Castrol, Official Sponsor of the FIFA Confederations Cup Brazil 2013, are experts in using pioneering technology and data analysis to understand the performance of their oils and have used similar expertise to create the Castrol Index, the definitive system for rating player performance.

Previously used at the FIFA Confederations Cup 2009 and the 2010 FIFA World Cup™, the Castrol Index uses the latest FIFA tracking technology to capture data on each player, which will then be analysed by a team of Castrol Performance Analysts. Every pass, tackle and move on the field is measured and assessed to see if it has a positive or negative impact on a team's ability to score or concede a goal. The team of Castrol Performance Analysts crunch all the data to award each player a Castrol Index score out of 10 - the stronger the player's performance, the higher their score.

In South Africa in 2009, Brazil’s Lucio topped the Castrol Index and in 2010 it was Spain’s Sergio Ramos who came out on top. The FIFA Confederations Cup 2013 Castrol Index will be published at FIFA.com/castrolindex after each round of matches, so check the site from 18 June to find out which players will grab the headlines this time around.
