Input: Joost van der Westhuizen was given between two and five years to live when he was diagnosed with motor neurone disease - that was more than four years ago. On Wednesday, frail and fragile but as alert as ever, he achieved a dream of joining his team-mates from South Africa's 1995 World Cup final victory to mark the 20th anniversary of their achievement. It was a win that immortalised them all in the annals of history, but Van der Westhuizen more than most. He provided the wily pass that led to Joel Stransky's match-winning field goal in extra-time that gave the Springboks the first World Cup they were allowed to compete for after Apartheid saw them shut off from the global sporting community.Joost van der Westhuizen is battling with motor neurone diseaseFormer scrum-half was key man in South Africa's 1995 World Cup winHe attended the 20th anniversary of his country's great victory in a wheelchair and looking frailFormer No 9 continues to fight to help fund the finding of a cure for MND
