The Women's Super League's summer transfer window has now closed ahead of the 2026-27 season. Data analysis suggests Arsenal has made the biggest improvement to their squad, with new players valued at a combined €3.9m.
London City Lionesses also made significant gains, with new talent valued at €3.5m. Their new two-time Ballon d’Or winner, Alexia Putellas, is valued at €1.15m, exceeding the entire Charlton squad's value.
West Ham saw substantial changes, losing players who contributed 6,322 minutes in the previous WSL season, representing 29% of their total playing time. Their new players' combined market value of €1.02m surpasses the €0.96m value of their remaining players from last season.
The WSL's approach to the transfer window has been highlighted for its organisation, with the window closing before the new campaign began. This contrasts with the Premier League, where a significant portion of deals and spending occurred after the 2026-27 season had already started.
