Barcelona president Josep Maria Bartomeu has kept up the pressure for this year's Copa del Rey final between his club and Athletic Bilbao to be played at the biggest possible stadium -- meaning Real Madrid's Estadio Santiago Bernabeu.
As Spain does not have a national stadium, the final is hosted each year by a different club, and generally played in the biggest neutral venue which is available.
Barca and Athletic figures have both indicated that the 81,000-seater Bernabeu would be ideal as it would allow the largest number of fans to attend this year's decider on Saturday May 30.
However, Madrid president Florentino Perez, and many Blancos fans and pundits, would prefer not to have thousands of Catalan and Basque fans inside the Bernabeu in what is Spain's end-of-season showpiece occasion.
The current front runner is Valencia's Mestalla, with the Estadio de La Cartuja olympic stadium in Sevilla another option, although both grounds are smaller than the Bernabeu and not as accessible for travelling fans of either team.
The Spanish federation will have the final say on where the game is played, and Bartomeu was quoted in Marca as saying that a decision would soon be made by RFEF president Angel Maria Villar.
"There will be a meeting in the coming days, and Villar is the person who decides where it will be played," Bartomeu said. "I have always said I want a ground with a big capacity, and we are in constant contact with the Spanish federation."
A similar situation arose when the teams met in the 2012 final. Madrid then argued that renovation work at the stadium, including new toilets, meant the Bernabeu was unavailable.
That year's final was played at Atletico Madrid's Estadio Vicente Calderon, which is unavailable this year due to a concert appearance by AC/DC.
The 2012 decider is remembered in some circles for Spain's then-king Juan Carlos and the national anthem being loudly whistled by fans of both finalists.
Such behaviour was heavily criticised this week by veteran Partido Popular politician and candidate to be the next mayor of Madrid Esperanza Aguirre, who wrote in El Mundo that teams who showed such "hate" should not take part in the Copa at all.
