Fastest hat-trick in an international football (soccer) match
According to Official Guinness Records,
Japanese international Masashi 'Gon' Nakayama scored a hat-trick in 3 min 15 sec against Brunei during an Asian Cup qualifing match played on 16 Feb 2000. Nakayama netted on one minute, two minutes and three minutes fifteen seconds, bettering the 62-year-old mark set by England's George William Hall, who scored three in 3 minutes 30 seconds against Ireland at Old Trafford, Manchester, UK on 16 November 1938. Nakayama is Japan's veteran striker, who also holds the record for most consecutive hat-tricks in league football (four) and is the only Japanese to score during the World Cup Finals, during Japan's 2-1 defeat by Jamaica at France '98.
