Arsenal won the 2025/26 Premier League with 19 goals from corners, more than any team in the competition’s history. It wasn’t luck, and it wasn’t just good crossing. The real advantage comes from what happens in the six-yard box after the ball is struck.

For years, set pieces were treated as football’s lottery. You whipped the ball in, hoped your centre-backs won the header, and moved on. That view is now badly out of date.

Across the Premier League, dead-ball situations have become one of the most carefully engineered parts of the game. Clubs employ specialist set-piece coaches, study opposition marking schemes on tracking data and rehearse routines with the precision of an NFL playbook. The results are showing up in the numbers.

The dead-ball surge

By 1 May 2026, 26.9% of all Premier League goals that season had come from non-penalty set pieces, according to Opta Analyst. That was the highest share on its records, which go back to 2013/14. Corner goals were arriving at 0.48 per game, also a record. Two seasons earlier, the set-piece share was closer to one in five, according to Statswing.

In a league where so many matches are decided by a single goal, a jump of that size changes results. And it changes what clubs need from their analysts.

The big idea: delivery gets you in, it doesn’t win you the ball

The easy explanation is “better crossers”. It’s also the least useful one. At elite level, almost every team has a player who can hit a corner accurately. Delivery quality is a prerequisite, not a differentiator.

What separates the best set-piece teams is a chain of micro-tactics that turns a good ball into a clean chance:

Delivery: a ball into a tight, pre-agreed target zone.
Separation: screens, blocks and packed runs that free the target from their marker.
Goalkeeper isolation: bodies placed in the keeper’s path and line of sight.
Phase Two: a structure for winning clearances and shooting again before the defence resets.

Let’s take them in turn.

1. Delivery: the inswinger takeover

Even though delivery isn’t what separates the best teams, it has changed dramatically. Premier League data published in November 2024 showed inswinging corners rising from 47.6% of all corners in 2022/23 to 60.6% in the early part of 2024/25. Over the same period, outswingers fell from 31.4% to 18.8%.

The target has moved too. Corners are increasingly aimed straight into the six-yard box, the most crowded area on the pitch and the goalkeeper’s own territory.

Why aim for the busiest place on the pitch? Part of the answer is physics. A heavily spun inswinger curves towards goal and dips sharply late in its flight, because of the Magnus effect (the sideways force a spinning ball creates as it moves through the air). A ball that drops suddenly is much harder for a goalkeeper to judge than one that floats. Put that ball into a crowded six-yard box and the keeper has to decide whether to come for it while bodies block the way.

2. Separation: screens, packs and blocks

This is where elite routines start to look like basketball. Attacking teams now use screens: players whose only job is to stand in the path of a defender or the goalkeeper, soaking up their movement without making an obvious foul. That creates a small, short-lived pocket of space for the real target to run into.

The other common tool is the far-post pack. Four or five attackers start bunched together outside the back post, then break at speed in different directions as the ball is struck. Zonal defenders have to pass runners between them, and man-markers have to follow them through traffic. Both jobs get much harder when everyone moves at once.

Even when the target doesn’t win a clean header, all those bodies mean a flick or a deflection across the face of goal is often just as dangerous.

3. Goalkeeper isolation: take away what they can see

A goalkeeper who can’t move freely can’t claim the ball. Catching a cross needs a clear run and both arms free. With a screener standing on their line of movement, many keepers either stay on their line or settle for a one-handed punch, and a punch often creates exactly the loose ball the attacking team has planned for.

Goalkeeper analysis has changed to match. Save percentage alone says little here. Models such as StatsBomb’s xClaim give every ball into the box a likelihood of being claimed, so analysts can see whether a keeper collects more or fewer crosses than expected (reported as CCAA%). Tracking a keeper’s claim rate and punch frequency with and without a screener is one of the most revealing checks in opposition analysis.

Blocking the keeper’s view matters as much as blocking their movement. An analysis of around 30,000 shots from StatsBomb’s open data found that shots from around the box often beat their expected goals when players stood between the shooter and the goalkeeper, but only when no defender was pressuring the shot:

The lesson for set-piece coaches is simple. When a corner is only half-cleared to the edge of the box, the bodies still in the six-yard area are working as a screen. A shot that looks like a speculative strike becomes much harder to save.

The short-corner switch

If direct deliveries into the six-yard box are the headline act, short corners are the misdirection. They rarely lead to a goal straight away. Their value is in what they do to the defensive shape.

Put two players near the flag and the defence has to send someone out, or give away a free cross. Every defender who leaves the box thins out the structure inside. The cross then comes from a new angle, past the near-post zonal wall that was set up for a direct delivery. Meanwhile the defensive line has to step up and reset, and runners can attack the gaps that open up.

4. Phase Two: the corner doesn’t end at the first header

This is probably the most under-appreciated part of modern set-piece play. A cleared corner isn’t a failed corner if you win the second ball.

Top analysis departments track how often a set piece produces a shot within three passes of the first clearance. In that short window the defence is still disorganised: the line is broken, the offside trap is out of shape and space is opening up all over the box.

To make the most of it, the best teams place players around the edge of the penalty area during corners. Those players do two jobs at once:

Recycling: any clearance or punch lands in an area the attacking team already controls, ready for a shot or a second cross.
Rest defence: if the ball is lost, players are already in position to counter-press or stop a breakaway.

The defensive answer: hybrid set-ups

Defences have evolved too. Pure zonal marking is vulnerable to runners arriving at speed from a far-post pack. Pure man-to-man marking falls apart when screens separate markers from their runners. The most resilient structures are usually hybrids.

Three or four defenders hold zones in and around the six-yard box to deal with the dipping inswinger and protect the keeper. Man-markers stay tight to the biggest aerial threats and deny them a run-up. Increasingly, one defender’s job is simply to block the blocker so the screener can’t set a clean pick.

Research is catching up with this complexity. A January 2026 paper (Groom et al.) used a covariate-dependent hidden Markov model on tracking data to work out, frame by frame, whether each defender at a corner was marking a player or a zone, without anyone labelling the footage by hand. It then compared each defender’s actual position with where they should have been. For analysts, the takeaway is that “who was marking whom” is becoming something you can measure rather than just argue about in a video session.

Case study: Arsenal’s record-breaking season

No team shows these ideas better than Arsenal under set-piece coach Nicolas Jover. Their 19 goals from corners in 2025/26 beat the previous Premier League best of 16, a total that Arsenal themselves had matched in 2023/24. That was roughly a quarter of their 71 league goals in a title-winning season.

Arsenal’s approach uses every element covered above:

Inswingers from both sides. With Declan Rice delivering from one flank and Bukayo Saka from the other, Arsenal can use the same central structure whichever side the corner is taken from. At the start of May, seven goals had come from Rice’s corners alone, second only to Bruno Fernandes in the league (Opta).
Crowding the goalkeeper. Screeners stand in the keeper’s space while tall defenders such as Gabriel make blind-side runs away from zonal markers.
Packs and edge-of-box structure. Runners start in a cluster and break together, while players on the edge of the box split between attacking the far post and staying back as cover.
By May, Arsenal had taken more shots from corner situations (95) and generated more expected goals from corners (12.1) than any other side (Opta).

The approach hasn’t been without controversy. The line between a legitimate screen and illegally impeding the goalkeeper has been one of the most debated refereeing topics of recent seasons, and it’s something every analyst should watch.

Brentford: the pioneers who moved on

If Arsenal perfected the modern set piece, Brentford helped create it. The club built its identity on dead-ball detail, and in 2025 promoted Keith Andrews, previously its set-piece coach, to head coach.

Brentford’s clearest edge has been the long throw, and the tactic has spread quickly across the league.

Interestingly, Brentford’s 2025/26 goals leaned more on open play. By February, Opta had 72% of their league goals coming from open play, with only two from corners. That’s a useful reminder for scouts and analysts: a team’s set-piece reputation can lag behind what it’s actually doing, so always check the current data.

What analysts should actually measure

Counting set-piece goals won’t tell you much. They’re rare events with a lot of variance. If you’re analysing your own team or preparing an opposition report, these measures are far more useful:

xG per corner, split by delivery type (inswinging, outswinging, short) and by the defensive system faced (zonal, man-to-man, hybrid).
First-contact win rate: who gets to the ball first, and in which zone.
Goalkeeper claim rate and punch frequency, compared with and without a screener.
Second-ball shot rate: the share of set pieces that produce a shot within three passes of the first clearance.
Defensive role mapping: who is zonal, who is man-marking and who is blocking, and where the gaps appear when a short corner pulls players out.
Target-zone accuracy: how consistently the taker hits the agreed area, not just whether the ball beats the first defender.

What comes next

Two forces will shape the next few seasons.

Regulation. Screening will stay under the spotlight as referees judge whether blockers are genuinely trying to play the ball. IFAB has also introduced a five-second visual countdown for throw-ins and goal kicks that the referee thinks are being delayed, part of the Laws of the Game from 1 July 2026. The countdown doesn’t apply to corners, but it does apply to throw-ins. That could squeeze elaborate long-throw routines, which often rely on taking time to get big players forward.

Simulation. The next step is modelling. Instead of only reviewing what happened, analysts will increasingly test what would have happened if a runner had started a metre deeper or half a second later. Rebounds and deflections are still very hard to predict, but the direction is clear.

The takeaway

Set pieces have gone from an afterthought to one of the most carefully designed phases of football. The ball into the box still matters, but it’s only the entry ticket. The real edge is in the screens, the runs, the goalkeeper’s sightline and the fight for the second ball, and in analysts who can see and measure all of it.
