Nick Kyrgios makes stunning Roger Federer, Rafael Nadal and Novak Djokovic claim

Who did he think he was, Roger Federer?

A women's final a year ago featuring two players aiming for their first Grand Slam title finished with Wozniacki holding off top-ranked Simona Halep for the championship.

While two months' pregnant, Williams claimed a record seventh Australian Open title in the professional era in 2017 but missed out on her title defence while on maternity leave.

Zverev, 21, starts the Australian Open full of confidence after an impressive warm-up to reach the final of Perth's mixed teams Hopman Cup, despite his awful record at Grand Slams.

Kyrgios also compared Murray to Djokovic. Then there's a resurgent Rafael Nadal, the likes of Cilic and Sasha Zverev.

Murray has won Wimbledon twice during his career and Federer is hoping the three-time Grand Slam champion can play long enough to say goodbye on the grass courts where the Swiss has won a record eight titles.

Tracey Crouch, the United Kingdom sports minister when Sir Andy claimed his second Wimbledon title in 2016, said she was "sorry" to hear of his retirement.

Current British number one tennis star Kyle Edmund said: 'For me he's been my biggest role model out of any tennis player.

'Making that decision, I think I can get through to this at Wimbledon, that's when I'd like to stop playing.

'If it is my last match, I want to try and enjoy it - enjoy the whole experience, which is maybe something during my career that I've not done.

She added: "I was quite sad and shocked that he was retiring but still happy that he's going to be able to rest his hip and not have to worry about competitions".

When asked for his views on Andy Murray's sudden retirement announcement, the 17 times Grand Slam victor said that it is "bad news".

"It's sad for me, but for all sport, because Andy is a very respected and likable guy around the locker room", Djokovic said.

Djokovic won his third US Open in September to put him on 14 Grand Slams - three behind Nadal and six behind Federer. As victor of the last two majors, he's a strong contender to win in Melbourne Park again and become the first man with three streaks of three or more consecutive Grand Slam championships. "I am confident it's going to work well". It must have been a very long couple of years for him.

"I talked to him a little bit yesterday actually, ran into him at the hotel". He can play well in fast courts.

"Of course, she's not number one in the world, and I have a lot of respect for the number one but I still feel that if Serena plays her tennis and she's herself 100 per cent, I still think she's the best. There are many things why I look up towards her", said the Londoner, who is ranked 131 in the world. It is the defending champion's privilege. He said, "I didn't realize that Amelie would find herself up against such criticism and prejudice...." "I can't believe it's already been a year. It doesn't feel like it to me".

What few knew as her season drew to a close was that the indefatigable Dane had been diagnosed with rheumatoid arthritis, an auto-immune disease that can cause swelling and pain in the joints.

Wozniacki's vanquished opponent in last year's final, Simona Halep, arrives in Australia with the world number one ranking and her confidence overflowing after winning the French Open.

Honest, courteous and self-deprecating, Murray always has been well-liked by his fellow players, as nearly all of them who were scheduled for media day here Saturday noted.
