The 1970 World Cup was the first one in 12 years, and it was also the first time in 20 years that Sweden had "qualified" for a World Cup.  (Sweden hosted the 1958 FIFA World Cup, and hence did not need to qualify.)  Sweden did not qualify for the World Cups in 1954, 1962 and 1966).

2018 and 2022 FIFA World Cup bids: The bidding process for the 2018 and 2022 FIFA World Cups was the process by which the Fédération Internationale de Football Association (FIFA) selected locations for the 2018 and 2022 FIFA World Cups.  The process began officially in March 2009; eleven bids from thirteen countries were received, including one which was withdrawn and one that was rejected before FIFA's executive committee voted in November 2010.  Two of the remaining nine bids applied only to the 2022 World Cup, while the rest were initially applications for both.  Over the course of the bidding, all non-European bids for the 2018 event were withdrawn, resulting in the exclusion of all European bids from consideration for the 2022 edition.  By the time of the decision, bids for the 2018 World Cup included England, Russia, a joint bid from Belgium and Netherlands, and a joint bid from Portugal and Spain.  Bids for the 2022 World Cup came from Australia, Japan, Qatar, South Korea, and the United States.  Indonesia's bid was disqualified due to lack of governmental support, and Mexico withdrew its bid for financial reasons.

Argentina at the FIFA World Cup: This is a record of Argentina's results at the FIFA World Cup.  Argentina is one of the most successful national football teams in the world, having won 2 World Cups in 1978 and 1986.  Argentina has been runners up three times in the 1930, 1990 and 2014.  The team was present in all but four of the World Cups, being behind only Brazil, Italy and Germany in number of appearances.  Argentina has also won the Copa América 14 times, one less than Uruguay.  Moreover, Argentina has also won the Confederations Cup and the gold medal at the Olympic football tournament in 2004 and 2008.  Prior to that occasion Argentina had obtained two silver medals in the 1928 and 1996 editions.  On other levels of international competition Argentina has won the FIFA U-20 World Cup a record six times.  The FIFA U-17 World Cup is the only FIFA international competition yet to be obtained.

1979–80 British Home Championship: The 1979-80 British Home Championship saw only the second undisputed victory for Northern Ireland in the British Home Nations international football tournament in 96 years of existence.  It was also the first time since 1970 that Scotland agreed to travel to Northern Ireland, having refused to play there since 1972.  The tournament also finally marked the end of a decade of extremely poor international football results for all the Home Nations.  Apart from disappointing Scottish performances in the 1974 and 1978 FIFA World Cups, no British side had been represented at a major football tournament since England were knocked out by Germany at the 1970 FIFA World Cup.  In 1980, England finally qualified for the 1980 UEFA European Championship and although their performance was unspectacular it did lay the groundwork for the appearance of three of the Home Nations at the 1982 FIFA World Cup in Spain.  The Home Championships thus allowed spectators and coaches an impression of the reorganised British sides and their capabilities in competitive football.

1974 FIFA World Cup Final: The 1974 FIFA World Cup Final was the final match of the 1974 FIFA World Cup, the 10th FIFA World Cup, a competition to determine the world champion among national men's football sides.

The Netherlands opened the scoring via a Johan Neeskens penalty in the second minute, only for Paul Breitner to equalise with another penalty in the 25th minute before Gerd Müller scored the winning goal in the 43rd minute, claiming West Germany's second FIFA World Cup.

Australia 2022 FIFA World Cup bid: Australia submitted an unsuccessful bid for the 2022 FIFA World Cup.  On 2 December 2010 FIFA announced that the event would be held in Qatar.  Australia also lodged a bid for the 2018 World Cup, but withdrew the bid on 10 June 2010.  The 2018 and 2022 World Cups will be the 21st and 22nd editions of the FIFA World Cup.  The bidding procedure to host both the 2018 and 2022 FIFA World Cup began in January 2009, and national associations had until 2 February 2009 to register their interest.  The bid was presented by Frank Lowy, Ben Buckley, Quentin Bryce and Elle Macpherson.  However, due to controversies of Qatar hosting, Australia's bid is possible if FIFA decides to strip Qatar's 2022 hosting rights.
