Dominic Thiem, having defeated Novak Djokovic in the quarterfinals of the French Open, next plays Rafael Nadal.
"It's a joke, how tough it is to win a Slam,” Thiem told reporters at Roland Garros. “Obviously now I beat Novak, but on Friday it is Nadal—the toughest opponent ever here in Roland Garros. Then, in the finals, there is another top star. That's why it's a Slam, it is because it's such a tough achievement."
