World Cup 2010: Breakdown by SPI and FIFA Rank

Mighty Mike introduced to me the greatest invention in soccer: ESPN's SPI (Soccer Power Index) rankings. For a quick explanation, FIFA's international rankings are based on an absurd 6-years of games. That means that the rankings for these teams still reflect outcomes from 2003 and 2004. In soccer, most of the teams and dominant players change greatly over such a long period of time (i.e. Zidane is no longer on France). Very briefly, ESPN developed the SPI, which is based on recent games but also based largely on player ratings. The ratings of the players not only are based on international games, but also reflect their play on their club teams. A more detailed explanation is also provided on ESPN.

I was even more excited when I discovered that ESPN already used the SPI to determine the average chance of advancing for each team in next year's World Cup! Please note that the SPI is giving a bonus to the African teams, as it assumes that each of these teams will have more fans at the games in World Cup 2010 since it takes place in South Africa.

I'm very intrigued by how much better the SPI can be in comparison to the FIFA rankings. I've gathered a lot of data, shown below.

Based on Average SPI ranking, Group H (Spain) is the toughest group. As Mighty Mike pointed out though, Chile may be ranked artificially high from playing in the mountains and beating everyone there. Groups E(Netherlands) and Group D (Germany) are close behind.

Based on Standard deviation by SPI, Group D (Netherlands) has the 4 teams closest to the same rank.

Based on Average FIFA ranking, it's Group H again, followed by Groups E, D, and C. What's interesting is how different the rankings are between FIFA and SPI. For example, in Group H, Chile is ranked 9 spots higher in the SPI and Honduras 13 spots. Switzerland is ranked 13 spots lower though.

Based on Standard Deviation by FIFA, Group C (England) has the 4 teams closest to the same rank.

If you look strictly at SPI vs. FIFA to determine who would advance there would only be 2 differences if using the SPI (Uruguay over Mexico and Nigeria over Greece)

Of course there's one fact that remains true no matter what: the toughest 3 teams are in Brazil's Group: Brazil, Ivory Coast, and Portugal should be an amazing three-team race as each are capable of making the quarter-finals at least.

This is something that I always wondered about. FIFA ranking has always been a bit subjective. One thing for sure, if both indexes are high for any particular squad, they will be tough to beat.
