Hanane Ait El Haj and Peace Efih earned their debuts, while Rachel Nachula made her Spanish Reto Iberdrola scoring-debut for Zaragoza as her effort forced a 1-1 draw against Osasuna on Sunday.
Morocco's Ait El Haj, Nigeria's Efih and Zambia's Nachula joined the Spanish outfit this summer and they were handed starting debuts by coach Nacho Bracero in their side's draw with the visitors.
The two teams created several chances in the opening 45 minutes but could not convert any as they head into the half time break with a stalemate at the Enrique Porta de Villanueva.
