Hollie Barker joined from Rotherham United Ladies in 2017 and made the step up when the Blades moved into the FA Women's Championship last season.
Hollie made an impression in her early days at the club, scooping the Players' Player trophy at the end of the 2017/18 season and she continued to hold down a regular role in the side last season.
Sheffield-local Hollie was one of just four players retained last summer. A hard-working full-back, Barker has also played for Huddersfield Town Ladies before swapping Rotherham for Sheffield.
Hollie earns a living as a personal trainer for her company HB Reform.
