Most defenders are taught positioning.

Where to stand.
How to hold the line.

But at higher levels, that is not what decides these moments.

Body shape is.

This video breaks down why square body positioning creates delays, why it makes you vulnerable to balls in behind, and how attackers recognize and punish it instantly.

The key shift is simple.

Go side on early so you can see both the ball and the player and react without delay.

That is the difference between reacting late…

and controlling the situation from the start.
