Novak Djokovic and coach Andy Murray ended their partnership after six months, they said Tuesday. Djokovic announced in November that he hired Murray. The 24-time Grand Slam winner was ranked No. 7 in the world at the time.

Jim Courier suggests Novak Djokovic may have been looking for "a spark" ahead of the French Open and Wimbledon and figured out that ditching Andy Murray could help him in his goal. On Tuesday morning European time, the record 24-time Grand Slam champion announced he and the British tennis legend were ending their partnership after six months.

Justine Henin suggests Novak Djokovic realized Andy Murray couldn't anymore provide him the motivation he needed and that's what prompted the current world No. 6 to make such a huge decision ahead of the French Open.
