Clear the danger with a dominant defensive header. Attack the ball to beat the attacker to it, head through the middle with the forehead, and clear it high and wide toward the touchline, never back across goal.
A server crosses flighted balls into the penalty area; a defender moves off the line, attacks the ball, and clears it high and wide before it can drop. Add an attacker to contest the header. Insist on height and distance to the touchline, never a header back across the goal. Rotate servers and defenders.
Fork it into your private drills, then change the animation, adjust positions, swap equipment, or drop it into a session block.
