Lawyer Michael Garcia is leading the investigation by the Ethics Committee into whether claims of corruption surrounding Russia's 2018 and Qatar's 2022 winning bids hold any truth.
But FIFA secretary general Jérôme Valcke wants the investigation to be speeded up.
"[The report] should come now, we should have a final, final position and the best would be even before the World Cup 2014 and then just work on the next World Cup," Vlacke said as he concluded a tour of stadiums in Brazil ahead of the competition.
"We are working on the organisation of 2018 from now, as we are working with Qatar since the first day they received the organisation of the World Cup.
"We need to be able to work in an environment which is, let's say, a safe one."
Garcia's investigation has seen him recently in Zuirch, Switzerland interviewing members of the Executive Committee about events leading up to the announcements of the successful bids in December 2010.

He was appointed two years ago, with claims of secret deals and corruption surrounding the two bids continuing to swirl since.
Earlier this week, Mark Pieth, who was asked by FIFA in 2011 to suggest improvements to its corporate governance, urged football's governing body to resolve allegations surrounding the bids.
"The ethics committee should not rest until there is a conclusive answer," he wrote in a report sent to all of FIFA's board members.
"If FIFA is to emerge from the scandals of recent years it must now produce a convincing and transparent answer to any issues relating to hosting decisions, either to confirm that the suspicions are, sadly, well founded or to demonstrate that they are groundless."
