Andy Murray: The Man Behind the Racquet documentary

It was a moment that will make last year's Wimbledon live long in the memory - a tearful Andy Murray addressing the Centre Court crowd following his defeat by Roger Federer in the men's singles final.

Murray stood to become the first Brit to claim the title since Fred Perry in 1936, but the British number one was beaten in four sets as Federer captured a seventh singles crown at the All England Club.

After collecting his runners-up plate, Murray took the microphone from BBC Sport's Sue Barker - only for his emotions to take over.

"Right, I'm going to try this and it's not going to be easy," began the Scot, choking back the tears,

Roared on by the crowd, he congratulated Federer on another title but broke down again when thanking his fans.

Murray discusses that moment in a BBC One documentary - Andy Murray: the Man Behind the Racquet - to be screened this Sunday at 22:25 BST.

"I've seen loads of great players in the locker room crying but you don't always see it in front of the crowd," he told Barker.

"But then obviously when you lose in a final like that and you have to speak, then it's tough sometimes to hold the emotions together."

Murray's girlfriend, Kim Sears, admits it was a heartbreaking moment.

"There were a lot of tears," she says.

"It was just horrible seeing someone you care about going through that. The immediate aftermath wasn't pretty."

Tim Henman, John McEnroe, Andre Agassi and Kevin Spacey also give their reaction to Murray's tears.

"I thought it was sad on a number of levels," says former British number Henman, who reached four Wimbledon semi-finals.

"Obviously because he was incredibly disappointed, but I find it slightly sad it took him to cry in his acceptance speech for people to suddenly take a step back and go: 'Wow, you know he has got a heart, he is a sensitive soul'."

Agassi, who won Wimbledon in 1992, said his view of Murray changed as a result of what he witnessed that day.

"I liked seeing it because you want to see somebody care, watch them communicate how much that moment meant," said the American. "It made me want to root for him more, no question."

Spacey, a friend of Murray and a big tennis fan, feels the incident was a defining moment for the Scot.

"Boy, what class and grace that he showed," said the actor, a two-time Oscar winner.

"That, in many ways, humanised Andy for the public and the press."
