Walti has made 129 appearances for the Gunners, scoring two goals, and helped them win the FA Women's League Cup last season in addition to the Women's Super League championship in her first season in 2018. However, behind her, there are others like Victoria Pelova, Kathrine Kuhl and Kyra Cooney-Cross, all of whom are seen as the future generation, which could lead to Walti's decision to move away from the Gunners.
