The 2004–05 FC Barcelona Femení season was the club's ninth in the top flight of Spanish football, though their first in the top flight after it was restructured into the Superliga in 2001. Having won the second division every season, Barcelona earned promotion through play-offs for the first time in 2004.
Summary.
Barcelona promoted defender Melanie Serrano from the B team and signed top Spanish goalscorer Adriana Martín, among other incorporations, ahead of their debut season in the Superliga. They began the campaign badly, with only one win in the first half of the season. Towards the end of January 2005 they were bottom of the league with only seven points, before signing Mexican star goalscorer Maribel Domínguez (who had been playing summer seasons in the United States) on 25 January 2005. Known as Marigol, she had been originally planning to move to the Mexican men's league in the transfer window, but was prevented from doing so by FIFA and went to the struggling Barcelona instead. Her signing was considered the league's biggest signing since Milene Domingues "Ronaldinha" gave a profile boost to Rayo Vallecano in 2002. Domínguez said at the time that part of her motivation for joining Barcelona was to open doors for more Mexicans to play in Spain, considered a top football nation, with the Superliga being highly restrictive on foreign players at the time. Domínguez debuted in the team's next game, scoring a hat-trick in their 5–0 victory. After a triumphant start, with five goals in her first three games, Domínguez then travelled back to Mexico to serve as an ambassador for FC Barcelona. She returned to Spain ahead of the team's match against Pozuelo.
The team ultimately finished ninth in the Superliga, with Domínguez named captain by the end of the season. Her presence had given the team a boost, and interest from both fans and the media grew massively in the back half of the season; this led to matches being returned to the Mini Estadi (after demotion to the stadium's auxiliary pitches) and for the team to play a three-match tour in Mexico at the end of the season.
