Although South African officials have dismissed concerns over preparations for the tournament – insisting the event will take place as planned – there have been worries some venues will be ready in time.
Speaking to BBC TV, Blatter said nations including the US, Spain, Japan, UK and Mexico could all step in to host the event if needed – although he remained confident South Africa would be all set come kick-off.
Blatter said: “Definitely we have a possibility to go somewhere else if something happens. It was the same case in Germany. Something can happen. A natural catastrophe or whatever, a big change in society - everybody against football.
“But for the time being the plan B is South Africa and the plan C we definitely must have a possibility to go somewhere else, but it must be a natural catastrophe.”
