The 23-year-old, who can play as a winger or through the middle, has arrived from St John's University in New York.

She made 20 appearances for Everton prior to her four-year spell in the United States.

Whipp, who has represented England from under-15 level through to under-23, is reunited with her former Everton team-mate Claudia Walker at Birmingham.

Meanwhile, forward Emma Follis has left Blues to join city rivals Aston Villa Ladies for an undisclosed fee.
