Andy Murray is crowned US Open champion in 2012
We take a look back at Andy Murray's greatest moments as the former world No 1 undergoes successful right hip surgery on a lingering hip problem.
From US Open junior champion in 2004 to the 'King of New York' and Olympic gold back-to-back and then the ultimate dream of winning Wimbledon - not once, but twice.
The Scot has been through every possible emotion. He is all too familiar with losing in major finals too - five times in Australia, once in New York  and at his beloved All England Club in 2012.
We take a look back at some of the greatest moments of Murray's magical career, starting with his finest victory on Sky Sports as he contemplates surgery on his problematic hip which has kept him out of action since losing a tough five-setter to American Sam Querrey in the quarter-finals at Wimbledon.
US Open champion 2012
Murray emerged from the shadow of the great Fred Perry to become Britain's first Grand Slam winner in 76 years after a gladiatorial battle against Novak Djokovic.
It was a spellbinding 7-6 (12-10) 7-5 2-6 3-6 6-2 victory over the world No 1 that took four hours and 54 minutes on Arthur Ashe Stadium and in front of celebrity spectators including Sir Alex Ferguson and Sir Sean Connery.
Murray beat old foe Djokovic at Flushing Meadows
It was a marathon first set at 87 minutes that featured the longest tie-break a US Open final has ever witnessed as Murray edged Djokovic 12-10.
After Djokovic restored parity by taking the fourth set to send the final into a deciding-set shootout, Murray took a career-defining bathroom break. That helped him refocus and to "leave the court with no regrets".
Murray came out and showed incredible resilience to break the Serb three times before sealing a remarkable victory.
When Djokovic smashed a return long on championship point, the crowd rose to their feet to recognise Britain's history-maker.
Wimbledon 2013 & 2016
Andy Murray - Wimbledon champion in 2013
Murray ended Britain’s 77-year wait for a men’s singles champion after defeating Djokovic 6-4 7-5 6-4 just 12 months after being denied his maiden major in London.
The 26-year-olds were playing each other in a Grand Slam final for the third time in the previous four majors, with Murray winning at Flushing Meadows and Djokovic taking the 2013 Australian Open five months prior to Wimbledon.
Murray was prepared to go the distance against the six-time Grand Slam champion on a sweltering summer's day.
It was a match dominated by lengthy baseline rallies the Scot let three championship points slip away. On the fourth opportunity, Djokovic slapped a weak backhand return into the net and the celebrations - mixed with plenty of relief - could finally begin.

He had to wait three years to repeat the feat with a hard-fought 6-4 7-6 (7-3) 7-6 (7-2) success over Canadian sixth seed Milos Raonic.
By nullifying Raonic's power, Murray became the first British man to win multiple Wimbledon singles titles since Fred Perry in 1935.

Murray shows off his gold medal at London 2012
Murray had never beaten old nemesis Roger Federer in a best-of-five-sets match going into the gold medal contest at the 2012 London Olympics.

In front of a partisan Centre Court crowd, Murray showed immense focus to claim a memorable 6-2 6-1 6-4 victory.
Murray fittingly described this victory as the biggest in his career and after his win admitted that athlete Mo Farah had given him the motivation he needed to win gold after his amazing victory in the 10,000m.
It was amazing to see Mo Farah run his final 400 metres in 53 seconds when I can only do it in 57 seconds when I'm fresh. That gave me the motivation to try to win the gold medal, because I wanted to be part of it if I could.
Farah inspired Murray
"I watched the athletics last night, and it was unbelievable,” Murray said. "It was amazing to see Mo Farah run his final 400 metres in 53 seconds when I can only do it in 57 seconds when I'm fresh. That gave me the motivation to try to win the gold medal, because I wanted to be part of it if I could."
It was the first time since Josiah Ritchie in 1908 that a British man won an Olympic singles gold medal in tennis.

In a battle of the 21-year-olds, Murray was meeting Djokovic for the first time in the final on the ATP World Tour and at a Masters 1000 event too.
It was a hugely significant victory, which encompassed some inspired tennis as power, strategy, fitness and near-genius won the day.

He also moved to No 2 in the world ahead of Roger Federer said: "If this was the US Open, we'd have to play another couple of sets like that, which isn't easy."
Best of the Rest
With Miami being regarded by many as the 'fifth major' at the time, Murray picked up his third Masters title, following wins in Cincinnati and Madrid in 2008, under the searing Florida sunshine.

"It was a brutal, brutal match. Both of us were kind of on our last legs," Murray said. "It was a good job it wasn't a best-of-five-set match, because I don't know how the last few sets would have ended up."
"It was one of the toughest matches I have had to play in a Masters Series, for sure," he added.
Murray was greeted at the net by Tommy Robredo's middle fingers following a colossal 3-6 7-6 (9-7) 7-6 (10-8) victory which lasted three hours and 20 minutes.
