Andy Murray will play Roger Federer for the Olympic gold medal on Sunday, and he cannot take the smile off his face.
The 25-year-old was roared on to a stunning 7-5 7-5 victory over Novak Djokovic in the semi-finals of the men's singles on Centre Court to set up a rematch of last month's Wimbledon final. Murray wept as he soaked up the adoration of the crowd and then leapt into the air in celebration of one of his finest wins and finest performances.
The Scot, who is now guaranteed at least a silver medal said: "The atmosphere was unbelievable, different to anything I've played in before and I've played in some big matches. Night matches at the US Open everybody says is the best atmosphere but it's not even close to what it was."
He went on: "It's one of the biggest matches of my career, one of the biggest wins of my career and one of the most emotional. I was so, so happy to win.
"You don't see me smiling that much but I haven't stopped smiling since I came off the court. Even afterwards, all the volunteers were so pumped, so happy, all the people around outside, it's just so different to what we normally experience in tennis. I think in terms of just enjoyment, it's probably the most fun I've had at a tennis tournament."
It was the day the Olympic tennis tournament really came alive, with Murray's victory coming in the gloaming because of Federer's titanic 3-6 7-6 (7/5) 19-17 win over Juan Martin Del Potro earlier in the day.
The world number one will present a formidable obstacle in the final, of course, particularly with the format changing to best of five sets.
There would be a certain irony if Murray were to win a title on Centre Court that was not Wimbledon, having spent so long trying to break his grand slam duck, but it would definitely not be second best for the Scot.
He said: "Before this tournament I would have said within tennis winning a grand slam is the most important thing you can do in your career, but within sport a gold medal is the pinnacle and, after what I experienced, it would be right up there with anything else I could achieve in tennis.
"I don't know how I would feel if I won gold but I know that winning a silver medal feels really good and losing a grand slam final feels terrible."
