Title: How Our Club Soccer Predictions Work Author: Jay Boice Type: Blogpost Institution: FiveThiryEight Publication Date: 2Jul2020 Topic: Team Strength Abstract: The forecasts are based on a substantially revised version of ESPN’s Soccer Power Index (SPI), a rating system originally devised by FiveThirtyEight editor-in-chief Nate Silver in 2009 for rating international soccer teams. We have updated and adapted SPI to incorporate club soccer data going back to 1888 (from more than 550,000 matches in all) that we’ve collected from ESPN’s database and the Engsoccerdata GitHub repository, as well as from play-by-play data produced by Opta that has been available since 2010.
