Fifa president Sepp Blatter has admitted that the stadium due to host the opening match of the 2014 World Cup in Brazil will not be ready until mid-April.
Two construction workers were killed last month after a crane collapsed onto the stadium.
The opening match of the tournament is due to take place on June 12 which leaves little room for error in the bid to finish construction.
Speaking at a news conference in Salvador, Blatter admitted there was "no plan B":
"It will be ready in mid-April, it is a question of trust that it will be done.
"God and Allah willing no more accidents shall arise and the reconstruction can restart as soon as possible. For the time being there's no plan B."
