Footballers in Spain have not ruled out strike action over a plan to stage a top-flight league match in the United States, says the players' union.
Real Madrid captain Sergio Ramos and Barcelona vice-captain Sergio Busquets were among the high-profile players to attend a meeting on Wednesday to discuss their "concern" over the issue.
La Liga agreed a 15-year deal with US media company Relevent on Friday.
The players' union - the AFE - says its members were not consulted by La Liga.
Players from all of the La Liga sides met in Madrid on Wednesday to discuss the issue with AFE president David Aganzo.
Among those in attendance were Ramos and Real Madrid team-mate Nacho, Barcelona duo Busquets and Sergi Roberto, Leo Baptistao from Espanyol, Bruno from Villarreal, and Atletico Madrid players Koke and Juanfran.
Aganzo said: "The problem is the lack of common sense, a schedule where only the export of soccer benefits - nobody counts on the fans.
"We need to fix it with the bosses. The captains are outraged, they're against it, they are unanimous.
"It does not make sense. We are talking about an agreement that has a validity of 15 years without consulting the players."
On the possibility of strike action, he added: "We will try not to reach that extreme but we are willing to go to the end if necessary."
Aganzo said the players would meet again in September.
Asked last week when the US-based match would take place, and whether it would be a regular fixture, La Liga told BBC Sport it "cannot confirm the teams, match, date or season".
The AFE said players "do not understand the unilateral decisions", adding: "La Liga is distancing the fans of the players, something that harms the show and the essence of football."

They shouldn't go play games abroad it makes absolutely no sense they are turning football into business real fast which is not good no players were consulted that is kinda insulting to players and they do this for money not for love of the game if Americans like football that much then they should invest more in the sport instead of trying to buy their way to watch top flight football when I first heard of it I despised the idea it will be unnecessary stress for team having to fly about for just a game they are used to playing on local soil big NO

I agree with the players. I don’t understand why some people will go any lengths to destroy the beautiful game of football. Shame unto the la liga league board. So does it mean there will be no home or away games for the teams? This is absolutely nonsense. The fans are behind them solidly. The lives of the players will be ruined. Different time zones and not to mention the risk involved in traveling.

I was always skeptical abt this US deal when it broke out. Therefore i must say: Great! A very great & honourable gesture by respectful & dedicated professionals who have stood up & said NO to a bunch of money-hungry league executives who are tryin to make fortunes off the hardwork of professional footballers Its a shame

These players are spitting absolute rubbish. Firstly They earn thousands of dollars weekly to play football. And The club decides to find other avenues to make more money isn’t that reasonable? Secondly, they have a job to do. That’s what they are paid to do, to play football for their respective clubs and not moan about where they are playing the football. Thirdly, the fans in USA will also have a privilege of seeing their clubs/players play live without traveling Spain. It’s a win-win. This is just my opinion and how I see the issue.
