Hockey legend Ric Charlesworth has resigned his post of technical advisor with Indian hockey and flown back to Australia, top officials said on Friday.
Charlesworth, 54, quit four months after being formally given the job in March to revive Indian hockey after the eight-time Olympic champions failed to qualify for the Beijing Games for the first time.
"Ric has written to us that he does not want to continue," Indian Olympic Association secretary-general Randhir Singh said.
Aslam Sher Khan, who heads the ad hoc committee running the Indian Hockey Federation (IHF), said Charlesworth was not happy with the way the game was being run in the country.
"He was not too happy with the system in India and preferred to resign," said Khan, a former international. "We tried to convince him to stay but he seemed to have made up his mind."
Charlesworth had come to India as part of an initiative by the sport's world governing body to revive hockey in the country.
He played in four Olympics between 1972-1988 - missing the Western-boycotted Moscow Games in 1980 - and was part of the Australian team which won the World Cup in London in 1986.
After retiring in 1988, Charlesworth took up coaching and moulded the Australian women's squad, nicknamed the Hockeyroos, into one of the most formidable teams in the sport's history.
The multi-faceted Charlesworth, a doctor by profession, was also a member of Australia's parliament for 10 years until 1993 and played first-class cricket for Western Australia.
