Manager Vera Pauw has confirmed a 30-player squad for what is their penultimate game in Group I away to Ukraine on October 23 when they know that a point would guarantee a play-off slot for next summer's Euro 2022.
The squad will be trimmed within a fortnight, although the nine players featured from the Women's National League will hearten a minority in the domestic game who have quibbled at the Dutch coach's non-attendance at games.
Pauw was forced to defend herself last month, stating that while she does not attend matches due to Covid-19 difficulties, she does watch every match and her assistant Eileen Gleeson also attends most league encounters.
While a point can secure a play-off, Ireland, still buoyant despite their first defeat in the group to runaway leaders Germany last time out, will be keen to match Pauw's debut victory in Tallaght, as there are three automatic berths available for the best-placed runners-up.
Group leaders Germany will visit Dublin on December 1 to conclude their qualification campaign. Ireland will hope by then theirs is still ongoing.
Ukraine trail the Irish by seven points but have a game in hand and they were fiendishly tricky in the reverse fixture last year.
Ireland play Ukraine in the Obolon Arena in Kiev on Friday, October 23 (KO 4.30pm Irish time).
