Alone against everybody

This August the Spanish football federation signed an agreement with Relevent Sports agency on 15 years. In the deal, as well is written that one match from Primera division have to be played in United States of America each season, starting with Girona and Barcelona which is scheduled on 27 January 2019. Against this controversial contract are most players, coaches, and even some unions in Spain.
For the first time in many years (or decades) FIFA is doing something right by saying that this cannot happen after all. On the last Friday in October, its president explained that every championship games must be played within the borders of each country. However, the other party thinks otherwise. Spokesman of LaLiga have said that is ready to go to court defending the signed document, if the whole thing becomes officially forbidden.
