Canadian tennis star Felix Auger-Aliassime has parted ways with his longtime coach, Frederic Fontang, after more than a decade of collaboration. The decision, announced on Thursday, marks the end of a partnership that began when Auger-Aliassime was just 12 years old.
End of an era for Auger-Aliassime and Fontang
Fontang, a Frenchman, has been a constant presence in Auger-Aliassime's corner throughout his rise from junior prodigy to top-10 ATP player. Under Fontang's guidance, the Montreal native reached a career-high ranking of No. 6 in the world and captured four ATP titles. The 25-year-old said the split was a mutual decision driven by a desire for a fresh perspective.
“After 13 incredible years, Frederic and I have decided to go our separate ways,” Auger-Aliassime said in a statement. “I am grateful for everything he has done for me, but I feel it's time for a new voice in my team to help me reach the next level.”
Impact on Auger-Aliassime's career
Fontang was instrumental in shaping Auger-Aliassime's game, known for his powerful serve and aggressive baseline play. The duo celebrated numerous milestones, including a run to the US Open semifinals in 2021 and an Olympic bronze medal in mixed doubles at the Tokyo Games. However, recent results have been inconsistent, with Auger-Aliassime failing to advance past the quarterfinals in any Grand Slam event in 2025.
“Felix has the potential to be a Grand Slam champion, and sometimes a change is necessary to unlock that potential,” Fontang told reporters. “I wish him nothing but the best.”
What's next for the Canadian star?
Auger-Aliassime has not yet named a replacement for Fontang but is reportedly considering several high-profile coaches. He is currently ranked No. 12 in the world and is preparing for the upcoming hard-court season, which includes the US Open. The Canadian will look to bounce back after a first-round exit at Wimbledon last week.
“I'm excited about the future and the new energy this change will bring,” Auger-Aliassime added. “My goal remains the same: to win the biggest tournaments in the world.”
