The 2014 FIFA World Cup in Brazil generated various controversies, including demonstrations, some of which took place even before the tournament started. Most centred on officiating, with referees coming under criticism for their performances. Furthermore, there were various issues with safety, including eight deaths of workers and a fire during construction, breaches into stadiums, an unstable makeshift staircase at the Maracanã Stadium, a monorail collapse, and the collapse of an unfinished overpass in Belo Horizonte. The most notable disciplinary case was that of Uruguayan striker Luis Suárez, who was disciplined after biting an Italian player, defender Giorgio Chiellini, during a game.
