Defenders need strong tackling and positioning skills to protect their goal. Shadow defending is an excellent way to practice. Pair up with a teammate, and for 2 minutes, mirror their movements as they try to dribble past you. Repeat this exercise 5 times, alternating roles. In one-on-one challenges, practice clean tackles by taking 10 turns as both the attacker and defender. Focus on timing and proper body positioning to avoid fouls. Include these exercises in your routine 2-3 times a week, and your defensive skills will improve significantly within a month.
