FIFA Secretary General Jerome Valcke says he is concerned about Brazil's failure to progress in a number of areas ahead of the 2014 World Cup.
Valcke highlighted stadiums, transport infrastructure and hotels for fans as the main concern and said that organisers need to give themselves ''a kick up the backside'' if they have any hope of making the deadlines they have been set.
"I don't understand why things are not moving," Valcke said. "The stadiums are not on schedule any longer - and why are a lot of things late?
"You don't have enough hotels everywhere. You have more than enough in Sao Paulo and Rio de Janeiro, but if you think about Manaus you need more.
"Let's say in Salvador you have England versus Holland and you have 12% of the stadium English fans and 12% Holland - that's 24% of 60,000 fans. The way to go to the stadium and all the organisation of transportation has to be improved."
Valcke added that there were other areas of worry ahead of the tournament.
''In 2014 we will have a World Cup," he said. "The concern is nothing is made or prepared to receive so many people, because the world wants to go to Brazil. I am sorry to say but thing are not working in Brazil.
''What is the World Cup for Brazil: To organise the World Cup or to win the World Cup? I think it's to win the World Cup.''
