Nineteen-year-old winger Lisa Baum scored on her Arsenal debut to secure a 1-0 win at Brighton, breaking the deadlock in the 10th minute with a shot into the top left corner. The new-look Arsenal side, featuring new signings Misa, Georgia Stanway and Ona Battle, created chances but failed to double their lead, with Alessia Russo and Stina Blackstenius squandering close-range opportunities. Arturo Ruiz praised his side's spirited defensive performance despite the loss.

Tottenham began their WSL campaign with a convincing 3-1 victory over West Ham. Debutant Kirsty Hanson was the star, scoring twice, including a curling effort from outside the 18-yard box. Signe Gaupset opened the scoring with a smart finish and assisted Hanson's first goal. Despite West Ham's 10 summer signings, including four starters, they struggled to gel as Spurs controlled the tempo. Viviane Asseyi grabbed a stoppage-time consolation for the visitors.
