In the summer of 1993, at 6 years old, Djokovic was spotted by Yugoslavian tennis legend Jelena Gencic at his parents' sports complex. Gencic then worked with Djokovic for the next six years. During this time, the war in former Yugoslavia and the bombing of Belgrade meant that, for almost three months, Djokovic and his family would spend a few hours in the middle of each night in the basement. Djokovic has said that the hardships of war drove him to pursue tennis with even greater determination. At 13, he was sent to the Pilic Academy in Munich, Germany, to pursue higher levels of competition. In 2001, at age 14, he began his international career.
