The picture above is of a training drill, which involves four players i.e. player A, B, C and D and finishing the drill by scoring the goal.
The drill starts when the Player A passes the ball to the Player D who receives the ball and after rolling it in a zig-zag path, shoots it in the bottom left corner to score the goal. After this, the Player B passes the ball to the Player D who upon receiving the ball again rolls the ball in a zig-zag path, before shooting it at the bottom right corner to score. At the end, the Player C plays a minus ball to Player D who shoots the ball at the first contact, in the top right corner in order to score the goal and finally concluding the drill.
This drill is very useful in improving the shooting and finishing of a player which are of prime importance for the strikers to win the games for their teams.
