Ecuador's football federation has filed a complaint with World Cup organizers over noisy Mexican fans outside their team hotel before their last-32 match against co-hosts Mexico.
Local media reported that around 1,000 Mexico supporters staged a noisy 'serenade' in Mexico City on Monday, using noisemakers, pans, and buckets to sing the Mexican folk song 'Cielito Lindo' before police moved them back.
Ecuador's federation stated, 'This conduct is far removed from the principles of fair play, equality, and unity that a football World Cup should represent.' They added that they would 'always respond on the pitch.'
