FIFA World Ranking system (2006–2018)
The 2006–2018 FIFA men's ranking system was a calculation technique previously used by FIFA for ranking men's national teams in football. The ranking system was introduced by FIFA after the 2006 FIFA World Cup, as an update to an earlier system, and was replaced after the 2018 World Cup with a revised Elo-based system.
The system, like the previous ones, is extremely similar to that of a league, though with changes made to ensure that it is still representative of the teams' performance despite playing differing numbers of matches per annum, and the differing strength of opposition that teams have to face. The factors taken into account are as follows:
- Match result
- Match status
- Opposition strength
- Regional strength
Teams' actual scores are a result of the average points gained over each calendar year; matches from the previous four years are considered, with more weight being given to recent ones.
