After a shakeup of the WSL Tier 1 and Tier 2 structure, the January transfer window could be a busy affair with many clubs already making movements in the market.

Manchester City have already announced two new players to add depth to their injury hit squad. They have lined up the Danish forward Nadia Nadir from the Portland Thorns and midfielder Julia Spetsmark from KIF Orebro.

Chelsea have also dipped again in the Scandinavian market with defender Jonna Anderson signed from Linkoping.

The Londoners also brought back former defender Anita Asante, a close friend of Eniola Aluko, who also backed Eni Aluko her racism fight against Mark Sampson and the FA.

Arsenal have welcomed back Katie McCabe from Glasgow City after her loan. On the departure side, Jodie Taylor has left Arsenal for W-League side Melbourne City, before returning to the NWSL with Seattle Reign.

Reading announced Mandy Van Den Berg is returning home, Watford Ladies lost Kylie McCarthy to Lewes Ladies and Merrick Will joined London Bees. Many others look on their way out following withdrawal of many clubs from the WSL.

As for expected transfers, the teams wearing red and blue from Merseyside and the South East seem to be busy working on many deals.

A forward is expected to leave London to move up North, to replace another one who will make her way to the South East of England. She is now a free agent and will move without a transfer fee.

West Ham, currently in the third Tier in the WPL Southern, will bid for a Tier 1 place and are lining up a few WSL players. They are waiting for the window to open to sign a striker, and they might get a new manager in place soon too.

If the Londoners are confirmed in Tier 1 in June, they will need to sign up at least 15 players to be competitive at the top level.
