Andy Murray and Novak Djokovic will no longer work together, with the duo announcing their split earlier this week. And four-time Grand Slam champion Jim Courier has offered his theory about the separation.

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.

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.
