A new "bionic ball" tested at the Club World Cup in Japan could soon be a regular feature at Fifa football tournaments, its developers claimed.

The technology, involving magnetic sensors that determine if the micro-chipped ball has crossed the goal line, has worked well so far, according to co-designers Adidas and Cairos.

The developers said feedback from the players at the seven-team competition had been positive.

"We are very satisfied," Adidas' chief of Fifa Affairs, Gunter Pfau, said in Tokyo when he demonstrated the ball's qualities.

"No ball was damaged. All the systems have worked."

An implanted microchip sends an instant signal to the referee's watch to indicate if the whole of the ball has crossed the line.

Fifa hopes the breakthrough will eliminate controversy and wants to use the technology at the 2010 World Cup.
