The picture above is of a training drill. It involves players from two teams i.e. Team Red and Team Blue and the goalkeepers.
The drill starts when the goalkeeper at the lower side of the picture passes the ball to the Player at Spot A, who after receiving the ball dribbles the ball. The Blue player at spot B now acts as a defender and moves forward in order to steal the ball away from the Red player. The Red player has two dribble the ball away from the Blue player and shoot at the goal to score the goal where the goalkeeper is also ready to save the shoot.
These type of drills help the players to practice shooting and dribbling the ball, which can be very useful in real match scenarios.
