This drill could be a mini form of a real game situation. It starts with a build up, posses the ball, transfer the play to the other side and forward, finish, then transition. The zone in the middle in this drill could be taken advantage of for multiple reasons. For example, only one player each team allowed in, the player in possession will have to make the cruyff turn, the defender doing the marking, or the player in possession is obliged to have the ball kept for some seconds while the defender in his back, and so on.
