The attacking midfielder is enjoying arguably the finest season of her City career to date and the 31-year-old was at her dynamic best across December, helping us end the year on a high.
Coombs struck a stunning long-range effort to help Gareth Taylor’s side overcome Brighton 3-1 at the Academy Stadium.
And she was then on target again in our record-breaking Etihad derby against Manchester United, her second half strike securing a 1-1 draw in front of a record attendance of 44,259.
It was her fourth goal of the season to date with Coombs also weighing in with three assists to mark the most productive return of her career yet.
Coombs faces competition for the award from Ona Batlle and Leah Galton of Manchester United, Chelsea duo Fran Kirby and Guro Reiten along with Arsenal’s Vivianne Miedema and Everton's Emily Ramsey.
