Andy Murray says his shock defeat by world number 50 Mischa Zverev at the Australian Open is tough to take.
The German played aggressively to surprise Britain's world number one and register a 7-5 5-7 6-2 6-4 victory.
Murray, 29, has never won the title despite reaching the final five times, but was favourite to win after Novak Djokovic was knocked out on Thursday.
"It a tough loss at one of the biggest events and one that I wanted to do better at," Murray told BBC Sport.
"I get a bit of time off now and try to learn from it and try to understand what I could have done a little bit better, and then come back and try again.
