Shane Warne's seven sins scuttled his ambition to captain the Australian cricket team, perhaps the only unfulfilled dream of the legendary spinner.
Former Cricket Australia director Damien Mullins said the trouble-prone tweaker "sooner or later... would always let you down".
"You can have different views as to his personal behaviour or about its dimensions or its implications. But my view about his qualifications for assuming high office has been consistent all the way through," he said.
"To put it in simple terms: I knew if he was put in a position of authority, sooner or later he would always let you down," Mullins was quoted as saying by the Herald Sun.
The newspaper was quoting excerpts from the book Inside Story, Unlocking Australian Cricket's Archives.
The book also says Warne's incapacity for accepting responsibility became proverbial and there had always been top-level misgivings about his behaviour.
"On Warne being replaced as vice-captain to Steve Waugh, with Adam Gilchrist inheriting the job in 2000, the minutes of the board meeting listed seven crisply-expressed reasons -- 'Taught a lesson', 'Leadership brings other responsibilities', 'Given opportunities and shown that he can't', 'Not this one issue', 'History of incidents', 'Catalogue of reckless conduct' and 'Responsibility to maintain public confidence'.
"'Not this one issue' refers to the incident two months earlier when a British newspaper ran a lurid story of Warne propositioning a nurse in a nightclub and then harassing her with explicit phone message," the book said.
