Former Australia coach Alan Jones said incumbent Robbie Deans was out of his depth, claiming the best way he could improve the Wallabies was to shut up and stay at home in bed.
Jones, who was in charge of the rugby team from 1984-87, labelled Deans a "provincial coach" who had squandered the playing talent at his disposal, resulting in a gulf in class with arch-rivals the All Blacks.
Jones laid the blame for the Wallabies' recent failures squarely on Deans, saying: "Our team is badly coached, there's no other way of putting it."
"Sometimes you are better off being not coached than badly coached," he said. "The whole system here is a failure and the players are suffering ... basically, at this level, he's not up to it."
Australia's last victory at Auckland's Eden Park came in 1986, when Jones was at the helm.
Asked what advice he would give Deans, Jones replied: "Put them on the paddock and let them organise it … shut up and stay at home in bed."
Jones also took issue with Deans' nationality. "Who the hell invited a New Zealander to coach Australia? That's ridiculous," he said.
