JOHANESBURG-Nelson Mandela has Sunday evening turned up at the World Cup closing ceremony to greet his fans. The former South African president was smiling as he was driven across the pitch in a golf cart with his wife, Grace Machel. Earlier, one of his grandsons said Fifa had put Mr Mandela under "extreme pressure" to attend. Mandla Mandela said the engagement would be "strenuous" for the 91-year-old, who is increasingly frail. The crowd at the Soccer City stadium in Soweto, Johannesburg, welcomed Nelson Mandela with a mixture of cheers and vuvuzela blasts. The anti-apartheid icon shook hands with officials before leaving the field a few minutes later.
