Great Britain's Johanna Konta has said that she feels "privileged" to be able to continue her run in the women's singles at the Olympic Games.
Konta needed three hours and seven minutes to record a 3-6 7-5 7-5 victory over Svetlana Kuznetsova on Tuesday, and the world number 13 has admitted that the win was one of the best of her career.
The 25-year-old told reporters: "It's the longest match I've had recently. I've been very fortunate that I've been part of some spectacular matches in my career and hopefully there will be more to come. But that definitely ranks up there just because it's my first Olympics.
"It was the first chance I had to really showcase such tennis in the biggest sporting event in the world so I feel pretty lucky and privileged that I get another chance tomorrow.
"Both of us had a lot of chances each way which is very normal for any tennis match. It's just about fighting each point individually and not looking too far ahead or too far behind."
Konta will face world number two Angelique Kerber for a place in the semi-finals in Rio de Janeiro.
