Djokovic will be bitterly disappointed having missed out on the chance to secure a historical 21st grand slam at the Australian Open, a feat which his rival and fierce competitor Rafael Nadal beat him to. The Serbian was deported from Australia last month after becoming involved in a row with Australian authorities.
