Odegbami has defended the Nigerian bid

The final bid documents are being put together for submission to Fifa before the expiration of their deadline, which is at the end of September.

South Africa, Tunisia, Morocco, Libya and Egypt are the other nations that have declared their interest in staging the tournament, which will be hosted by an African country for the very first time.

Nigeria's bid has failed to win the full support of the country's government but bid committee chairman Segun Odegbami said they are determined to make the World Cup dream come true.

"Nigeria's bid is as solid, strong and serious as ever and nothing is stopping it," Odegbami said.

"There have been a few problems from government and some fans but such things cannot distract the bid.

"We have not had enough support from government even though they inaugurated us, but they've remained silent for some time.

"However, they have given us a responsibility to perform and we must carry it out."

Odegbami said criticism from fans that the Nigerian bid was not a serious plan had not helped matters.

Earlier this year, Fifa president Sepp Blatter rejected a Nigerian plan to host the tournament with Ghana, Togo, Cameroon and Benin.

But the Nigerians have said that they will now act as sole hosts.

"All football matches will be played only in Nigeria but our regional brothers will be involved in the social and economic aspects of the tournament," Odegbami said.

"Visitors can stay in hotels in any of the countries and travel regularly to Nigeria to watch matches.

"This will help achieve our regional economic agenda and in this way, we can call our plan a true African bid."
