The crucial ESC slots available to Portsmouth ahead of summer transfer window - and why Championship clubs are concerned
Pompey are keen to utilise overseas markets to boost John Mousinho’s squad this summer, but certain rule will dictate how many players from abroad they can sign
The official opening of the 2026 summer transfer window is fast approaching and, fingers crossed, Pompey are advanced in any negotiations for their top targets.
A busy recruitment period is anticipated, with the Blues keen to establish a playing squad that can compete higher up the Championship table.
And once again, the Fratton Park recruitment team will look abroad for players who they hope than help take them to the next level.
It’s an approach with varying degrees of success that has seen Pompey sign the likes of Nicolas Schmid, Elias Sorenson, Kusini Yengi and Hayden Matthews in recent years.
Meanwhile, over the course of last season five players were recruited from outside the UK in order improve head coach John Mousinho’s options, including Adrian Segecic, Gustavo Caballero, Mark Kosznovszky, Luke Le Roux and Jojo Dia.
It’s a market the Blues feel gives them more bang for their buck. Although, the the £500,000 acquisition of Ebou Adams in January from Derby County will certainly contest that view.
However, strict rules are in place on the number of ‘overseas’ players EFL clubs can recruit.
Thankfully. it’s a subject matter Pompey are well versed on, having successfully navigated their way through Elite Significant Contribution (ESC) rules and Governing Body Endorsement (GBE) work permit thresholds on numerous occasions in recent times. The example of Adil Aouchiche comes to mind!
Speaking to The News last month, chief executive Andy Cullen admitted Championship clubs are nervously waiting to see if these Home Office rules change over the summer.
There’s a serious risk of that happening, with the result seeing many clubs - including Pompey - potentially having to reassess their recruitment plans.
But what are the current rules and have Pompey room to bring in more overseas players in the weeks ahead, having dipped their toe in that market twice as recently as January?
We’ve taken a look in the hope we can provide some clarity on a complicated subject. Here’s our understanding of based on Pompey’s current squad.
What are the current ESC/GBE rules?
ESC rules allow English clubs to sign overseas players who fail to meet the standard points threshold (15 points) for a GBE work permit.
The system provides specific work permit slots for elite players, with Championship clubs permitted to sign four players on ESC visas.
Two of these are guaranteed, and two are earned based on the percentage of minutes given to English Qualified Players (EQP).
To qualify, a players must prove they are at an elite level and will make a significant contribution to their prospective club.
This is typically met by having international youth caps, appearances in continental competitions, or significant domestic minutes in a high-tier league.
An ESC-registered player can retain their slot for a period of 12 months, after which their club must apply for a standard GBE.
The player will qualify automatically if they have played in at least 25-percent of their club's league matches and hit specific minute thresholds, or if they have accumulated enough points based on their recent playing time in England.
What players at Pompey currently have ESC status?
It’s our understanding that both Mark Kosznovszky and Luke Le Roux are the only two first-team players occupying the club's Elite Significant Contribution (ESC) slots.
Both players’ prior playing backgrounds did not generate enough points to meet the15-point GBE requirement for an automatic visa when they arrived last summer.
Le Roux was signed from IFK Värnamo in the Swedish Allsvenskan, a league the FA categorises as a Band 5 competition. And while the midfielder played regularly in Sweden, Band 5 leagues generate fewer automatic GBE points compared to the likes of the German Bundesliga (Band 1) or the Dutch Eredivisie (Band 2).
In additions, while Le Roux is a South African international, he had not played frequently enough for Bafana Bafana in competitive fixtures before moving to Fratton Park.
Kosznovszky was signed from MTK Budapest, who play in the Hungarian Nemzeti Bajnokság I. The Hungarian league is classified even lower by the FA, sitting as a Band 6 competition.
Despite featuring for Hungary's national youth teams, the midfielder lacked the consistent senior, competitive international appearances for a top-ranked FIFA nation required to automatically bridge that league point gap.
Like Nicolas Schmid, Adrian Segecic and Hayden Matthews, though, both Le Roux and Kosznovszky can transition from ESC to GBE status to free up slots.
When can a player transition from ESC to GBE status?
All ESC players can transition to full GBE status after 12 months.
In the case of Le Roux, his change in visa will be processed this summer, having established himself as a first-team option under Mousinho and featured in more than 25-percent of Pompey’s Championship fixtures. That, and his caps for South Africa, means he should meet the 15-point threshold to automatically shift to a GBE.
Kosznovszky's transition will likely be delayed due to the season-ending knee injury he suffered against Charlton in December.
As a consequence, Pompey cannot automatically clear his slot this summer. Instead, they will likely need to submit a medical exemption appeal to the FA, or wait for him to return to fitness, accumulate more competitive match-day minutes later in the year, and re-apply during the January 2027 transfer window.
Can a player be denied GBE status after being on an ESC visa for 12 months?
Yes, a player can be denied GBE status after their 12-month ESC period ends, which prevents them from legally playing competitive football in the UK.
The club cannot register the player for competitive match squads, often meaning the club must then immediately loan or transfer the player to an overseas league where they can legally work, allowing them to accumulate points to try again later.
Did January arrivals Jojo Dia or Gustavo Caballero have enough points to go straight to GBE status?
Yes they did.
Senegal defender Dia holds full GBE status at Fratton Park because he logged significant regular minutes in the Norwegian top flight with FK Haugesund throughout the 2025 season prior to his Pompey move. That playing time allowed him to easily surpass the FA’s standard 15-point threshold, despite the 22-year-old having no international caps for his country.
Paraguay forward Caballero, who spent the second half of last season on loan at the Blues, secured full GBE status due to a combination of high-profile appearances in South American continental tournaments (Copa Libertadores and the Copa Sudamericana) and elite league banding (the Brazilian top flight, which has a Band 3 ranking).
So how many ESC slots will Pompey have during the 2026 summer transfer window?
Given Kosznovszky’s injury, Pompey will likely have three ESC slots available during the summer transfer window, which opens on June 15,
Will the ESC rules change any time soon and for what reason?
The FA is likely to change ESC rules because the game-time given to English Qualified Players (EQPs) has plummeted below protectionist thresholds.
When the relaxed visa framework was introduced, it served as a strict compromise - clubs gained access to untapped global markets only if they protected the developmental pathway for domestic talent.
However, a ‘nuclear option’ clause dictates that if cumulative EQP minutes fall to 25-percent or below in a season, the FA can legally suspend the system.
With Premier League clubs heavily relying on overseas squads, English minutes have breached this floor, forcing the FA’s hand.
In addition, the built-in incentive system failed - wealthy teams bypassed the restrictive ESC slots entirely by purchasing premium international talent who cleared standard work visas automatically. While Premier League spending caused this decline, Championship clubs face the brunt of the collateral damage.
Because the FA intends to penalise the entire pyramid for failing domestic development quotas, they are threatening to shrink total club allocations from four slots down to two.
