Jerome Valcke, secretary general of Fifa, soccer's governing body, is in Brazil for his latest inspection of 2014 World Cup host cities, with serious question marks hanging over whether the final six stadia will be completed by the December deadline.
Valcke was in the southern city of Porto Alegre yesterday, and moved onto Cuiaba today, where local organisers are still trying to finalise a bidding process for the seats at the new stadium.
Problems also emerged in Curitiba last week, when work on the Arena da Baixada stadium was suspended after a judge in a labour tribunal ruled there were safety concerns.
Brazil will use 12 stadia at the World Cup and of the six yet to be completed, five were less than 90 per cent finished by September, according to recent government numbers. The venues with the most advanced work were in Natal and in Sao Paulo, venue for the World Cup opener on June 12.
The stadium in Cuiaba was set to be completed by the end of the year but the problem with the seats has prompted concerns. Local officials were forced to cancel the initial bidding process for the seats after public prosecutors alleged they were overpriced, prompting a rush to find a new supplier.
The new seats are due to be delivered by December 20, leaving little room for manoeuvre considering Fifa's completion deadline.
In Curitiba, organisers are still trying to reverse a judge Lorena Colnago's order that suspended construction after an inspection team deemed the site unsafe for workers. The stadium is due to stage four matches during the tournament.
