What is an overlapping full-back in football

The overlapping full-back is the most underrated attacking weapon in modern football, because the player who makes the run so rarely gets the ball. The overlap is a decoy as often as it is a delivery: the full-back sprints beyond his winger into the space behind the defence, and the value of that sprint is what it does to the opposition full-back, who is forced to decide between following the runner and staying with the winger. The winger ends up with the assist and the credit, but the run that created the room belongs to the defender. Every Premier League club that plays with width is quietly built on this move, and the numbers from 2024/25 show it is not going away.

What is an overlapping full-back?

An overlapping full-back is a full-back who makes forward runs beyond the winger or wide midfielder on his side of the pitch. The mechanics are simple: the winger holds the ball, the full-back sprints past him on the outside, and the winger plays the ball into the space the run has created. The run can end in a cross, a cut-back, a through ball or a switch of play, and the full-back can also run onto through balls delivered by the central midfielders.

The overlap is the opposite of the underlap, where the full-back runs inside the winger into a central position, and it is the older and simpler of the two movements. It is the original way a team gets width from its defenders: instead of relying on wingers hugging the touchline, the team lets its wingers drift inside and asks the full-backs to provide the width. Mo Salah is the model example, a winger who takes narrow positions while his full-back provides the wide outlet on that flank.

Why the overlap matters

The value of the overlap is not the run itself but the reaction it forces. When a full-back overlaps, the opposition full-back must decide whether to track him or stay with the winger. If he tracks the runner, the winger is free to cut inside onto his stronger foot. If he stays with the winger, the overlapping full-back receives the ball in space with time to cross. The defence is forced to split its attention, and that split is where the chance comes from.

The overlap also creates overloads in wide areas. A team that commits its full-back forward alongside the winger has two attackers against one defender on that flank, and the extra man is what turns a dead-end wide position into a crossing opportunity. This is why overlapping full-backs have become integral to success at the highest level: they are the simplest way to manufacture a numerical advantage without changing the formation.

The origins: Brazil's flying full-backs

The overlap as a defining tactical idea was perfected in Brazil, where the full-back was always treated as an attacking position. Roberto Carlos and Cafu are the prototypes of the modern full-back, two players whose relentless overlapping runs terrorised opposition defences for a decade. Cafu's rise began at Sao Paulo, where Telê Santana suggested he move from right midfield to wingback, a switch he made with ease despite never previously playing the position, and he went on to play in three consecutive World Cup finals, the only player ever to do so. Roberto Carlos, famously used on the wing and even in midfield during an unhappy year at Inter Milan, was sold to Real Madrid in 1996 and blossomed into the best left-back in the world, winning four league titles and three Champions League trophies.

Their peak together came at the 2002 World Cup, where Brazil's famous front three of Ronaldo, Rivaldo and Ronaldinho tormented defences while Carlos and Cafu bombed forward from the full-back positions behind them. The football writer Jonathan Wilson once observed that every World Cup since 1994 has been won by the team with the best pair of attacking full-backs: Jorginho and Branco in 1994, Thuram and Lizarazu in 1998, Cafu and Roberto Carlos in 2002, Zambrotta and Grosso in 2006. That pattern is the strongest possible evidence that the overlap is not a gimmick but a core principle of how modern teams attack.

The Premier League record-holders

The Premier League's history of overlapping full-backs is essentially the history of Liverpool's left and right sides. Trent Alexander-Arnold holds the record for the most Premier League assists by a defender with 64, achieved between 2016 and 2025, and he regained the outright record from his own clubmate Andy Robertson with two assists against Newcastle in December 2024. Alexander-Arnold also holds the single-season assist record for a defender, setting up 13 goals in 2019/20.

The 2018/19 season was the moment the role stopped being a curiosity. Alexander-Arnold set up 12 goals, the most by a defender in a single Premier League season, eclipsing the 11 set by Robertson, Leighton Baines and Andy Hinchcliffe. Robertson and Alexander-Arnold became the first set of defenders from the same team to record double figures for assists in the same season. Those numbers were not just records; they were the engine of a Liverpool side that used its full-backs as its primary creators. By 2019/20 the same machinery, a high-pressing 4-3-3 with the full-backs as creators, delivered the Premier League title with 99 points.

The modern exponents: Trent, Robertson and Robinson

Alexander-Arnold's importance to Liverpool was never just the assists. He leads the Premier League for successful crosses (481) and passes into the box (2,602), figures that apply across all positions, not just full-backs. In 2024/25 he recorded six assists, topped among full-backs only by Antonee Robinson and Wolves' Rayan Ait-Nouri, and his 7.4 expected assists from completed passes was the best in the league.

Robinson, Fulham's left-back, is the best current example of the overlap as a full-season weapon. In 2024/25 he ranked first among all Premier League full-backs in both assists (10, four more than Alexander-Arnold) and defensive interventions (496), and second in progressive carries with 284, trailing only Manchester City's Josko Gvardiol. Robinson showed that the modern overlapping full-back must do both jobs: get forward to create, and cover the space he leaves behind when he does. Fulham's overachieving season was built substantially on his flank, and his 10 assists were more than attackers like Marcus Rashford, Phil Foden, Cody Gakpo and Kai Havertz managed.

The risks of the overlap

The overlap is not free. When a full-back goes forward, the space behind him is exposed, and a team that commits both full-backs leaves its centre-backs isolated against fast attackers on the counter. The modern full-back must be extremely fit to cope with offensive and defensive transitions, and full-backs who cannot chase back get exposed defensively. This is the trade-off every coach accepts: the overlap creates chances at the price of defensive vulnerability, and the best teams manage that risk by timing the runs and covering the space when the ball is lost.

Key takeaways

• An overlapping full-back runs beyond the winger on the outside to provide width and create overloads, and the run often matters more than the delivery.
• The overlap forces the opposition full-back to choose between tracking the runner and staying with the winger, which is where the space comes from.
• Roberto Carlos and Cafu perfected the role and Brazil reaped the rewards, including the 2002 World Cup.
• Trent Alexander-Arnold holds the Premier League records for most assists by a defender (64), most in a season (13) and most successful crosses (481).
• Antonee Robinson was the most productive full-back in the league in 2024/25 with 10 assists, showing the role is alive at the top of the Premier League.

FAQ

What is an overlapping full-back?

A full-back who makes forward runs beyond the winger or wide midfielder on his side, going outside him to provide width, cross, or run onto through balls. It is the opposite of the underlap, where the full-back runs inside.

Who are the best overlapping full-backs in history?

Roberto Carlos and Cafu are the prototypes, and Trent Alexander-Arnold holds the Premier League records for a defender. Andy Robertson and Antonee Robinson are the modern English examples.

What is the difference between an overlap and an underlap?

An overlap is a run outside the teammate in possession, into the space beyond him. An underlap is a run inside the teammate, into a more central position. The overlap provides width; the underlap attacks the centre.

How many assists does Trent Alexander-Arnold have in the Premier League?

64, the most by any defender in the competition's history, achieved between 2016 and 2025. He also holds the single-season defender record of 13, set in 2019/20.

Do overlapping full-backs still work in the modern game?

Yes. Antonee Robinson ranked first among Premier League full-backs for assists in 2024/25 with 10, and the tactic remains the simplest way to create overloads and stretch a defence, provided the full-back has the stamina to recover.
