Football's governing body is confident that every chosen venue will be ready for the big kick-off in June - despite reported problems in Porto Alegre, in particular
Fifa is determined to ensure that Estadio Beira-Rio will host matches at the World Cup amid concerns over the venue's readiness.
The mayor of Porto Alegre, Jose Fortunati, recently expressed his fears that stadium renovations would not be able to be completed in time for the tournament, which starts in June.
Fortunati warned that the southern city may miss out on hosting matches if a bill to allow tax breaks for companies investing in temporary structures for the competition is not voted in.
"This is the point which matters in terms of holding the World Cup in Porto Alegre," he told Radio Gaucha.
"If the bill is not voted, we will not have the World Cup in Porto Alegre. This is because we will not have the resources to do it. We have no plan B. The only alternative is this."
When contacted by Perform on Tuesday, Fifa stated that it will do all that it can to ensure that work on all of the 12 stadia is complete for the finals and that the situation should be made clearer later this week.
A Fifa spokesperson said: "As said previously, the Fifa World Cup will be played in 12 venues. Fifa, the Local Organising Committee (LOC), the federal government and the respective host cities are working together this week in Rio de Janeiro to find solutions to the remaining challenges.
"There will be a detailed update on Thursday at approximately 12.30 Brasilia time [15.30GMT] following the LOC meeting at a media briefing in Maracana."
