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 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.
