"I don't think they should pick him," Campese said. "He's not really the Tim Horan of old. It takes a lot of guts and hard work to get where he is, but he's not quite the same player.''
Campese, the world record holder for try scoring, was criticised by the Australian chairman of selectors, Paul McLean, who said that his statements were "totally irresponsible".
Michael Jones, one of the world's best flankers, has been omitted from the final All Black trial for World Cup places because of his religious beliefs.
Jones is a Christian who declines to play on Sundays and World Cup matches are due to be played on the sabbath.
