Jiri Lehecka has made a significant coaching change by hiring Frederic Fontang, who previously coached Felix Auger-Aliassime. This decision comes just weeks after Fontang ended a decade-long partnership with Auger-Aliassime, during which he guided the Canadian to a career-high ranking of world No. 4. Lehecka's move reflects his ambition to elevate his game and build on his potential as he seeks to make strides on the ATP Tour.
