Novak Djokovic and Andy Murray haven't decided whether to continue their player-coach partnership. Djokovic hired his former rival as his coach for the Australian Open, where the Serbian reached the semifinal round.

Djokovic retired hurt in his Australian Open semi-final against Daniil Medvedev after struggling with a muscle tear in his upper leg, having been in obvious discomfort throughout the opening set.

Novak Djokovic has said he and Andy Murray will "cool off" before making a decision on whether they decide to continue to work together after the Serb's Australian Open exit.
