Playing between the lines means occupying or receiving in the space between the opponent’s defensive units, usually midfield and defense. The space can be central or in a half-space.
What to watch
A useful receiving position depends on the passing lane, timing, body orientation, and pressure. A player standing in a gap is not necessarily available if a defender blocks the pass or can close down immediately.
An illustrative example
An attacking midfielder checks away from a marker, receives behind the midfield line, and turns toward goal. If turning is unsafe, a first-time layoff may help a teammate move the attack forward.
Avoid this mistake
A broadcast camera may hide supporting runs or covering defenders. Describe the visible receiving action before claiming that the entire defensive structure was broken.
