Tebas announced last Thursday that a 15-year agreement had been reached with Relevent, the company behind the ICC, to stage one La Liga game a season outside of Spain.
The league president wants the game to feature either Real Madrid or Barcelona, but 'AS' are reporting that this would need the blessing of the FA.
The governing body wasn't consulted before the decision was announced, despite being the body that oversees all football in Spain, and so their approval is key.
It also must be said that this plan will be hard to carry out for various other reasons: the clubs are not obliged to play and could turn it down and the it still has to be rubber stamped by the assembly (which will next meet in September). Then you have to add on the potential loss of a game to the fans and clubs and the relatively small number of dates available.
Furthermore, Real Madrid are particularly put out by the agreement, with the announcement being made without any knowledge by 'Los Blancos' board. Barcelona, the other big team involved, apparently have a rosier outlook.
La Liga will need to ask for permisssion from the Government to play an official game in another country. If that gets the green light, then the RFEF comes next.
After, it would have to get approval from all the football bodies involved, namely UEFA, the US Soccer Federation, CONCACAF and FIFA.
