, keep his head down looking at the
ball and kick through the centre of the ball. He should be trying to get his toe
under the ball and with a tight ankle joint, his body leaning slightly
back, kick through the ball.
Make sure your players only lift their head after
contact.
Practise this soccer drill with three players A, B and C. B passes
into A who kicks long to C. C back to B. Each player swaps places with
the person they passed to.
