Arsenal Women will compete in only three competitions next season, raising questions about squad size and whether the club needs to register the maximum 25 players for both the Barclays Women’s Super League and the UEFA Women’s Champions League. The registration rules for the two competitions differ, with the WSL requiring eight homegrown players and UEFA requiring at least four club-trained players and four association-trained players for a full 25-player List A. Arsenal currently have 25 professional players under contract, following the departures of Laia Codina, Katie McCabe, Beth Mead, Victoria Pelova, Barbora Votikova, Naomi Williams, and Manuela Zinsberger. Young midfielder Laila Harbert is also expected to move to San Diego Wave, where she would work with Jonas Eidevall again. The women’s transfer window in England opened on 16 June and closes at 11pm UK time on 3 September. Midfielders like Mariona Caldentey, Kim Little, and Frida Maanum will be key to the team's success. If Arsenal complete reported signings, the squad would increase to 30 players, making it necessary to sign an experienced third goalkeeper or give 17-year-old academy goalkeeper Amy Liddiard a professional contract. Another centre-back would also be expected, either as a starter or as third or fourth choice. Renee Slegers suggested that she may not want a full 25-player senior squad, preferring a balanced team where everyone can contribute. The UEFA position is more straightforward, with Arsenal having more than the required club-trained players through Wubben-Moy, Williamson, Hinds, Reid, Little, Kelly, and Agyemang. Russo is also association-trained, helping the club meet UEFA’s overall quota of eight locally trained players. The squad size decision will be crucial in determining the team's success in the upcoming season. With key players like Chloe Kelly and Caitlin Foord, Arsenal Women are looking to make a strong impact in the 2026/27 season. The team's performance will depend on how well they balance their squad size and player selection. As the transfer window progresses, Arsenal Women will need to make key decisions about their squad size and player signings. The club's management will need to carefully consider the requirements of both the WSL and UEFA competitions. The women's transfer window in England will close on 3 September, giving Arsenal Women limited time to finalize their squad size and player selections.
