In the summer of 2005 she moved from Sabadell, which would disappear just months later, to RCD Espanyol. In her first season in the white and blues she won both the League and Cup. This stage ended abruptly in May 2009 as she uploaded to her Facebook account photos which showed her supporting Espanyol's rival FC Barcelona at the 2008-09 Copa del Rey final in Valencia. Rubio was dismissed from the team for the remainder of the season and her contract was not renewed.
