He is the first man from his country to ever reach the quarter-finals of a grand slam.

Talking about defeating the legendary athlete, an elated Tsitsipas said, "I'm the happiest man on earth right now. I agree with you (that I looked like I could win the match). You have to believe in yourself. Roger is a legend in the sport, I have so much respect for him. He's showed great tennis over the years. I've analysed him since the age of six. It was an honour to be facing him. I cannot describe it.

"I was too slow (in opening service game), but I wanted to take my time but sometimes the referee reminds you, you have to be on time.
