Gael Monfils has announced he will retire from professional tennis at the end of the 2026 season. The world number 53 has struggled with injuries in recent years and he was forced to retire from last month’s Chengdu Open with an ankle problem. “The opportunity to turn my passion into a profession is a privilege I have cherished during every match and moment of my 21-year career,” Monfils wrote on Instagram. “While I came close, I never did win a Grand Slam during my career,” continued Monfils. But the Spaniard and world number two Jannik Sinner have won nine of the past 10 Grand Slams between them.
