There have been plenty of theories for the 24-time Grand Slam champion’s lack of form, and Rafael Nadal ’s long-time coach Carlos Moya has now suggested that Djokovic is feeling “empty”. However, the former world No. 1 doesn’t want to rule him out for the upcoming French Open.

May 13 (UPI) -- Novak Djokovic and coach Andy Murray ended their partnership after six months, they said Tuesday.

Andy Murray and Novak Djokovic will no longer be working together after the British legend’s five-month spell as the Serbian icon’s tennis coach. The pair announced the split on Tuesday – just 12 days before the French Open – despite Djokovic previously stating that he hoped to continue his partnership with Murray through Roland-Garros and Wimbledon this year.
