Andy Murray has battled his way into the semi-finals of the men's singles at Wimbledon after being on the brink of defeat against Spain's Fernando Verdasco.
Murray paid tribute to the "unbelievable atmosphere" inside Centre Court, while thousands more urged him on to victory on nearby "Murray Mount" after he lost the first two sets.
The second seed claimed victory by 4-6 3-6 6-1 6-4 7-5 and will face Poland's Jerzy Janowicz, the 24th seed, on Friday for a place in the men's final.
Murray's girlfriend Kim Sears urged him on along his support team in the final stretch, while Sir Alex Ferguson cheered his countryman on as he followed the game intently from the Royal Box.
Verdasco, who is only the Spanish number nine, stunned the crowd by winning the first two sets 6-4, 6-3.
After the match Murray described the 29-year old as an "incredibly dangerous" player.
Asked about his own emotions during the match, Murray said: "I made some poor choices. He served fantastically well. He's a very, very good player and he's incredibly dangerous."
He told the BBC after the five-set victory: "There's been a lot of matches where I've been behind and managed to turn it round; I don't know if it is the most emotional match, but it was an unbelievable atmosphere and great to get through."
A sweary mid-match outburst by Murray prompted a Twitter backlash after it was broadcast on the BBC.
The Scot was caught on camera apparently mouthing: "F****** w*****, what are you doing?" to himself as he struggled to fight back against Verdasco.
BBC commentator Andrew Castle played down the outburst, saying: "I do apologise for the language, of course, but you can understand the frustration that Andy Murray feels at this point - he really is torturing himself."
But Twitter users suggested Murray's behaviour would not have been tolerated during a televised football match.
