Firstly, they will have such an opportunity very soon. Video replays are currently being tested in the Dutch Cup and FA Cup, and they will also be tested in test mode in several Bundesliga matches. It is assumed that the referees of the 2018 World Cup will already use them in full.
Why didn't it happen before? First, there was a purely legal point. Video replays could only be introduced with the consent of the rules committee. Its members are sometimes referred to as the Guardians of Football. There are representatives of England, Scotland, Wales and Northern Ireland, as well as some FIFA representative who has no influence on them. The committee is really very conservative and blocked this reform for a long time.
Secondly, the idea of video replays was not always clearly formulated. The referee cannot watch every joint, because there are many joints, and interrupting the match every minute is to kill the spectacle. On the other hand: a joint is, perhaps, a violation, a violation is a potential yellow card, two yellow cards are sending off, sending off is an influence on the course of the game. What to do? There was no clarity. There is no it, really, and now. What episodes will the judges watch? Key only? What is considered a key episode?
Third, the key argument against video replays was: "Football players play football according to the same rules as children in the yard." It was so. The rules by which you play the ball with your friends are very similar to those by which the Champions League is played. Except for the offside rule, which does not have such weight at the yard level for many reasons. Therefore, the committee considered the introduction of video replays to be redundant. And FIFA came up with compromise options, such as Hawkeye technology for determining a goal.
Because the governing bodies of football are very conservative. And also because it is sometimes desirable for them to influence the course of matches with the help of refereeing. Several other sports have already proven that introducing video replays is beneficial. And their experience should be taken into account.
They like to make false arguments against video replays:
AND what? Is there nothing else to see in football? Nonsense. Moreover, repetitions will not get rid of all mistakes.
So what? So no one says that this is a panacea. But which is better: 100% errors or 30%? I think the answer is obvious. Moreover, the wildest ones disappear.
It's not difficult to organize everything so that the inhibition is small. For example, so that the information to the main referee is reported by his assistant, who is sitting at the monitor and only in extremely significant moments - a goal, a penalty, a sending-off. The referees are now consulting with line assistants and a reserve referee, so nothing new will happen.
Video replays will already be tested in some tournaments, and I think that football will come to this entirely in the next 20-30 years.
No matter how it sounds, but football is a sports reality show. Naturally, this has been thought of many times, it has been discussed, but they don’t do that, because football should bring emotions to the audience. Thanks such judicial errors have something that can be discussed by fans. And you just have to imagine how at each controversial moment, violent emotions and worries will not be caused among the fans, but everyone will look at the scoreboard, eventually deciding that the judge was mistaken and continue as if nothing had happened.
