i don't understand , the actual play time in each half is between 20-25 minutes , that means almost half the full 90 minutes is wasted with ( goal kick , free kick , corner , fouls , injuries , throw ins , subs , etc etc etc ) so they can't waste 5 seconds to review a crucial call that can effect the outcome of the result ? if every single person on the planet watches the instant replay and immediately knows that it is a wrong decision then why can't they let a fifth referee in front of the monitor to inform the main referee instantly by talking to him through the ear piece that this or that happened ? they wasted MILLIONS for the goal line technology although it could have done through replay ( there was an option for the referee to choose in the confederation cup ) but until now they are wasting those poor teams efforts who worked hard all these years along with their fans because " they don't want to waste time " by allowing ridiculous mistakes over and over again with the golden excuse " i couldn't see it because it was too fast for my eyes or my vision was blocked " well .. almost half the 90 minutes are wasted and there are 30 cameras with most that have super slow motion all over the freaking pitch ... USE THEM !!!! heck give that fifth referee ( experienced , age doesn't matter since he isn't required to run ) a 100" Ultra HD TV ( FIFA are rich aren't they ? ) and let him see all those incidents with Super slow mo and immediately inform the main ref what happened , will there be any more complaining going on afterwards ? this is a solution to everything and should've been implemented ages ago , yet they still don't want to use it for strange reasons ... and for some who are saying " well you can't use it everywhere " well actually you can , almost every single game has video coverage in all countries and heck even if you say " well we need good cameras with slow motion and high quality , well when Tennis first used hawk eye did they use it on every single court ? nop only 1 or two and even till now they only have a couple of courts with that technology because if they can at least use it in some games where it makes a difference then why can't they ? we are talking about football , the riches sport in the world , surly they can afford 1 extra referee ( not those two useless ones on the side on the goal that don't have any jobs what soever and just stand there doing nothing the entire time even if incidents are directly in front of them ) , all you need is to give him a tv and that's that , instant report of what happened seconds afterwards to the main referee and no more mistakes.
