He said work on venues in Recife, Brasilia and Rio de Janeiro (the redeveloped Maracana stadium) is due to be completed by the end of this month. There will be 12 grounds used at the 32-team World Cup, which will host 64 matches -- four times that of the eight-nation Confederations Cup.
"It is impossible to expect this to happen in the shortened preparation time -- in most cases, less than two months instead of the scheduled six -- due to the compromises we made with the cities," Valcke said.
"I want to reiterate: this will be impossible to repeat for the FIFA World Cup, and has been acknowledged by the federal government and LOC. The deadline for the FIFA World Cup stadiums delivery stands firm as December 2013. There will be no compromise."
