Charles has re-invented herself as a left-back this season under the guidance of Hayes. She has been so impressive in her new role that Sarina Wiegamn, the England women's team boss, has also deployed her as a full-back in the international arena. She surges forward at every given opportunity since she used to play in attack, as a winger or as a No.10, and her accurate acrosses have been an asset to Hayes.
