FIFA was prompted to ask for another test after Sunday's game where not all the seats required for the World Cup were installed in time. FIFA requires the venue to seat 68,000 spectators but only 40,000 were used for Sunday's match. The other 28,000 seats are temporary and will only be used during the World Cup.
The second test game will take place on 29th of May between Corinthians and Cruzeiro. Some problems occurred during Sunday's test game due to an unfinished roof that forced fans to scramble for covered seats because of heavy rain. Part of the roof that will cover the rest of the seats at the stadium won't be finished until after the World Cup, according to the local media.
