The tennis players' association co-founded by Novak Djokovic has sued the main groups that run the sport in a bid to gain more money and control.

Novak Djokovic has prepared very well for his debut in Indian Wells today, where he will face Dutch ace Botic van de Zandschulp. The latter took advantage of Australian ace Nick Kyrgios' retirement in the previous round and will be able to play with nothing to lose against an opponent who has made tennis history,

The lawsuit seeks a jury trial and wants players to gain access to more earnings, arguing that the governing bodies that oversee the four Grand Slam tournaments and other professional events “cap the prize money tournaments award and limit players’ ability to earn money off the court.
