Soccer has so many positions and roles on the pitch that it’s more than natural to have doubts. Sometimes, position names may not even make much sense (the same happens in other sports).

If you’re wondering: “what is a fullback in soccer” or “what is the job of a fullback” I’ve got you covered. After all, this is my number one sport, and fullback is one of my favorite positions in association football.

A fullback in soccer is a defender who plays wide on the right or left side of the defensive line — thus being called right-back or left-back. While their main job is stopping opposing wingers and forwards, in modern soccer, fullbacks are vital in the attack by supplying crosses and making assists.

The above fullback definition already says a lot, but allow me to expand on it a bit more so you can fully understand the role and responsibilities of a fullback in soccer and much more.

What Is a Fullback in Soccer?

A fullback in soccer is a wide defensive player who plays outside of the center backs on either side of the pitch.There are two fullbacks on each team, a right-back and a left-back.

Fullbacks are used in different types of player alignments, but mainly in the 4-3-3, 4-4-2, and 5-4-1 formations.

The primary focus of a fullback is the defensive duty.

They defend the outer edges of the pitch, marking the opposition winger, preventing/stopping crosses, and winning defensive duels in wide areas.

They also provide cover when the ball is on the opposite side of the field and close in the center and midfield when center backs or midfielders are beaten, overtaken or not present.

Their secondary function is to support the midfield and the attack.

Fullbacks offer attacking support to the midfielders, wingers, and forwards. They do offensive counter attacks from the wings, make overlapping/underlapping runs and deliver crosses into the box.

Being a successful fullback requires a specific set of skills: speed, stamina, endurance, strength, and being able to excel at defense and create disruption while attacking.

Over the past 15 to 20 years, the role and importance of a fullback has evolved, becoming one of the most demanding and critical positions in soccer.

In today’s game, it plays a crucial role as it contributes significantly to a team’s success. And in the future the impact of this position will become even greater.

What Are the Duties of a Fullback?

Now that we know what a fullback is, another question comes to mind: “What does a fullback do?”.

As an integral part of any football team, a fullback has plenty of roles and responsibilities in all the sectors of the field: defense, midfield, and attack.

Let’s explore what they are.


As a defender, the primary role of a fullback is to prevent the opponent from scoring.


When defending, they spend most of their time on their team’s half of the pitch.

They mark the opposing player (be it a winger, forward, midfield, or any player that moves closer to them).

While marking the opposing player, a fullback closes in and pressures them, giving them the least room to move around or dribble.

At the same time, they should be aware that a through pass or a ball push into the space behind their backline could put their team in danger.

In a 1vs1 situation, a fullback should tackle or otherwise try to steal the ball from the opponent. In that case, they should be mindful not to rush into it at the expense of getting dribbled or overtaken.

High Pressing

Some coaches prefer to use high pressing in the defensive phase.

That means that the backline will be very forward up the field and that both fullbacks need to be closer to the opposing midfielder, winger, or fullback.

This will leave a lot of empty room behind the defensive line.

If there’s a pass into the space over the backline, the fullbacks (and the backline) need to quickly move down and defend their goal.

While maintaining high pressure, the coach can ask the fullbacks to anticipate/steal the ball from their direct marker and initiate the offensive transition.


When in possession and with the center of the game (ball’s location) on the other side of the field, and/or when the other fullback is moving up the pitch, a fullback should close in the center to participate in an eventual defensive transition.

When the ball possession is lost while the fullback is forward up the field, they need a speedy possession-lost reaction.

In that scenario, a fullback needs to pressure/move down the field as fast as possible to stop the opponent from taking advantage of their advanced position and the space left behind their backline.

Supporting Midfielders and Attackers

Another crucial responsibility of a fullback is to support midfielders and attackers.

This entails covering spaces left behind by attacking players and being available for a pass when needed.

Proper positioning and anticipation are essential for effectively providing this support, allowing the player to quickly close down opponents and maintain possession.


Fullbacks also contribute to their team’s attack.

A key aspect of this attack-support role is to use the ball effectively by creating width, pushing higher up the field, and delivering crosses into the penalty area.

The goal is to create scoring opportunities for the fowards and offensive midfielders by providing accurate passes and crosses.

In the construction phase, a fullback should be a passing option for center-backs and midfielders.

To do so, their position on the field may vary:

  • They can be the player on the sideline in a three-at-the-back construction play.
  • They can move inside and provide an interior passing line.
  • They act as a winger, moving closer to the opposing team’s last line of defense and giving the winger freedom to receive a pass in the center.

When possible, the fullback should try to create 2vs1 situations close to the sideline.

This is achievable with:

  • Overlapping forward runs: going behind the winger or wide midfielder.
  • Underlapping forward runs: going in front the winger or wide midfielder in a breakthrough movement between the opposing fullback and center-back.

In possesion while inside the opponent’s half of the field, fullbacks can be asked to:

Act as a pure winger, positioning themselves by the sidelines in the last third of the attacking half of the pitch.

The real winger will move inside and the fullback will wait for the ball to start an offensive 1vs1.

Attacking Structure

More and more coaches are positioning one of the fullbacks in the center in the construction, creation, and finishing phases.

The fullback in the inside acts as a midfielder helping the team build up their attacking play.

If the possession is lost in the central channel (middle of the pitch), this fullback works an extra defensive midfielder.

In this type of offensive strategy, the other fullback will be positioned by the touchline ready to explore the depth (stretch the opposition defense), battle in 1vs1 plays and cross into the box.


Communication is paramount for success in any position, especially for a fullback.

Constant communication with teammates, particularly defensive partners, is crucial to ensure solidarity and coordination on the field.

This helps maintaining a strong and cohesive defensive unit, as well as make sure everyone is prepared to transition between attacking and defending phases effectively.

When possession is lost, they close in in the center of the midfield or touchline or run back to strengthen the backline.

All of this provides the coach with more strategic options and tactical solutions to quickly react to the flow of the game.
