It is almost the end of an era.
Serena Williams, the 23-time Grand Slam singles champion, one of the greatest tennis players of all time and a sporting icon, is set to retire.
It is difficult to imagine tennis without the American legend, who has won all there is to win during her 27-year career.
From a purely sporting point of view, Williams will be remembered as one of the game's greatest competitors; an athlete who possessed the purest serve in the women's game and a never-fading desire to win.
She will also be remembered for speaking out against racism, pushing for gender parity and equal prize money, as well as her experiences of the healthcare system as a black woman.
