The half-space is worthless unless somebody is standing on the touchline

A word that took over tactical writing describes a zone which only exists when a completely different player does his job.

The half-space is the strip of grass between the centre of the pitch and the touchline, roughly where the edge of the penalty area extends upfield. Split the pitch into five vertical lanes and it is the second and fourth. Fine. Useful vocabulary, up to a point.

The reason it is a good place to receive the ball is geometric. Stand there and you can see the goal, you can play a through ball inside or a cross outside, and you are in the seam between a centre-back and a full-back where neither is quite sure whose job you are. Everyone knows this now. It is in every coaching course and half the transfer scouting reports.

Here is the part that gets skipped. That seam only exists if the full-back is being pulled away by somebody outside him. If nobody is holding the width, the full-back simply narrows, stands next to his centre-half, and the half-space stops being a seam and becomes just another crowded bit of the middle. You have not found a clever pocket. You have walked into a two-versus-one and are about to lose the ball.

Which makes the winger on the touchline, the one who touches the ball nine times all half and gets criticised for being anonymous, the entire reason the clever player in the pocket looks clever.

That relationship is why so many sides look sharp for twenty minutes and then congested. The half-space player gets the ball, does something nice, and the touchline player drifts inside because that is where the game is. Now both are in the same lane. The pitch is suddenly forty metres wide. Every pass is into traffic, the block has nothing to stretch it, and a manager on the touchline is shouting a word that sounds like stay.

The good sides police this obsessively. You will see a coach abusing a winger who has drifted five metres infield while the ball is on the far side, and it looks like unreasonable micromanagement of a player who is not even involved. It is not. He is the reason the move on the other flank has room.

So my mild complaint about the language: half-space gets used as though it names a talent. It does not. It names a piece of ground that somebody else is generously keeping open, usually a wide player doing thankless work, and if you are handing out credit for a goal that started there, save some for him.
