Naomi Hartley joins Sheffield United on a permanent basis after spending the second half of last season on loan from Manchester United.
A committed centre-back, the 18-year-old has already forged a reputation as a talented defender after spells with Liverpool and the newly-launched Man United team.
After leaving Liverpool last summer, Hartley followed several of her team mates to Manchester to work under Casey Stoney, but lack of game time saw her join the Blades in January where she became an ever-present member of the starting eleven during a positive second half of the season.
Now with the Blades for her first full season of first team football, Hartley has also represented England all the way up to Under-18 level where she recently played all three games in a camp at St. George's Park.
