Sepp Blatter has reiterated the need to integrate goal-line technology into world soccer.
Speaking to FOX Soccer, FIFA's president said the game's governing body is in the last phase of testing potential solutions, with accuracy and level of complexity determining whether a system will be implemented.
Blatter confirmed Hawk-eye, the technology used in tennis and cricket, is "one of the companies" being tested, though he explained the challenges posed by soccer could prove more difficult than the requirements of other sports.
"(Soccer has) four dimensions," Blatter explained. "We really are on the high mathematic, and it is not so easy, but I'm sure that we will find at least one system, or two systems, that will answer our questions."
Blatter then outlined the standards his organization will use to find a qualified system.
"The question is the accountability, the precision. Second, the immediate information: If it's a goal or not (a) goal. And third, a not too complicated system.
"And I'm sure that we will find it. If there is one, it will be accepted."
Calls for goal line technology were heightened after the 2010 World Cup, where officials failed to award England's Frank Lampard a goal in a Round of 16 defeat to Germany. Replays showed the midfielder's first half shot bounced behind goalkeeper Manuel Neuer's goal-line after hitting the crossbar.
Speaking to FOX Soccer (in footage released Monday night), FIFA president Sepp Blatter discusses why US soccer leagues need to shift to the competition calendar used in Europe.
Blatter underscored the need to deal with the problem as soon as possible.
"We have to put it in there. We cannot go on saying, 'OK, it happens every four years' or whatever. No, we have to go in.
"I know there will be some opposition, even inside FIFA," Blatter explained while identifying the limits to which technology should be used.
"We have goal-line technology, yes, but no more. On the field of play: no technology."
While such a stance would preclude technology being used to review diving, Blatter conveyed a hard line stance on simulation.
"I am totally against diving and in favor of a very harsh punishment. The first time, a yellow card. But the second one - even if it's another diver - out. And then it will stop."
Alluding to his playing days, where he played in the top division of the Swiss amateur league, Blatter equated diving to cheating, distinguishing simulation from other acts which intentionally break rules.
"I was not a diver because I don't like water. I am not a good swimmer.
"(Divers) should go to water sports and the summer Olympics … That's a diver.
"It's a shame … because it's cheating, and this is cheating in the spirit.
"You know you can cheat a little bit in the field of play. You can, you did. You can strip a shirt or pull a leg. This is obvious. You can see it.
"But if you are diving, that's not good. It is something wrong in your spirit."
