However, Herbert has been making noise in the ATP singles circuit, having secured wins over the likes of Dominic Thiem and Daniil Medvedev in 2019.

“I now consider myself a singles player that plays doubles.” says Herbert. "I really do get mad when I hear that I’m just a doubles player".

With retired ATP professional Fabrice Santoro as his coach, Herbert has made a remarkable leap due to his ambition and discipline. Santoro joined his team almost two years ago, and is the first to recognize his student's emerging talent and drive.

"When we first started working together he was around No. 100-110 in the world,” said Santoro. “We never thought in the first year he'd stop playing doubles at a Grand Slam, but now that he has broken into the Top 40, the ambition is different. He trusts his game and is stronger. We tried to make him stronger in the legs, with better footing on the ground, because if he is stronger in the legs, he'll be more aggressive from the baseline to the net. Before he was a little weaker in the legs, and he struggled moving to balls.”

Herbert's hard work has translated to the court, as the 29-year old reached has three ATP singles finals - Winston Salem in 2015, Shenzhen in 2018 and Montpellier in 2019. Although he is yet to win a singles title, the Frenchman believes he is on the right path.

“I’ve felt for the past few years that I’ve gotten better in singles, particularly over the past 12 months since Roland Garros,” admits Herbert. “I want to get better in practice and learn from my matches.”
