The Spanish football federation has reportedly rejected La Liga's request for Barcelona's game against Girona to be played in Miami.
'A letter was sent to La Liga this morning in which it denies the game request because it does not comply with the international rules', said a source from the federation told Reuters.
According to FIFA's statutes, any domestic competition played outside the league's usual home must be approved by the home federation, UEFA, the federation where the game is taking place and the regional confederation - in this case, the United States Soccer Federation and CONCACAF.
FIFA president Gianni Infantino revealed in an interview that he is not keen on the idea.
'I think I would prefer to see a great MLS game in the US rather than La Liga being in the US,' he said.
'In football, the general principle is that you play a home match at home, and not in a foreign country.'
