Highest margin of defeat by the host nation in a football (soccer) FIFA World Cup match

The highest margin of defeat suffered by the hosts in a FIFA World Cup match is by 6 goals when Brazil lost 1-7 to Germany in the Semi-Final match at the Mineirão, Belo Horizonte, Brazil on 8 July 2014. Brazil's heavy defeat in Belo Horizonte has been dubbed the Mineiraço as they became only the 2nd host nation behind Mexico to host the World Cup twice and not win it on home soil. The previous record for the heaviest defeat by a host nation was just 3 goals - South Africa lost 3-0 to Uruguay in Pretoria in 2010, Mexico lost 4-1 to Italy in Toluca in 1970 and Sweden lost 5-2 to Brazil in Solna.
