Fifa will have further discussions over the use of extra officials
Fifa are considering further trials into the use of additional assistant referees, with a view to potentially using them at the 2014 World Cup.
Uefa experimented with the use of assistant referees behind the goals during 2009/10 Europa League.
"One thing we are discussing is two additional assistants," said Fifa secretary general Jerome Valcke.
"This is to support referees to make decision-making easier and to have more eyes helping him to make decisions."
There have been a number of controversial incidents at the 2010 World Cup in South Africa.
Brazil striker Luis Fabiano's second goal in his side's 3-1 Group H win over Ivory Coast had a strong hint of handball, while the United States had what seemed to be a legitimate late third goal ruled out in their 2-2 Group C draw with Slovenia.
"We can talk about refereeing decisions which, when you looked at them after the game, you could say were perhaps not good decisions," said Valcke.
"We didn't say you could have a zero fault system in the World Cup. We knew this is where criticism would come.
"Additional assistants could happen in 2014 to make sure these kind of things are not happening."
However, Valcke ruled out the potential use of video technology, saying: "that is definitely not on the table today".
Valcke also insisted that there are no plans to reduce Africa's allocation of places at future World Cup finals, despite the poor showing from the continent's teams in South Africa.
Of the six African sides competing in the tournament, including hosts South Africa, only one - Ghana - progressed beyond the group stage.
"We have 32 teams, and we will have a meeting of the organising committee of the 2014 World Cup when we will discuss the rules and regulations," Valcke said.
"But there is no discussion at all about the number of slots per confederation. Anyone who is saying that is wrong.
"We need to continue supporting African football."
