Rune is the world's top-ranked junior, and has been taking his first steps on the professional circuit over the past year. The Dane was born in April 2003, just two months before Federer won his first Grand Slam.
It's not just Rune's long-term goals that are ambitious; he has also set some lofty goals for himself in 2021. The 406th-ranked 17-year-old wants to qualify for the French Open and break into the top 100 by the end of the season.
"The idea is to qualify for the main draw of the French Open and I think I have a great opportunity to score points here to get closer to the goal of qualifying," Rune said. "Then by the end of the year I would like to get into the top 100. It's a big step, but I think I can do it. My dreams are to win several Grand Slams, reach No. 1 and be like Roger Federer."
