The grandson of Nelson Mandela has claimed FIFA have put "extreme pressure" on the former South African president to attend tonight's World Cup final.

Mandla Mandela, who revealed the final decision on whether his grandfather would attend the match between Holland and Spain at Soccer City would be made by Mandela himself and his family, also said the world governing body did not "understand the family's traditions and customs".

Mandela's great granddaughter Zenani Mandela died in a car accident on the eve of the tournament and Mandla Mandela explained the family should be left alone to mourn her loss.

"The family has really taken a step back from a lot of activities and we've been mourning the loss of Zenani," Mandla Mandela told BBC Radio Five Live.

"So we've come under extreme pressure from FIFA requiring and wishing that my grandfather be at the final today.

"But I think that decision will solemnly lie with him, how he wakes up today, how he feels, what his medical team says, but as well his family.

"They (FIFA) said that (president) Sepp Blatter wished that my grandfather comes out to the final.

"I think people ought to just understand the family's traditions and customs and understand we've had a loss in the family and we are in mourning and that for me would be enough reason to leave the family to be for now.

"Their focus is having this world icon in the stadium, yet not really paying attention to our customs and traditions as a people and as a family."

Blatter said in a pre-recorded interview he hoped it would still be possible Mandela might be able to make an appearance at the final.

He told the BBC Radio Five Live's Sportsweek programme: "If you cross figures then it is possible at the beginning of the match or just at the end of the opening ceremony he may be present on the field of play."
