Wimbledon 2016: Who is Andy Murray's next opponent John Millman?

Andy Murray continues his campaign for a second Wimbledon title against John Millman, but what do we know about his third-round opponent?

Whether he wins or loses against Murray on Saturday, it is fair to say it has been a good week for Millman.

Not only has the 27-year-old made the third round of a Grand Slam for the second time in his career, he also found out on Thursday, after his win over 26th seed Benoit Paire, that he had been selected to represent Australia at the Olympics this summer.

With Nick Kyrgios and Bernard Tomic not competing in Rio, Millman is Australia's highest-ranked singles player available.

But he needed approval from the International Tennis Federation to be eligible as he hadn't played Davis Cup for Australia. That came through midway through his match with Paire.

"It means the world to me to be able to represent my country at the Games," said Millman.

"I'm buzzing for that, and then to be able to go out there and put together a pretty good performance out there was awesome. I live to fight another day here at Wimbledon."

Millman will probably appreciate the occasion of Centre Court and the Olympics more than most.

The Queenslander has only recently broken into the top 100 after several injuries that threatened to derail his career.

Retirement was even a consideration after an injury five years into his professional career, which had started in 2006.

"I was getting frustrated with it all," he said. "But the thing that motivated me the most was the fact that I knew I still hadn't reached my potential."

In 2013 he then required shoulder surgery that forced an 11-month lay-off and saw him work in a finance firm.

"It was definitely a change of pace, putting on a suit and going to work," he said. "It's not always guaranteed you come back from a torn labrum. Your shoulder's a pretty vital part of tennis and I literally had to build it up from scratch again."

But persistence has paid off for the Australian.

After getting back on the circuit at Challenger Tour level, he went through qualifying at Wimbledon last year, eventually losing to Marcos Baghdatis in the second round proper in five sets.

In 2016 he has largely been back on the ATP Tour, with his best result coming at the Australian Open when he reached the third round.

Prior to Wimbledon he had not shown much form on grass, only winning two matches, but he battled past Albert Montanes in five sets in the opening round and then beat Paire in four - watched by Australia Davis Cup coach Lleyton Hewitt - to set up a meeting with Murray.

"It's going to be great," he said. "It's what you dream of, playing on the biggest courts against the biggest players. I feel I deserve to be there. The third round at Wimbledon is uncharted territory for me, but we start out at zero-all. I have never been one to go out with an intimidated mindset before I play the game."

Murray and Millman have met only once before - in Brisbane in 2013 - with the Australian winning the first set but losing 6-1 5-7 3-6.

While Murray has regularly challenged for major titles since that match, Millman is playing in only his seventh major main draw. Unsurprisingly, he is relishing the occasion.

"I would never have dreamed a couple of years ago that I would ever be in this position, so I plan to make the most of it," he said.
