Legall joined the Swans at the beginning of the 2022-23 season, making her debut for the club against AC PAOK in Champions League qualifiers.

The forward joined from Cheltenham Town, having previously played for Cyncoed, Cardiff City Ladies and Cardiff City Women, and netted four goals in her first season with the Swans, claiming the award for best newcomer.

The 26-year-old took a break from football in 2024 to give birth to her daughter Mari, but returned to training in the latter stages of 2025 and officially re-signed with the Swans in December.
