M23 Derby: How the Glasner Revolution Rewrote the Crystal Palace vs Brighton Rivalry

A 94th-minute winner at the Amex Stadium in February 2026 captured something that had been building for two years. Crystal Palace, the side that had limped through much of the mid-2020s in a state of tactical uncertainty, travelled to their most disliked neighbours and left with three points after a 3-2 victory. It was the kind of result that rewrites recent history and reinforces a new narrative: the M23 derby no longer belongs to Brighton.

That outcome was not an accident. It was the product of a sustained period of reconstruction under Oliver Glasner, whose arrival at Selhurst Park in late 2024 began shifting the dynamic between these two clubs in ways that the February 2024 derby had made seem almost unthinkable. Back then, Brighton dispatched Palace 4-1 at the Amex in a manner that felt definitive. It ended Roy Hodgson's second spell in charge and left the Selhurst faithful with a sobering reminder of where they stood relative to a side that had been playing European football at the Amsterdam Arena.

For Palace supporters of a certain vintage, that European chapter for their rivals was a particularly uncomfortable period to live through. Brighton, the club from 50 miles down the road, had been competing on the continent while Palace navigated the familiar terrain of mid-table respectability. The 4-1 result was not simply a heavy defeat; it was the derby expression of a gap that had been widening for some time. Football rivalries are rarely fair, and for a stretch of time, this one felt distinctly one-sided.

The Road Back: How Glasner Changed the Calculation

Oliver Glasner's influence on Crystal Palace has been one of the more compelling managerial stories in the Premier League over the past two seasons. His approach brought tactical coherence, improved pressing structures, and crucially, a sense that Selhurst Park was no longer simply a place for opponents to bank comfortable wins. The effects on the M23 derby were not immediate, but they were consistent.

The December 2024 fixture at Selhurst Park produced a 2-2 draw, a result that felt significant not for the points shared but for the manner in which Palace competed. Gone was the defensive fragility that had defined the 4-1 capitulation earlier that year. In its place was a side willing to trade blows, capable of responding to setbacks, and organised enough to deny Brighton the kind of space that had made that February afternoon so damaging. Pressing with purpose rather than desperation is a distinction that separates organised sides from reactive ones, and Palace were beginning to show which they had become. Three months later, a 1-1 draw at the Amex in March 2025 reinforced the sense that something had genuinely changed. Palace were no longer turning up at Brighton's ground simply hoping to survive.

The November 2025 home victory, a 1-0 win at Selhurst Park, confirmed the shift. It was narrow, hard-fought, and entirely representative of what this fixture has become under Glasner: a contest decided by fine margins rather than the kind of gulf that the 4-1 scoreline had suggested was permanent.

February 2026: A Thriller That Defined an Era

Of all five meetings in this recent sequence, the February 2026 fixture at the Amex stands apart. A five-goal game that swung back and forth before Palace scored a winner in the fourth minute of added time is the kind of afternoon that gets lodged permanently in supporter memory. For Brighton fans, it was a painful conclusion to a match they might reasonably have expected to control on home turf. For Palace supporters, it was the exclamation mark on a two-year journey from humiliation to genuine competitiveness.

What makes that result particularly meaningful in the broader context of this rivalry is where it was won. The Amex Stadium had been a hostile environment for Palace, most memorably in February 2024 when Hodgson's side were taken apart in a performance that exposed every weakness the squad had. To return to the same ground two years later and claim a last-gasp win speaks to the organisational progress Glasner has delivered. Away performances at difficult venues require more than individual quality; they require a team that trusts its structure under pressure, and the ability to score in the 94th minute rather than concede in it is perhaps the clearest possible measure of that trust. Palace clearly had it in abundance.

It is also worth noting what this sequence of results means tactically. Brighton, under various managers across this period, have remained a side built on positional play, high lines, and technical quality through midfield. The fact that Palace have been able to neutralise those qualities across two draws and then exploit them for back-to-back victories suggests Glasner has found a reliable tactical answer. A high defensive line invites the press and punishes slow transitions; that Palace are now winning matches at the Amex in added time suggests they have learned to be patient against such setups before striking late. Two years ago, that answer did not exist.

Beyond the Football: The Robert Eaton Memorial Match

For all the intensity that defines this fixture across ninety minutes, there is a dimension to the Palace and Brighton relationship that exists entirely outside the results. The Robert Eaton Memorial Match takes place annually in memory of a Brighton supporter who died in the September 11 attacks in New York. Each year, fans of both clubs set aside the hostility of derby week to raise significant sums for youth sport.

One supporter described it as a "Christmas Day truce" in a conflict that otherwise never pauses, and it is a remarkably apt description. The event draws genuine participation from both sets of fans, which makes it unusual in the landscape of English football rivalries. There are few fixtures where supporters of opposing clubs will spend one afternoon fundraising together and then return the following Saturday to fierce antagonism. It speaks to something important about the human core of local football: even the most bitter neighbours can find common ground when the occasion calls for it.

The Robert Eaton Memorial Match has reportedly raised tens of thousands of pounds for youth sport projects over its history, a legacy that neither set of fans would trade regardless of what happens at the Amex or Selhurst Park. It is a rare and admirable tradition in the modern game, and one that quietly complicates any attempt to reduce this rivalry to simple hostility.

Geography, Identity and Why This Rivalry Matters

To an observer from outside the south of England, the M23 derby can appear puzzling. Palace and Brighton are not neighbours in the way that, say, Manchester United and Manchester City share a city. They are separated by the better part of an hour on the motorway, and yet the animosity between their supporter bases is entirely genuine and deeply rooted.

Part of the explanation lies in football geography. In a region of England that has historically lacked the density of top-flight clubs found in the north and Midlands, Palace and Brighton occupy similar space in terms of territory, ambition, and identity. Both clubs draw from overlapping catchment areas across Surrey and Sussex. Both have spent decades oscillating between Premier League consolidation and the threat of slipping back into the Championship. That shared precariousness breeds competition in a way that proximity to a wealthier rival, such as Arsenal or Chelsea, never quite could. When two clubs are fighting for the same supporters, the same local identity, and often the same league position, the stakes of every meeting feel disproportionately high.

The recent period of Brighton's European adventure briefly altered that dynamic, creating an uncomfortable gap in achievement that Palace fans were forced to acknowledge. The Glasner era has closed that gap considerably, and while Brighton remain a well-run, progressive club with genuine quality throughout their squad, the days of Palace simply arriving at this fixture as the weaker party appear to be over.

Verdict: A Rivalry Rebalanced, A Story Still Being Written

The five meetings between February 2024 and February 2026 tell a clear story of recalibration. A crushing 4-1 defeat that ended a managerial era gave way to two competitive draws, a narrow home win, and finally a dramatic away victory at the ground where it all went wrong. That arc is not coincidental. It maps directly onto the Glasner tenure and the structural improvements he has delivered at Selhurst Park.

What Palace have rediscovered in this period is the capacity to be genuinely uncomfortable opponents for Brighton rather than obliging ones. The 94th-minute winner in February 2026 was the most vivid expression of that quality, but the process was visible in every one of the four preceding fixtures. Progressive improvement across a rivalry, delivered through consistent tactical identity, is the kind of foundation that tends to sustain itself. A side that learns how to draw at the Amex eventually learns how to win there late.

The M23 derby may never attract the national attention that fixtures between the traditional top-six clubs command. But for the supporters who live it across every season, it carries a weight and an intensity that no neutral broadcast fully captures. Cats chase mice, dogs chase cats, and Palace do not like Brighton. With the rivalry now meaningfully balanced again, every upcoming meeting carries the promise of something worth watching closely.
