Tennis has seen a multitude of talented players springing from Eastern Europe over the past decade, and Novak Djokovic is arguably the most talented of those who have emerged. His aggressive baseline game and all-round court skills have improved rapidly, propelling him to the pinaccle of the men's game. Novak has stormed to World Number 1 in the rankings and, as of September 2011, holds three of the four Grand Slam titles (US Open, Australian Open and Wimbledon).
