Venus Williams is looking to win her sixth Wimbledon title when she plays Garbine Muguruza in Saturday's final, 17 years after winning her first.
The 37-year-old American is the oldest finalist at SW19 since Martina Navratilova in 1994 and victory would make her the oldest winner since Charlotte Cooper Sterry in 1908.
So, what keeps Williams going? What is it like to play against her? And what can Muguruza do stop her claiming yet another triumph on Centre Court?
Former world number one Kim Clijsters tells BBC Sport how it felt to face Williams on the other side of the net, and how it feels watching her from the commentary box now.
