Alexander Zverev has been on the ATP Tour for over a decade and has won 24 titles in his career.
Zverev is yet to win a Grand Slam title, though, having made three finals at majors in the last five years.
He’ll continue his pursuit of achieving the feat at Roland Garros, which he will be preparing for after exiting the Hamburg Open, where Zverev lost to Alexandre Muller in the round of 16.
The German dropped to number three in the world following the conclusion of the Italian Open, meaning Zverev enters the French Open as the third seed.
Still only 28, he has plenty of years left to fulfil his dream of winning a Grand Slam, and won’t be thinking about retirement any time soon, but revealed what it would take for him to call it a day on his career.

Speaking in an interview with Adidas, Zverev said: “I always said that I don’t do this for the money. I do not do this to have benefits outside the court.
“I actually play the sport because I really love it. I love to play it and I love to train.
“You know how much I like to train. The moment I stop enjoying it, I won’t play any more.
“I will not continue playing just for other reasons. I will continue playing because I really want to.”
Alexander Zverev says he always thought he was going to be good growing up
When asked when he felt like he would become a good player, Zverev answered: “At a young age when you are a kid you kind of just dream of those things. You don’t really have doubt in you. That only comes after. That comes with age, I feel like.
“I always thought I was going to be good, I always thought I was going to win tournaments. I never thought I am going to be top 100 or top 50. That was never my goal.
“That was never my thing that I wanted to achieve, my thing was that I want to be the best, and that’s it.
“I think there’s one question mark I have, and that’s winning a slam, but even that, I do feel, honestly, that I am closer than ever and my level is better than it ever was.
“I have got to be myself in those positions, in winning positions, and at some point it is going to come naturally, I think.”
Zverev made the final of Roland Garros last year, where he was ultimately defeated by Carlos Alcaraz in the final.
He also had a near miss at the Australian Open this year, where he was beaten to the title by Jannik Sinner on Rod Laver Arena.
