After working together for only six months, Novak Djokovic and Andy Murray announced Tuesday that they have ended their player-coach relationship. Shortly after his retirement from playing tennis last year, Murray transitioned into coaching and took on his former on-court rival in Djokovic as his first major client.

Novak Djokovic is splitting with coach Andy Murray, just two weeks ahead of the French Open. The decision comes after Djokovic lost his opening match in his last two tournaments, both on clay.

Novak Djokovic caught the tennis world unawares when he announced that his new coach would also be one of his greatest rivals: Sir Andy Murray.
