Novak Djokovic entered the tennis world in 2003 and had no idea what was to be in store for him over the next 20 years.
He worked exceptionally hard to improve his game to become one of the game’s top players and win some big titles.
For several years he stood in the shadow of Roger Federer and Rafael Nadal, the two dominant forces in the second half of the 2000s into the early 2010s.
But the Serbian rose from being the hunted and went on to become arguably the greatest player in men’s tennis history.
