Andy Murray believes his Australian Open win over Grigor Dimitrov shows how much he has improved physically.
The British number one won a gruelling late-night contest with the Bulgarian 6-4 6-7 (5-7) 6-3 7-5 in three hours and 32 minutes to reach his sixth consecutive Australian Open quarter-final.
Murray will face Australia's Nick Kyrgios in the last eight.
