Our winger gets to the byline and nobody attacks the far post

I’d base the far winger’s movement on what the ball carrier can actually deliver and what is already occupying the box. If the winger reaches the byline with time to drive the ball across goal, the far-side winger should usually be thinking about attacking beyond the far defender. If the ball carrier is under pressure and the likely pass is backwards, holding a position outside the box may be more useful. The 9’s run matters too. If the striker attacks the front space, the far winger can arrive behind the back line rather than joining the same area. I’d coach it in a front-five practice and vary the wide delivery. The far winger has to read front-post cross, cut-back and recycled possession. The cue is not “back post every time”. It is: what space is the defence leaving because of the first runs? Good box occupation gives you different depths and different lines, not four players making the same movement.
