T he portrait of Greg Chappell on the left is when the master batsman was 21 , a year before he made his debut in the Perth Ashes Test in 1970. Chappell then looked like a soldier. The picture on the right is of Chappell at age 65. Still a disciplinarian to the core, Chappell's moustache has given way to a clean shaven look and in fact the receding hairline gives him the half-bald look.<p></p><p></p>Chappell was one of the greatest batsmen of his generation . The younger brother of Ian Chappell , Greg led Australia in 48 Tests between 1975 to 1983 . Post retirement in 1984, Chappell has been involved with the game in various capacities. He has served the sport as a commentator, coach and selector. He was the Australian selector from 1984 to 1988 and the South Australian coach in the 1990s. In 2005, he was also appointed as the coach of Indian team . It was probably the unhappiest phase of his career, as his differences with captain Sourav Ganguly led to a public battle between the two.<p></p><p></p>The under-arm bowling incident was a blot in his career as his win-at-all-cost approach made him ask his younger brother, Trevor, roll the last ball of the game ball along the ground to prevent the New Zealand batsman from hitting a six and winning the One-Day International. His tenure as Team India's coach did nothing to help his image as a controversial man.
