Real Madrid have opposed staging a Spanish league game between Barcelona and Girona in the United States.
La Liga asked the Spanish Football Federation (RFEF) for permission to hold the match in Miami on 26 January.
In a letter to the RFEF Real said it was “fundamental” teams play “home and away at each other’s stadium” for “the integrity and equality” of La Liga.
The RFEF president Luis Rubiales has spoken out against the game, as has the Spanish players’ union (AFE).
European governing body Uefa, the US Soccer Federation and Concacaf, which governs the game in north and central America and the Caribbean region also need to give their permission for the game to happen.
The proposed ‘home’ match for Girona, a Catalan town situated around 60 miles north of Barcelona, would take place at Miami’s Hard Rock Stadium on 26 January at 19:45 GMT.
