Blatter said Adidas was aiming to get a system in place for the finals, which begin on June 9 2006 which involves balls being fitted with electronic chips which send bleeps to a device in the referee's ear when the ball has crossed the line.

"I am convinced it will be ready for the World Cup," he told l'Equipe sports daily.

FIFA are to experiment with the technology at the world under-17 championship in Peru from September 16 to October 2.

But he ruled out the use of video, pointing to the controversy surrounding Liverpool's goal against Chelsea in the second leg of their European Cup semi-final as a reason why TV cameras should never be used to help referees on goal-line disputes.

"They had 12 cameras there and you could not see. We believe the human side of the game should be kept," he added.

He said they had revised their selection and training of referees after cases of "appalling" refereeing at the 2002 World Cup finals.

Teams of referees and linesmen, who regularly work with each other, have been put together for the tournament and are already attending regular training seminars in Germany.

"They will only work in trios that have been pre-selected. We have been tough on them so that there is uniformity of the interpretation of the laws. I take part of the responsibility for last time. I hope we will have the best referees on the market and avoid the kind of situations we had in 2002."

Blatter believes the 2010 World Cup in South Africa is set to make more money from TV rights than next year's tournament.

"The projection is that the interest in the market will be higher than the value obtained in Germany in 2006. The World Cup ratings are higher than the Olympic Games and people realise it is a good product with teams with national identity which is no longer the case in most clubs.

"The market also trusts the organisation of the South Africans."
