Who could be on the move?

After a busy summer window, it is expected to be much quieter in January but clubs are keen to add more quality - particularly in attack.

Swedish forward Stina Blackstenius was on Manchester United's wish list in the summer and is expected to join in January from BK Hacken when her contract expires.

United might have to fight off interest from the United States for their England striker Alessia Russo. Former manager Casey Stoney, now at San Diego Wave, could try to take her. She has been unable to sign a player from United for six months under the terms of her departure, but would have to pay a fee for Russo, who remains under contract.

Manchester City's Janine Beckie is attracting interest from the USA, while Finland international and Real Sociedad forward Sanni Maija Franssi is a target for a few WSL clubs.

Reading, Birmingham City and Leicester City are looking at young English midfielder Isabella Sibley, who has returned from a spell in the United States.

Norwegian midfielder Tuva Hansen and Denmark midfielder Emma Snerle will also move to England, with Reading a potential destination, while there are a few WSL clubs looking at Slovenian centre-back Lana Golob.

USA midfielder Kristie Mewis trained with Tottenham for a week in December before she was drafted by Gotham FC. She was said to be open to a move to London but Spurs would need to pay a high fee.

Coventry United were placed in voluntary liquidation, meaning their players are available, and there is interest in striker Katie Wilkinson from a few WSL clubs as well as the Championship.

Wilkinson played under Aston Villa boss Carla Ward at Sheffield United and could reunite with her in the Midlands, while Coventry United team-mate Rio Hardy has trained at Villa for a few days.

Arsenal and Scotland defender Lisa Evans could make her loan move to West Ham permanent.

Villa defender Natalie Haigh is among those who could be open to a loan move in pursuit of regular game time, while young Everton midfielder Grace Clinton could attract interest in a loan deal.

Leicester City are chasing an experienced goalkeeper with Chelsea's Carly Telford and Manchester City's Karen Bardsley among those being linked with a move. Telford was also the subject of enquiries from several clubs in the summer.

Sweden's BK Hacken goalkeeper Jennifer Falk has reportedly received interest from a WSL club.

Striker Jeon Ga-eul has left Reading and will join South Korean side Sejong Sportstoto in the WK League.

What do clubs need?

West Ham, Leicester City, Birmingham City and Reading are all hoping to be active in the transfer window

West Ham are expected to be active in the transfer window and will be given funds but only if they get their preferred targets. They are said to be shopping for a forward and are willing to look around Europe.

Reading's priority was to bring in a central midfielder and a centre-back - they have already announced the signing of Denmark midfielder Sanne Troelsgaard.

Aston Villa have several targets as they try to bolster their attacking options. Players will also leave on loan in order to gain game time, including several talented youngsters.

To keep up their pursuit of Champions League football, Tottenham are expected to strengthen - and will have the money to do so.

Brighton may only strengthen in one or two positions but Everton, Birmingham City and Leicester City are expected to be busy in the market under new management.

Leicester City are said to be looking into at least one Serbia international, as well as an experienced goalkeeper. They could also see players leave on loan.

Arsenal may look to bring in a replacement for injured centre-back Leah Williamson, while Tobin Heath's absence - plus the continued interest from other clubs in their main striker Vivianne Miedema - means they could sign another forward too.

Chelsea are not expected to be busy but could strengthen in one or two areas.

Meanwhile, Manchester United are expected to make a few signings, particularly in attack, while rivals Manchester City need cover for injured players and could be active.
