Barcelona has vowed to "take every possible action" to have the decision to exclude their women's squad from the Copa de la Reina overturned.

For the past three years, the Catalans have won both the Spanish league and cup, however it has since been revealed that they fielded an ineligible player in their 9-0 victory over Osasuna in the last 16 of the current cup campaign.

On January 10, Osasuna was outmatched, but due to Barcelona striker Geyse playing and scoring although she was supposed to be serving a suspension, the team was proclaimed the victor on a technicality.

Brazilian Geyse was dismissed from her prior competition game while representing Madrid CFF in a quarterfinal matchup against eventual champions Sporting Huelva.

Barcelona believe there are grounds for the ruling to be successfully challenged, with ESPN reporting the club are adamant Geyse was not listed on pre-match lists of disciplinary disqualifications issued by cup organisers the Royal Spanish Football Federation (RFEF).

In a statement issued after Tuesday's expulsion, the Camp Nou giants said: "FC Barcelona announces that the club is to continue to fight for the women's team's rights after they were sanctioned by the competition committee for fielding an ineligible line-up, with an appeal to be presented in due course.

"Should the sanction not be revoked on appeal, FC Barcelona will take every possible action, as it is considered that the line-up ended up being deemed ineligible due to technicalities in this case."

Barcelona, who beat Real Sociedad 3-0 in the Supercopa on Sunday, appear well on course to claim the Spanish league title for a fourth season in a row after winning 14 consecutive games in the competition since the start of the season.

Barcelona have also been fined €1,001 by the RFEF over the ineligibility episode, while Sevilla have been thrown out of this season's cup, too, after Nagore Calderon played in a 1-0 win against Villarreal, when she too had a suspension hanging over her from last season.

Sevilla said they presented arguments against such a punishment but will not appeal any further.
