HQGaël Monfils, one of the most veteran active players in the ATP circuit, has announced his retirement from tennis. But it will not be this year: the Frenchman still has plans to compete throughout 2026, meaning he could be playing his last professional tennis match aged 40 (he recently turned 39 on September 1). Since turning pro in 2004, Monfils has won 13 titles, including three ATP 500 titles. Now, after celebrating my 39th birthday just a month ago, I'd like to share that the year ahead will be my last as a professional tennis player", he posted on social media. Though this game means the world to me, I am tremendously at peace with my decision to retire at the end of the 2026 tennis season".
