Lay out 6 cones in a line. Keeper skips through the line, then turns towards the thrower/kicker, and makes the save. Alternate after three goes.
The ball can be thrown or kicked depending on the skill level. The important feature of this exercise is footwork, and making the save.

Tips for coaches – Confidence Cohesion Technique
Any coach can utilize these drills with their keeper. The objectives are the same – enhance footwork, follow the ball better with the eyes, and judge the flight of the ball.
A coach can use any one of the drills independently, and involve multiple players, especially attackers, to sharpen their skills too.
Employ 1v1 in your regular practice sessions – this will help your strikers as much as your keeper, and keep it “real” for the keeper.
Try to encourage the keeper to use these skills – their footwork, their eyes and reflexes, and be brave to make the judgement calls and decisions that will come up regularly in games.
