Alexander Zverev may have just won the Montpellier title for his second career title, but that won't diminished his motivation for reaching the top of the game.

The ATP World Tour talked to his family to uncover his "healthy obsession" and learn about his incredible work ethic during the offseason to prepare for the 2017 Emirates ATP Race to Milan (the inaugural "Next-Gen" year-end tournament for players 21 and under). Though with a ranking of No. 18, Zverev may potentially make the ATP World Tour Finals in London.

"Borderline obsessive. I see it in all the top guys and Sascha has it. He has this healthy obsession to be great at tennis," said his trainer Jez Green, who wasn't the only one to talk about how the 19-year-old's mentality is one of his greatest strengths.

His older brother Mischa Zverev said that Alexander "literally wants to wake up everyday and play better than the day before. He wants to run faster than the day before. So he's very motivated which is good because I feel like that's the difference between really good players and the greats."

Zverev will have to focus everything he has because his next challenge is Dominic Thiem in the first round in Rotterdam on Wednesday.
