FIFA president Sepp Blatter announced earlier today that Rio de Janeiro, Sao Paulo, Manaus, Fortaleza, Natal, Recife, Salvador, Brasilia, Cuiaba, Belo Horizonte, Curitiba and Porto Alegre will be the 12 cities to host the tournament in five years' time.

In Nassau, the capital of the Bahamas, FIFA's executive committee opted to reject applications from five other potential venues - Florianopolis, Goiania, Campo Grande, Belem and Rio Branco.

Teixeira insisted he was focussed purely on the successful dozen cities, rather than formulating back-up plans.

"I don't work with possibilities," he said. "The decisions were very well made and I am sure the venues will manage to complete all we have planned.

"I would like to make a comparison - we have just passed an exam. We have five years' time to be given the official diploma of the course."

Blatter, meanwhile, is sure FIFA made the right choice by naming Brazil, who were the only candidates to host the tournament.

And he revealed: "In the very beginning, 10 cities were going to be chosen, but thanks to the influence of Ricardo Teixeira and the interests of the country, we agreed increasing the number to 12," said Blatter.

The iconic Maracana stadium in Rio de Janeiro will welcome the final match, while Belo Horizonte and Sao Paulo will fight to stage the opening game of the finals.

The president of Sao Paulo FC, Juvenal Juvencio, believes the Morumbi stadium is the right option for that game.

"There is no area in Sao Paulo better than Morumbi (the neighbourhood in which the stadium is located). We have hospitals, the Congonhas airport and now the creation of a new line of underground and other things," he said.

"Belo Horizonte has only one five-star hotel, while we have a lot here. Morumbi is 84% ready and we need to make little changes.

"We'll spend 130 million reais (US dollars 66million) thanks to the money from different agreements with the club. We will not spend state money."

The governor of the state of Sao Paulo, Jose Serra, added the city will be ready to host the opening match and asked the federal government for financial support, especially for increasing the capacity of airports.

Serra said: "I am confident we'll prepare the city very well, even for the opening match.

"I am sure Sao Paulo will follow the responsibilities to help the state gain the opening match of the World Cup. I hope the federal government will also do their job, especially over airports."
