Players have reported for duty with Spain's women's national team with the threat of a fine or a domestic ban looming over them if they don't.
The six Madrid-based players arrived at a hotel in the Spanish capital on Tuesday before departing for Valencia, where they were later joined by the rest of the squad -- including those from Barcelona -- to prepare for UEFA Nations League games against Sweden and Switzerland.
NJ/NY Gotham FC forward Esther Gonzalez will not travel from the United States after suffering an injury and she will be replaced by Sevilla's Cristina Martín-Prieto, the national team announced on Tuesday.
Twenty of the 23 players called up by new Spain head coach Montse Tome on Monday had released a statement on Friday saying they were unwilling to play for the national team until changes were carried out by the Royal Spanish Football Federation [RFEF].
The players, many of whom helped La Roja win the World Cup last month, said they were surprised by their call-up on Monday after they had made clear their decision not to play for Spain until their demands for change were met.
However, according to Spanish sports law, athletes are required to answer the call of their national team unless there are circumstances that impede them from playing, such as an injury.
Should they refuse the call, the players face sanctions including fines of up to €30,000 ($32,000) and the suspension of their federation licence for two to 15 years.
Victor Francos, the president of the supreme council for sports in the country [CSD], said he hopes it does not come to that and plans to act as a mediator between the players and the RFEF.
"If the players don't show up, the government will do what it has to do, which is to apply the law," Francos said. "Unfortunately, the law is the law, but I still hope that there can be a solution. I am going to talk with the players. I am going to try."
Upon his arrival, Francos added: "We want to listen to the players. What happened on Monday is unacceptable. That has been transmitted to the RFEF. I felt my obligation was to be here alongside the players and to listen to them and look for solutions."
Miquel Iceta, the minister of culture and sport, said he cannot imagine the players being sanctioned and called on the RFEF to make the necessary changes.
"The RFEF does not have the right to deprive Spain of the women's national team, especially after they have won the World Cup," Iceta said.
"We call on the RFEF to enact structural changes to ensure the federation is a safe, competitive, professional space.
"I can't even imagine [sanctions.] We are going to find a solution. What cannot happen is that injustices continue to be committed which harm the players who have given the best of themselves and won a World Cup for the first time in history.
"We have to get back on track and live up to what society demands and to what the players have earned."
Spain's players first pushed for change at the RFEF last September when 15 players made themselves unavailable for selection until certain improvements were met.
Three of the 15 eventually returned for the World Cup, which ended with Spain beating England in the final in Sydney, but federation president Luis Rubiales' conduct after that game has re-opened the dispute.
Rubiales, who has since stepped down following an outcry, is facing criminal charges for an unsolicited kiss on Jenni Hermoso, while he was also condemned for grabbing his crotch, hugging and kissing some players and throwing another over his shoulders.
When he initially refused to resign, 81 current and retired Spain internationals said they would not play for the national team again under Rubiales' leadership.
Following his resignation, plus the dismissal of coach Jorge Vilda, 39 players, including 21 members of the World Cup winning squad, announced last Friday they were still seeking further changes.
In a statement published on social media, they asked for a restructuring of women's football within the RFEF as well as changes to the president's cabinet, the media and communications department and the integrity department.
Of the 39 signatories, 20 were called up by Tome on Monday. Athenea del Castillo, who was in the World Cup squad, did not sign Friday's letter and said she was ready to play for the national team.
María Méndez and Rosa Márquez are the other two players whose names don't appear, although they have not previously been regulars with the national team.
Hermoso has not been called up and on Monday she hit back at Tome's suggestion that she had been left out to "protect" her after she pressed charges against Rubiales for sexual assault.
"Protect me from what? And from whom?" Hermoso said in a statement.
Mapi Leon, who gave up the World Cup because of the situation at the RFEF and has now been forced to come back, also questioned whether it was a safe environment for the players.
"Do we feel we have support? Yes, but maybe not from who we should have it from," she said. We have to talk long and hard about if we are coming to a safe place or not when we have been forced to come.
"This is the question we all have to ask: What do we have to be protected from? I think my position has been very clear. At no moment have I changed my opinion. I have given up a lot. Me and Patri [Guijarro], for example, both have to now be called into the squad without being asked. We have been forced to come. But if they want to sanction us, then we have to come."
Spain face Sweden in Gothenburg on Friday and then host Switzerland in Cordoba on Tuesday, Sept. 26. Both games are in the Nations League, which also serves as the qualification pathway for next summer's Olympics.
