Deus, this drill is about your pressing angle as a lone striker.

Setup

The grid is 12 meters long and 6 meters wide, split into two vertical corridors of 3 meters each.

The goalkeeper is outside the rectangle, behind the center backs.

Each center back starts inside the rectangle, one in each corridor.

They are already locked to their side.

Play is live from the first pass.

The center backs can:

pass to each other,

pass back to the goalkeeper,

and receive the ball again.

The goalkeeper can play to either center back.

Trigger

The moment a center back carries the ball forward past the entry line in their corridor, play becomes directional.

From that moment:

the ball must stay in that corridor,

the other center back stays in their own corridor,

the attacking team must progress forward on that side.

Reaching the end zone = goal.

Your job

When a center back has the ball, do not run at the ball.

Your reference is the far shoulder of that center back.

Picture a straight line from your eyes to that far shoulder.

That line decides your run.

You stay on that line the entire press.

If you stay on that line:

the passing lane back to the goalkeeper is closed by your body position,

the center back cannot switch play,

the ball is forced forward in one corridor,

the next pass becomes predictable for your team.

That is success.

You do not need to touch the ball.

Failure

If you run directly at the ball or the near shoulder:

the passing lane to the goalkeeper stays open,

the center back plays back,

the goalkeeper switches sides,

the opposite center back progresses with time,

they reach the end zone.

That is failure.

Why the space is small

The space is small so mistakes cannot be fixed.

There is no time to curve your run late.

There is no recovery sprint.

Your first step decides the rep.

This drill isolates one thing only:

your pressing angle.

Nothing else.
