Murray's retirement news shocks Federer, hurts Novak Djokovic

MELBOURNE, Jan 13 (AFP): Roger Federer admitted Sunday he was shocked that tennis was to lose "legend" Andy Murray this year while long-time friend Novak Djokovic said the bombshell news had "hurt" him.
Both paid tribute to the former world number one on the eve of the year's first Grand Slam with Federer adding that the Scot should be "incredibly proud" of what he had achieved.
Murray on Friday admitted that his chronic hip injury had not been eased by surgery a year ago.
He then choked back tears and broke down as he revealed that he hoped to end his storied career at Wimbledon, but the Australian Open beginning Monday could be his last event because the constant pain was so bad.
"I was disappointed and sad, a little bit shocked, to know now that we're going to lose him at some point," Federer told reporters.
"But we're going to lose everybody at some point. It's just now that it's definite," he added, acknowledging that the era of the "Big Four"-himself, Djokovic, Rafael Nadal and Murray was drawing inexorably to a close.
"Of course, it hits us top guys hard because we know Andy very well," the world number three said of the three-time Grand Slam champion and double Olympic gold medal winner.
"He's a good guy, Hall of Famer, legend. He won everything he wanted to win. Anybody would substitute their career with his. He's a great guy."
World number one Djokovic played Murray in a practice match three days ago and said it was obvious that there were serious problems.
"You didn't need to be on court to notice that he's struggling, that he's not moving as well as he normally does," said Djokovic, 31, who is just a week younger than Murray.
"We've seen so many years of Andy Murray being one of the fittest guys on the tour, running around the court, getting always an extra ball back.
