One of the world’s biggest football stars Cristiano Ronaldo was in Madrid last night to unveil the inaugural Castrol Rankings – the world’s first rankings based on the actual performance of every football player across Europe’s top five leagues. Whilst all other football rankings are based on opinion, these rankings have been created using 100% objective analysis and accurate data to measure every pass, every tackle and every single move of over 2000 players. It hopes to draw a line under the age-old debate about who are the best performing players, and may even answer the much-disputed question of who is the greatest current footballer? 12 months in development, the Castrol Rankings are updated on a rolling monthly basis, so from now on football fans can regularly check whether Kaká is out-performing Gerrard, or whether Messi is proving more effective than Thierry Henry. Fans can also customise the Rankings by player nationality, position or club, allowing them to compare the players or teams they support.
