London: Serena Williams joined the Wimbledon tributes to ailing former South Africa president Nelson Mandela on Tuesday, claiming it was one the greatest moments of her life when she met the anti-apartheid icon.
The American described Mandela, who is critically ill in a Pretoria hospital, as an "amazing" man from whom lessons can be learned.
"It's a really sad time I think for everyone. I feel like Nelson Mandela lived a really amazing life. Meeting him was probably one of the best moments of my life, and it will be a great loss," said the Wimbledon champion.
