Marking opponents effectively is a key defensive skill. For this drill, pair up with a teammate. The attacker dribbles the ball within a 10x10 meter square, while the defender focuses on maintaining a close distance without fouling. The goal for the defender is to shadow the attacker for 30-second intervals without letting them break free. Repeat this drill 8-10 times, alternating roles. For advanced practice, add a third player acting as a passer, requiring the defender to track the attacker while intercepting passes. Perform this drill twice a week to enhance your defensive positioning and ability to read an opponent's movements.
