Many leading sports stars have paid tribute to Nelson Mandela following the death of the former South African leader at the age of 95.
Former South Africa rugby union captain Francois Pienaar famously received the William Webb Ellis trophy from Mandela after the Springboks beat New Zealand in the 1995 World Cup final.
Pienaar said: "The enormity of his impact is very difficult for me to describe.
"The impact he had on me as an individual - I've been very blessed, I was at the right place at the right time, more so than any Rugby World Cup captain before me and after me.
"What other President would have picked up the phone and said 'Hi Francois, how's the team doing - are you all okay?
"But the team - what he did for the team was wonderful to watch - that air of confidence that he brought with him and that unbelievable humility that Madiba had is something that rubbed off - and I never thought he would wear a Springbok jersey!"
