Arsenal must finalise their UEFA competition squad by an 11pm deadline on Wednesday, September 2. The club is one of nine Premier League sides with just 48 hours after the transfer window to register their players for European phases, as reported by the Daily Mirror.
Mikel Arteta's side, currently 2nd in the Premier League with six points from two wins, have scored four goals without conceding. Their next challenge is a home match against Chelsea on September 6, a fixture detailed on our fixtures page.
What are the UEFA squad registration rules?
Each club can name a maximum of 25 players for UEFA competitions, and this list must include at least two goalkeepers. A core requirement is the inclusion of eight 'locally trained players'. These are defined as players registered with any club in the same national association for three seasons, or 36 months, between the ages of 15 and 21.
Within that group of eight, at least four must be 'club-trained players'. This means they were on Arsenal's books for three seasons or 36 months during that same age period. No more than half of the eight locally trained players can be 'association-trained', meaning they were developed at another English club. This structure forces teams to balance new signings with long-term academy development.
Which other Premier League clubs are affected?
The deadline applies to all English clubs participating in UEFA tournaments. Alongside Arsenal, the list includes Aston Villa, Liverpool, Manchester City, Manchester United, Bournemouth, Crystal Palace, Sunderland and Brighton & Hove Albion. Manchester City, for instance, must formally register new arrivals Enzo Fernandez and Iliman Ndiaye.
Crystal Palace announced four deadline-day signings: Dario Osorio from Midtjylland, Quinten Timber from Marseille, Ben Chilwell and Honest Ahanor. Sunderland secured Malick Fofana from Lyon after a prolonged saga, plus Juan Riquelme Angulo and Kevin Danso from Tottenham Hotspur.
What is the situation with Aston Villa?
Aston Villa's summer activity adds a layer of complexity. The club was fined £19million by UEFA in 2025 for a major breach of squad cost rules. As a result, they cannot register new players unless their list balance is positive. This means the cost of new signings must be lower than the savings generated from player sales.
The club has been active, spending around £250million this summer while recouping over £300million in sales. Their deadline-day business brought in Ibrahim Mbaye and Taylor Harwood-Bellis. Other summer arrivals include Johan Manzambi, Joao Gomes, Leon Goretzka, Matteo Ruggeri, Nicolas Jackson and Zion Suzuki. Their compliance with UEFA's financial regulations will be tested as they submit their squad.
How does this impact Arsenal's planning?
For Arsenal, the immediate task is to formally submit a compliant 25-man list to UEFA by Wednesday night. The process involves confirming which players meet the strict homegrown criteria. This administrative step is separate from domestic Premier League registration but is essential for their European campaign.
The club's strong start to the season, with a perfect record and a +4 goal difference, provides a solid platform. You can track their league position on our standings page. Arteta and his staff will have planned for this deadline throughout the window, ensuring their final squad aligns with both sporting ambitions and regulatory demands. The confirmed squad will be available for review on our squad page once submitted.
Arsenal's focus now shifts to preparing for the visit of Chelsea this weekend, following the submission of their UEFA list.
