Novak Djokovic and Andy Murray maybe didn't kick off their partnership with a triumph but Nick Kyrgios still thinks that the Briton did "an incredible job" in his coaching debut. On Friday, the Serb's bid for a record 11th Australian Open title came to an end in an unfortunate way after a muscle tear forced him to retire after losing the first set of his semifinal against Alexander Zverev.

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.

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.
