How the Castrol Index is calculated
The Castrol Index tracks every touch of the ball by a player on the field and assesses whether it has a positive or negative impact on a team’s ability to score or concede a goal.
A key factor for all areas of performance in the Castrol Index is the zone on the pitch where the action takes place. Players receive points for each successful pass they complete, but the number of points awarded depends on which zones the ball is passed from and received.
The Castrol Index records the difference a pass actually makes – so a long pass from midfield into the danger area would be rewarded very highly, whereas a short pass further down the field would receive fewer points.
Similarly, misplaced or intercepted passes are penalised depending on the danger the team is placed in by the wayward pass.
The Castrol Index is also able to split up the rewards of a goal between penalising the goalkeeper for letting in a shot he should have saved and rewarding the attacker for scoring a goal.
The number of Castrol Index points awarded for tackles, interceptions and blocked shots also depends upon the zone in which they are made. Successfully taking the ball from a striker in your own penalty area will earn more points than a tackle out on the wing.
Conceding free kicks and penalties will result in point deductions.
Castrol’s team of performance analysts crunch all the data and award each player a Castrol Index score out of 10.Ä‚€š' As we progress through the Qualifiers, a players’ mark out of ten will be cumulative based on the number of games he plays – the higher the score the better the player’s performance.
The Castrol Index rankings are not a basic measure of talent.Ä‚€š' They are a measure of performance based on the actual contributions players make during the 2010 FIFA World CupTM European Qualifiers.
As a result, they are free from any prejudices which might lead to some players’ actions being overestimated and others underestimated.Ä‚€š' They will simply judge players on what they’ve done and, we hope, stimulate further debate around who the form players are in the competition.
