Ecuador, Mexico fans, FIFA and World Cup organisers.
Before Ecuador’s round-of-32 match against Mexico in Mexico City.
Ecuador have complained to World Cup organisers after local fans staged a noisy serenade outside their team hotel. Reports said around 1,000 Mexico supporters used music, pans and noisemakers before police moved them back.
Ecuador’s federation called the behaviour contrary to fair play, equality and World Cup unity, while saying the team would respond on the pitch. FIFA was contacted for comment before the knockout match at Mexico City Stadium.
