It has been repeatedly claimed that construction work on the country's selected tournament venues is running behind schedule and that planned infrastructural updates might not be ready in time for the big kick-off in just over two years' time.
However, Del Nero insists that Brazil will follow through on the promises it has made to the game's governing body but argued that meeting every single stipulation is not a requisite for a successful event.
"I'm sure the government will meet its obligations," the Sao Paulo Football Federation president told Radio Estadao/ESPN.
"President [Sepp] Blatter has already held talks with President Dilma [Rousseff] and the government will certainly fulfill all of its obligations.
"To stage a good tournament, it must meet all of Fifa's requirements, but you can not do everything that Fifa asks.
"The organisation knows that you can not do everything because of laws that exist in Brazil. If you do 80% [of what's asked], it is good [enough]."
Del Nero has only just been appointed to Fifa's Executive Committee, having been appointed to his position following Ricardo Teixeira's recent decision to end his involvement in the administrative side of the game for "personal reasons".
