KINETIC ENERGY: The work done by an external force to bring the body from rest to a particular state of motion.
WORK: The amount of energy transferred to or from a body or system as a result of forces acting upon the body, causing displacement of the body or parts of it. More specifically the work done by a particular force is the product of the displacement of the body and the component of the force in the direction of the displacement.
Therefore, for your example - the KICKER does the work on the ball (i.e. the ball moves in the same direction as SOME of the force applied to it).

actually according to the newtons third law of motion , to every action there is an equal and opposite reaction ,
using this law the kicker as he kicks the ball, does the work and at the same time makes the ball do the work by making it travel a distance away from its initial position

If I remember corrrectly work equals force x distance. The kicker is the source of the force and thereofer perfoms the work

Think about it this way.Who loses energy?-----The kicker right?.So work is done by the KICKER on the ball.As such the kicker performs work
