Overlap vs. Underlap: Understanding Attacking Runs in Football

An overlap is an attacking run where a player moves around the outside of a teammate, often a wide player, to create width. Conversely, an underlap involves a player running inside a teammate, typically a winger, to exploit central spaces.

Overlap

Coach

Short definition

A run made by a player on the outside of a teammate, typically to provide width.

Primary use

An overlap is ideal when you want to stretch a compact defense, create crossing opportunities, or isolate an opponent's full-back in a one-on-one situation. Think of a classic winger holding the ball, waiting for their full-back to burst past them.

Underlap

Coach

Short definition

A run made by a player on the inside of a teammate, typically to exploit central areas.

Primary use

An underlap is best employed to penetrate through the heart of a defense, create numerical superiority in the half-spaces, or set up cut-backs and shots from inside the box. It's often seen when a team wants to play intricate, quick passing combinations.

Side-by-side comparison

Criterion	Overlap	Underlap
Definition	A run made by a player on the outside of a teammate, typically to provide width.	A run made by a player on the inside of a teammate, typically to exploit central areas.
Primary Objective	To create space for a cross, draw defenders wide, or provide an option down the touchline.	To penetrate central defensive lines, create passing triangles, or open up shooting opportunities.
Typical Runner	Full-back or wing-back running past a winger.	Full-back, central midfielder, or even a wide forward running inside a winger.
Space Exploited	The wide channel, often near the touchline.	The half-space, which is the channel between the central and wide areas of the pitch.
Defensive Impact	Stretches the opponent's defensive line horizontally, forcing wide defenders to make a choice.	Disrupts the opponent's defensive shape vertically, creating dilemmas for central defenders and midfielders.
Ball Receiver's Role	Often receives the ball in a wide area, with space to cross or drive towards the byline.	Often receives the ball in a more central, dangerous area, with options to shoot or pass through.
Common Tactical Outcome	Leads to crosses from wide positions or one-on-one situations on the flank.	Facilitates intricate passing combinations, cut-backs, or direct shots on goal from closer range.
Risk Profile	Generally lower risk as it maintains width, but can leave space behind the runner if possession is lost.	Higher risk as it commits more players centrally, potentially exposing the team to counter-attacks if the ball is lost.

Advantages · Overlap

Creates width and stretches opposition defenses.
Provides clear crossing opportunities from deep or advanced positions.
Draws opposition full-backs out, creating space for other attackers.
Can be a simple, effective way to progress the ball up the flank.

Advantages · Underlap

Exploits dangerous half-spaces between defenders.
Creates numerical overloads in central attacking areas.
Opens up direct passing lanes into the box or for shots.
Disrupts compact defensive blocks, forcing central defenders to shift.

Limitations · Overlap

Can become predictable if overused, leading to easily defended crosses.
Requires good timing and communication to avoid running into offside positions.
If the cross isn't successful, possession can be easily lost in wide areas.
Less direct threat on goal compared to central penetration.

Limitations · Underlap

Higher risk of losing possession in critical central areas.
Requires excellent technical ability and spatial awareness from multiple players.
Can leave wide areas exposed defensively if the underlapping player is a full-back.
More susceptible to offside calls due to tighter defensive lines.

Real football examples

Let's look at how these attacking runs play out in real matches. For overlaps, consider the classic Liverpool setup under Jürgen Klopp. Trent Alexander-Arnold, the right-back, often makes blistering overlapping runs past Mohamed Salah. Salah might hold the ball wide, drawing the opposing full-back, and then release Alexander-Arnold into acres of space down the touchline to deliver a dangerous cross. This stretches the defense and creates high-quality chances from wide areas. It's about maintaining width and exploiting the flanks.

Overlap vs Underlap explained

Now, for underlaps, Manchester City under Pep Guardiola provides a perfect illustration. Their inverted wingers, like Jack Grealish or Bernardo Silva, often drift inside, creating space on the touchline. This allows their full-backs, like Kyle Walker or João Cancelo (when he was there), to make an underlapping run into the 'half-space' – that dangerous channel between the opposition's centre-back and full-back. This creates a numerical overload centrally, pulling defenders out of position and opening up passing lanes for a through ball, a quick one-two, or even a shot on goal. It's a more intricate, often riskier, but potentially more rewarding way to break down a stubborn defense, focusing on central penetration rather than wide delivery. It’s a key reason why City can dominate possession and create so many chances from inside the box. Another example might be the way Chelsea's Reece James sometimes underlaps to get into shooting positions, rather than always crossing from wide.

Frequently asked questions

?What's the main difference between an overlap and an underlap?

An overlap sees a player run *outside* a teammate to add width, while an underlap involves a player running *inside* a teammate to exploit central areas. It's all about whether the run is wide or narrow relative to the ball-carrying teammate.

?Which type of run is more common in modern football?

Both are prevalent, but the underlap has seen a significant rise in popularity, especially with teams that use inverted wingers or seek to dominate central areas. Overlaps remain crucial for creating width and crossing opportunities.

?Can a player make both an overlap and an underlap in the same game?

Absolutely. A versatile full-back, for instance, might be instructed to overlap when the team needs width, and underlap when the tactical aim is to penetrate centrally or create overloads in the half-spaces, depending on the game state and opponent.

?Do these runs only apply to full-backs?

No, while full-backs are common runners, central midfielders, wide forwards, or even centre-backs in certain tactical systems can make these runs. The key is the relative position of the runner to a ball-carrying teammate.

?What is a 'half-space'?

The half-space is the vertical channel on a football pitch located between the central corridor and the wide wing areas. It's often considered a highly dangerous zone for attacking teams to exploit because it forces defensive players into difficult decisions.
