The concept of advanced collaboration with the defender is an evolution of simple collaboration with the defender, in this case observing the distance between the defender and the attacker.
Although the defender’s responsibility is always to ensure that the ball is not crossed, the goalkeeper can go further by observing if the thrower gets too close to the defender. In this case, especially in the case of arm shots that are too far away from the body or rectified, the thrower will probably want to cross the ball.
