England manager Fabio Capello has defended his involvement with a website that will rate his players during this summer's World Cup finals.
On Monday the Italian, 63, launched the 'Capello Index', which will give performance data on all Cup stars within two hours of games ending.
Capello is also a co-founder in the venture, along with Chicco Merighi, the founder of an online gambling company.
"It's not only about money, my interest is in football," said Capello.
Players' performances will be marked out of 100 - based on computer analysis devised by the former Roma, Juventus and Real Madrid boss over the last two years.
Capello believes the index will be "good for the fans".
Points are earned depending on the area of the pitch they competed in and the importance of the match.

Capello will hope the next four weeks bring the stability and continuity required to plan for success in South Africa
A four-week trial of the index - limited to players from Arsenal, Chelsea, Liverpool, Manchester City, Manchester United and Tottenham Hotspur - rated Ledley King, Michael Dawson and Sol Campbell as the best English central defenders ahead of John Terry and Rio Ferdinand.
And Chelsea midfielder Joe Cole, tipped to miss out on a place in Capello's 30-man provisional squad for South Africa on Tuesday, was ranked as the third best English midfielder.
However, Capello said the index would provide detailed information for fans to analyse.
"It is really important to know the players outside the pitch," he said at the launch at the London Stock Exchange.
Capello's business partner Merighi is chairman of Goal Ventures Ltd, a company that owns goaltipwin.com, an online sports betting website.
The website will also rate players' performances in the Premier League next season.
