In his post-match press conference, Holger Rune expressed hope that more young Danish players would break through on the tennis circuit. Rune also urged young players to "keep believing" and said he was always available for advice.

"Yeah, I hope it's going to change. It already changed a little bit since I went into the top 30," Rune said. "There is more focus on tennis in Denmark in general. We obviously had Wozniacki, but I'm kind of the first male player on the tour. It's great. You know, more focus on Danish tennis is great."

"It's good to hear the young kids can start playing more, going to more tournaments, and traveling more. Just I want to say to them: Just keep believing in yourself. They can always ask me for some advice if they want."

A "super excited" Holger Rune also stated that he would be traveling to Turin for the Nitto ATP Finals, where he is the first alternate. While wishing health to the top eight competitors in the tournament, the teenager said it would be "awesome" if he got to play.

"Of course, I'm going to go to Turin. I'm one out. I mean, I wish all the players that I'm not going to play, because I wish them to be healthy, but at the same time, it would be awesome if I got to play," Rune said. "I didn't expect that at all four or five weeks ago but now I'm here. I'm super happy about how I officially ended my season, and if there possibly are more matches, I'm just super excited about it."
