As the embarrassing Capello Index saga rumbled on today, the England manager has been reminded that he must run any future business ventures past the Football Association first in an effort to avoid a repeat.

As with other FA employees, it is understood Fabio Capello's contract contains a clause requiring him to obtain prior approval for external business ventures. For whatever reason, however, and with his reputation within the organisation riding high following England's impressive qualifying campaign, it was ignored when the Italian agreed to contribute to the Capello Index venture.

Many at the FA were unaware of the imminent launch of the website, while others attempted unsuccessfully to persuade him to postpone the launch until after the World Cup finals.

At the launch in May he was described as the co-founder of the player-rating site with the Italian businessman Chicco Merighi, although the England manager claims not to have received any payment for his involvement and details of their agreement remain unclear. But Capello will now be expected to stick strictly to the terms of his contact in the unlikely event that he should wish to embark on any similar venture over the remaining two years of his deal.

The website, which rates players according to a complex formula that was developed using Capello's expertise but does not rely on his personal assessments, raised eyebrows not only because of the proximity to the World Cup, but also because it appeared to be out of character.

In comparison to some of his predecessors, notably Sven-Goran Eriksson with classical music CDs and computer games, Capello had displayed a reluctance to augment his salary with external endorsements or business ventures.

An increasingly frustrated FA today continued to communicate with Capello's Italian advisers, led by his son and lawyer Pierfilippo, as it in turn attempted to get the website's creators to remove the England manager's name and likeness from the site.

After much toing and froing, the ratings for England players were finally removed on Tuesday, but the site remains live and its creators appear to have little intention of removing the references to Capello. Since Monday night, visitors to the site have been greeted by a note explaining Capello's role.

"The Capello Index cannot, and must not, be summarised as 'The vote given by Capello' to the players, but is the result of a system which is capable of analysing and evaluating the actual performance adding various scientific variables," it said.
