The full-back who leaves the door open 🔓

Watch Milan's right side in the first half against Lecce. Mario Gila, a centre-back by trade, pushes high as a right-back in possession. That leaves Chukwueze free ahead of him, but it also vacates the channel behind.

Lecce never punished it. The space between Gila and De Winter stayed empty because the visitors' striker dropped too deep. That gap is the first thing a better side attacks.

When Amorim switched to a back four, the whole chain changed. Gila could step out without leaving a hole. The full-back role only works if someone covers the lane he abandons.

Look at who fills the space when the full-back goes.

Question: Where does the nearest midfielder stand when your team's right-back pushes forward?
