Having worked her way up the ranks at Everton, Levell made her debut in the 2015 season, going on to make 16 appearances that campaign.
The arrival of Alex Brooks on loan from Manchester City increased competition between the sticks but Levell continued to be included in the matchday squad throughout 2016 and ended the campaign as number one.
Levell retained that spot for the 2017 Spring Series, playing every game and conceding just seven goals in nine matches as the Toffees lifted the trophy.
Lizzie Durack's arrival prior to the start of the 2017-18 WSL 1 campaign saw Levell new competition, but she featured as the Toffees reached the Continental Cup quarter-finals and the semi-final of the FA Women's Cup, again finishing the campaign as Everton's first-choice stopper.
Levell was a near ever present for the Blues in 2019-20, too, making 22 appearances as the Club embarked on a new era under Scottish manager Wille Kirk.
