Understanding the difference between overlapping and underlapping runs

The difference between the two runs

A run on the outside of a teammate with the ball on the wing, closer to the touchline, is called an overlap. A run on the inside, closer to the centre of the pitch, is called an underlap. The purpose of both is to give the ball carrier a passing option and to distract the opponent. Neither run is inherently better; it depends on the position and the defensive shape.

When overlapping, the runner provides width, which often creates space for the ball carrier to come inside. When underlapping, the runner can test the gap between the wide defender and the centre-back, while the ball carrier can find space on the outside. However, if there is already a teammate in that inside channel, another run can clog the lane. When choosing a run, you must also consider the positions of your teammates.

Timing and body position of the ball carrier

When the ball carrier has his head up and is in a position to pass, if the runner accelerates, it's easier to time the run. If the ball is still being controlled or the carrier is facing his own goal under pressure, running too early can mean the runner passes the space without receiving the ball. Sometimes the runner must wait a moment before accelerating. That wait is not a weakness; it's part of the combination play.

Even if the ball is not played to the runner, the movement can still be useful. If the defence tracks the runner, the ball carrier can come inside and pass or shoot. If the defence does not track, the runner can receive the next pass. So the success of a run should not be measured only by how many times the ball is received. You need to look at how the defence moves.

Who covers the vacated space?

When the full-back makes an overlapping run, his starting position is often left empty. A nearby midfielder staying deep, or a centre-back shifting slightly wide, can protect against the counter-attack. If players overlap on both flanks at the same time, the holding midfielder's responsibility increases. You have to weigh the added attacking options against the distance needed to recover defensively.

As a viewer, first identify whether the supporting player runs outside or inside the ball carrier. Then observe before the run: is there space between the two defenders, can the ball carrier pass, and is there cover behind? When you see these factors together, you will understand that overlaps and underlaps are not just aesthetically pleasing runs but movements that force the opponent to make choices.

Further points to observe when watching a match

The underlapping runner does not have to be the full-back. A nearby midfielder can make an inside run and offer an option to the wide player. In that case, the full-back can stay behind and be ready to recycle the ball and provide cover if possession is lost. More than the name of the run, the distribution of responsibilities — who runs and who covers — changes the security of the attack.

If the defence does not track the overlapping runner and instead hands off marking between themselves, a single overlap may not open up space. In that situation, rather than forcing a forward pass, the ball carrier can link play backwards and choose a new position. Don't assume every unsuccessful run means the runner was slow; also look at how the defence coordinated. The value of an attacking tactic is always linked to how the opponent responds.
