Roger Federer has expressed his delight at reaching the final of the men's singles at the Olympic Games.
Federer beat Juan Martin del Potro in the longest match in Olympic tennis history to progress into the final, where he will face the man he beat just weeks ago in the Wimbledon final - Andy Murray.
The world number one and 17-time Grand Slam winner dedicated his win to his country, for which he has now guaranteed a first medal, but also paid tribute to his opponent after their epic bout.
"I couldn't be more happy and more pleased. It's a big moment in my life and a big moment for Switzerland because we don't have a medal yet. I hope that this also inspires other Swiss athletes for the Olympics now," said the 30-year-old.
"The level of play throughout was amazing, especially from Juan Martin. I've never seen him play so well from start to finish, particularly on grass. He should be very proud of his performance.
"I felt very bad for him at the net. It was an emotional hug we gave each other. It's not over for him yet. I hope he can make the turnaround and play a good bronze medal match."
Federer, who already has an Olympic gold medal in doubles to his name, is aiming to become only the third man, after Andre Agassi and Rafael Nadal, to win all four Grand Slams and an Olympic singles gold, completing the career Golden Slam.
