Sunday's game is set to be a massive occasion in the WSL season as only two points separate the two sides in the table, with United third on 12 points and City sixth on 10 points.
History also awaits both sets of players, as this is the first time the fixture has been held at the Theatre of Dreams.
Seats for Sunday's 16:30 GMT kick-off are priced at £15 for adults and £7.50 for fans aged 16 or over 65. You can secure your tickets here.
