Success had followed his Davis Cup heroics with his biggest Challenger title, a 125k event in Oerias, Portugal last month on clay, which lifted him to the brink of a top-100 breakthrough.
Moller never envisioned he would go on to take the sport seriously as a career.
It was more a case of having stumbled into something he never even considered himself that good at in the early days.
“I mean nobody in my family played tennis. I think it was just I played for fun with my dad. We used to play in parking lots and stuff like that,” he said. “I was really s**t actually for a long time. I don't know why I kept going. Honestly, I don't know. I think I just liked doing sport and then I just found tennis to be the most interesting one.”
Now the No.2 Dane behind the highly credentialed world No.10, Holger Rune, a player whom he grew up playing alongside, that Davis Cup Qualifying tie was a full-circle moment for the pair, having also represented Denmark in the junior team competition.
Moller though was determined to forge his own path.
