The Women’s Super League (WSL) transfer deadline day on September 4, 2025, marked an exciting and record-breaking conclusion to a dynamic summer transfer window. Clubs across the league finalized key signings and departures ahead of the new WSL season, which kicks off immediately after the transfer window closes.
Transfer Deadline Timing and Rules
The WSL summer transfer window officially closed at 11 p.m. BST on September 4, 2025, just one day before the season’s opening fixtures. Clubs had until that time to register new domestic transfers, with midnight allowed for international transfers. Each team must register a squad of up to 25 senior players with at least eight homegrown players, and may carry up to six long-term loans.
Record-Breaking Transfers and Highlights
The headline transfer of the window was Olivia Smith’s historic £1 million move from Liverpool to Arsenal, making her the first woman player to hit the £1 million transfer fee mark in WSL history and briefly setting a world record. Other top teams like Chelsea and Manchester City also bolstered their squads with high-profile signings and strategic recruits, aiming to defend their status among league leaders and contend in European competition.
Newly promoted London City Lionesses made significant moves to bring experience and talent, including signing Dutch midfielder Daniëlle van de Donk from Lyon and England’s Katie Zelem, preparing for their maiden WSL season. Tottenham Hotspur made minimal signings, with Japan’s Toko Koga from Feyenoord being their notable addition.
Impact on Clubs and Season Outlook
The deadline day activity reflected the increasing professionalism and financial muscle of the women’s game, with clubs balancing marquee signings and squad depth. Chelsea brought in four permanent recruits, while London City Lionesses revamped their squad with 14 new players, signaling ambitions to establish themselves in the top division. The transfer window closure just before the season start heightened the drama and anticipation for fans and analysts alike.
