Work on most of the 12 stadiums has been hit by increases in costs with the worst case in Sao Paulo where construction of Corinthians' new ground, earmarked for the opening match, is still to start three years before the finals.
"FIFA has been systematically following Brazil's preparations and knows the effort the country is making to comply with all the demands," Silva told the Radiobras programme "Good morning minister" in an interview.
"I believe that as we move from 2011 into 2012 the perception of Brazil will change because work on the stadiums at that stage will be very different. I'm confident of that turning point."
Silva confirmed that President Dilma Rousseff's decision last month to turn over the improvement and running of airports to private firms had been well received by world governing body FIFA, which had criticised transportation in Brazil.
"It's an investment of 700 million focused on passenger terminals. With this investment we'll have adequate tourist terminals for the World Cup," he said.
