Indian badminton star PV Sindhu says she is calm and focused after defeating Yihan Wang of China to book her place in the semi-finals.
A 2-0 victory in the quarters saw the 21-year-old from Hyderabad through to the last four, and doing so on the Olympic stage made it "one of the best moments" of her fledgling career.
"I was just thinking about the game," she said. "If you play really well you will automatically win the game, and a medal."
Sindhu didn't have an easy clash against her experienced Chinese opponent, who won silver at London 2012 and put up a strong fight in Rio.t
"There were big rallies, she was attacking well," Sindhu added. "My smashes were going out initially. She did not leave and she was lifting everything. It was very close.
"She's an experienced player and world number two. Nobody expected me to get easy points. I was really patient and I was ready for everything, which I feel was the turning point.
"I never thought I would lose this, because any moment anything can change. I'm just focused on my match and the next match, the semis. I hope I can give my best."
Sindhu will face Nozomi Okuhara of Japan in the semi-finals, hoping for her shot at gold in the final against either Carolina Marin of Spain or Li Xuerui of China.
