Tennis star Novak Djokovic has praised his fellow experienced players Andy Murray and Rafael Nadal for the standard of their tennis at the Australian Open.
The 21-time Grand Slam winner has struggled with a hamstring issue he suffered before the tournament began. The 35-year-old received treatment twice on court despite winning his third round match against Grigor Dimitrov 7-6, 6-3, 6-4 to book his place in the last-16.
Murray, aged 35, looked physically exhausted as he fell to a 1-6, 7-6, 3-6, 4-6 third-round defeat to Roberto Bautista Agut. The match came just 39 hours after Murray's epic five-set win against Thanasi Kokkinakis.
