Djokovic was born on 22nd May 1987 in Belgrade, Socialist Federal Republic of Yugoslavia. He began playing tennis at the age of four.
He caught the eye of Yugoslav tennis player Jelena Gencic, who described him as “the greatest talent I have seen since Monica Seles”. She took him under her wing for six years until he left for Germany to train at the Pilic tennis academy in pursuit of higher competition.
He represented the Yugoslav national team, and reached the final of the 2001 Junior Davis Cup for players under 14, where he lost his match in singles.
Djokovic turned professional in 2003. He played his first tour level tournament at Umag in 2004, and had to face defeat in the round of 32. He made his first Grand Slam appearance at 2005 Australian Open.
Djokovic won his first ATP title at the 2006 Dutch Open without losing a set. The same year, he helped Serbia and Montenegro clinch a decisive win against Great Britain in the Davis Cup.
Djokovic won his first Master Series title at the Miami Open in 2007. He was also the runner-up at the Indian Wells which saw him break into the top ten world ranking.
At the Rogers Cup that year in Montreal, Djokovic defeated World No. 3 Andy Roddick in the quarterfinals, World No. 2 Rafael Nadal in the semi-final and top ranked Roger Federer in the final and became the first player after Boris Becker to have defeated the top three ranked players in a single tournament.
In 2008, Djokovic won his first Grand Slam title at the Australian Open. He also won the bronze medal at the 2008 Beijing Olympics.
In 2011, Djokovic won three Grand Slams, starting with the Australian Open, Wimbledon and the US Open and also won a record five ATP Master 1000 titles.
Djokovic repeated his feat by winning the three Grand Slam titles in 2015 again.
Djokovic has been coached by the likes of Boris Becker, Andre Agassi, Mario Ancic, and most recently Radek Stepanek.
Djokovic has won 12 Grand Slam singles titles, the fourth most in history of men’s tennis. He has also won 30 Master 1000 Series titles; an all-time record he shares with Rafael Nadal. He was part of the Serbian team that won the 2010 Davis Cup.
