#5 Biggest margin of victory in a World Cup qualifying match
Australia holds the record for the biggest margin of victory in a qualifying match against American Samoa. They had defeated them by a whopping scoreline of 31-0 in the 2002 FIFA World Cup qualifiers.
This wasn't the only record created in the match. Australia's Archie Thompson also broke the record for most goals scored by a player in an international match by scoring 13 goals. David Zdrillic, who scored eight goals in the match, became the second highest goalscorer in a single international match since World War I.
To prevent such lopsided victories, a preliminary round for the smaller teams in the qualification was re-introduced. With other federations like the AFC, CAF, and CONCACAF also implementing such measures, it is highly unlikely that this record would be broken.
