The defender, 21, graduated in December after spending the past four years playing and studying in the USA, where after a season at Penn State she moved to the University of South Carolina.

Before moving to America, Fisk had a brief spell at Millwall.

"I am so excited to join West Ham. Once I came and had a look at the set-up, I knew straight away this was where I wanted to come and play," said Fisk.

West Ham will be at home to Everton when the Women's Super League resumes on Sunday 5 January.
