Djokovic says he was moved by 'amazing warrior' Murray

Novak Djokovic has described his longtime rival Andy Murray as a "warrior" and says he is "inspired" by the former world No.1's journey back from a career-threatening injury.

Djokovic watched Murray's recently-released documentary that chronicled the Brit's two-year battle with a hip issue that required multiple surgeries and was moved by what he saw.

Just 11 months ago, a tearful Murray told reporters at the Australian Open that he might never be able to play tennis again but the 32-year-old has since undergone a hip resurfacing operation that saved his career. He returned to singles action in Cincinnati in August, and remarkably lifted his first trophy in two and a half years in Antwerp in October.

While his preseason preparations have been hampered by a groin injury sustained late in the year, Murray is planning on contesting next month's Australian Open - something that seemed highly unlikely when he bid farewell to the tournament in Melbourne last January.

"I've seen his documentary about four, five days and it was tough to watch to be honest, as a tennis player, and as someone that knows him for a long time," said Djokovic, who is exactly one week younger than Murray, and has competed against him since they were 12 years old.

"To see what he has been through, I think it was a great insight into his last couple of years and the struggles he had, mental, emotional, physical.

"Just amazing warrior that he is in life really, to be able not to give up after everything that has happened and all the recovery and preparations and trying to heal and play a couple of matches in the whole season and still after everything he's been through in his career and having family at home, not give up on that and have support of the close ones, it's really impressive and inspiring."
