Serena Williams has never been shy in citing her faith as one of the factors behind her competitiveness as a tennis player, helping her become one of the greatest of all time.

The 41-year-old, who won 23 tennis grand slam tournaments during her career, has seen her faith become a talking point on a number of occasions.

When her daughter Alexis Olympia was approaching her first birthday in 2018, Williams took the opportunity to say that she and her husband Alexis Ohanian would not be throwing a party as it would be against their faith.

Williams and Ohanian are Jehovah's Witnesses and the former U.S. Open champion said at the time: "Olympia doesn't celebrate birthdays. We're Jehovah's Witnesses, so we don't do that."
