user: Text: Ledley, 29, broke his leg in early May but was named in the Wales squad and came off the bench against Slovakia.
"Without Sean, I don't think I'd be here," said the Crystal Palace player.
"I'm in one of the best shapes of my life now. I've worked so hard. I've been in an oxygen chamber, up at six o'clock in the morning and not getting home until four or five for weeks."

Wales physiotherapist Connolly is also part of Crystal Palace's medical team and has helped Ledley's rehabilitation since he suffered the injury against Stoke City on 7 May.
The former Cardiff City player came on in the second half against Slovakia and played a part in Hal Robson-Kanu's winning goal.
Ledley's Crystal Palace team-mate and room-mate Wayne Hennessey missed the game in Bordeaux after suffering a back spasm and was replaced by Liverpool goalkeeper Danny Ward.
Hennessey missed training on Monday but Ledley is hopeful the 29-year-old will recover in time to face England in Lens on Thursday.
"Everyone was gutted for him because he deserves to be playing," Ledley said.
"But these last few hours he's moving about and hopefully in the next 24 hours he can get on the training pitch.
"He's worked so hard and been in fantastic form for Palace."
summary: Wales midfielder Joe Ledley says an oxygen chamber, dawn rises and physio Sean Connolly got him to Euro 2016.

Anger? Elation? Frustration?
Or perhaps this response: "It's eight years late, but I'll take it."
That was how Great Britain's Martyn Rooney reacted when it was confirmed he will become an Olympic bronze medallist, eight years late.
At Beijing in 2008, Rooney ran the anchor leg of the men's 4x400m for Great Britain as they finished fourth and missed out on a medal - or so they thought.
Then, in the run-up to this year's Olympics, it emerged that the British team might get a medal after all. The International Olympic Committee used the latest anti-doping technology to reanalyse samples from the Beijing Games.
Among those to test positive for a banned substance was that of Denis Alekseyev, who ran the anchor leg for Russia as they took bronze in Beijing. As a result, Russia have been stripped of their medal.
"I definitely feel that I've been robbed and it's a tough, tough place to be but we are athletes at the end of the day and we're here for medals," said Rooney to BBC Radio 5 live.
Rooney and his 4x400m team-mates are not the only British athletes to receive a belated medal. British record holder Goldie Sayers will also be hoping to collect her bronze from the 2008 Olympics after Russia's Maria Abakumova was disqualified.
Sayers, like Rooney and his colleagues, finished fourth in Beijing, but has been moved up following the decision to strip Abakumova of her silver medal.
If he were to have it his way, Rooney, along with team mates Andrew Steele, Robert Tobin and Michael Bingham, would receive their medals at the World Championships in London in 2017.
"I think it will be incredible to be in the Olympic Stadium with a home crowd," he said. "That would be an incredible occasion for us."
It is not yet clear how they will be presented with their medals, but they will not be the first athletes to be honoured late. With anti-doping technology improving, a number of athletes have been disqualified retrospectively, which means their medals are reallocated.
Those Olympic athletes bumped up to get the medals have gone about receiving them in different ways.
For instance, Australian 50km walker Jared Tallent held his own back garden ceremony, having been confirmed as the 2012 Olympic champion in March after Russia's Sergey Kirdyapkin was stripped of the title for doping.

American shot-putter Adam Nelson, meanwhile, received his gold medal in a food court at Atlanta airport in late 2012.
Nelson was upgraded to Olympic champion eight years after finishing runner-up to Yuriy Bilonoh at Athens in 2004. When Ukrainian Bilonoh's sample was retested in late 2012, it was found to contain traces of a banned steroid.
The American, heading to the airport en route to a work conference, was told to meet an official from the United States Olympic Committee when he got there. It was there that his medal was handed over.
Nelson did get a more appropriate ceremony in 2016 when the United States Track and Field Federation arranged for him to attend the US Olympic Trials, awarded him his medal on the podium, played the national anthem and even organised a fly past by local US military air forces.
Sayers suggested on Twitter that she will not get too excited until she has the medal in her hands.
And as the British Olympic Association has suggested, there are still a few hurdles to clear before that happens. "The next step in the process will kick in once the IOC have received the returned medals, diplomas and medallist pins from the athletes who have been disqualified," a spokesperson said.
That medal presentation, wherever it happens, may be a little while yet. But as Rooney said: "It doesn't matter when we get them, as long as we get them."
summary: It is hard to imagine the turmoil an athlete goes through upon hearing they should have been awarded an Olympic medal eight years ago.
Text: Images of volunteers' brains during nights spent in the lab showed the left side remained more responsive to sound.
This asymmetry, also found in marine animals and some birds, was observed only on the first night in a new place.
And Yuka Sasaki, from Brown University, Rhode Island, said it was possible people could learn to switch off their "nightwatchman" function.
"Human's brain are very flexible," she wrote in the journal Current Biology.
"Thus, people who are often in new places may not necessarily have poor sleep on a regular basis."

assistant: People sleep less well in an unfamiliar place as the brain's left side stays alert for danger, a study suggests.
