There are not many specialists in that position :
Katie Chapman is a world class player and has everything you want in that position. She does everything right in term of defensive work and also as a platform to starts the attacks.
Anita Asante is a very gifted player who reads the game well and can also help in the attacking build up as her distribution on short passing is excellent. She also the ability to turn and run under pressure and therefore create space and breach the opposition defensive block.
Fara Williams has not been at her best recently but she the women’s equivalent of Andrea Pirlo. She is technical has a great vision and a phenomenal passing range with both foot, she can switch play on demand.
Jessica Fishlock has recently played in that position for Wales and has been excellent with her energy and fighting spirit.
Abbie Prosser and Rebecca Anderson are two specialist but clearly lack experience and should be developped to be candidates in a couple of seasons.
