Holger Rune produced one of the shocks of the tournament so far as he beat Stefanos Tsitsipas at Roland Garros before confidently declaring: 'I haven't won it yet.'
The unseeded 19-year-old Dane was a big outsider against world number four Tsitsipas, who appeared to have been handed a kind draw at the outset of the tournament.
However, Rune proved that analysis wrong as he beat last year's finalist 7-5, 3-6, 6-3, 6-3 in what was probably the biggest upset of the men's singles so far.
In reality, there was little in the way of luck involved in this win, with Rune the better player throughout.
"We are only in the quarter-final so we haven't won it yet," Rune declared after the match.
"I'm so grateful and so happy to be playing on this court.
"I was very nervous but at the same time I knew that if I go away from my tactics I will lose for sure.
"I tried to play my plan and it worked out so well at the end. It's just so great to still be here.
"It was part of the tactic to be as aggressive as possible. [Stefanos] Tsitsipas attacks every ball. I had to be aggressive, play fast, and I really like playing the drop shots. It worked out and I'm really happy."
Rune was brilliantly supported by his mother in the crowd on Philippe-Chatrier, and he admits he believes that gives his game an extra edge.
"I get so emotional when I talk about my family and coaches," he said.
"But my mum is why I'm here today. I am so grateful to have a top team helping me in this situation."
Holger Rune will have to be at his best in the quarterfinals too, where he will face the eighth seed Casper Ruud.
