In the first round of the Europa League in 2009-20 10 season, fans all over the world found an interesting phenomenon: the number of referees wearing bright yellow on the court changed from the traditional three to five (plus the fourth referee or official on the sidelines, it is six referees). This five-referee system advocated by Platini was officially implemented in UEFA.
Compared with the traditional three-referee system, the newly added two referees mainly stand near the bottom line to help referees improve the accuracy of penalty in the penalty area. In this way, the two assistant referees, also known as linesmen, need to narrow their monitoring scope and just move around the sideline to become real linesmen. The two newly added referees should be called "bottom line referee" or "penalty area referee", and the name of the fourth official outside the court has changed the most. They will no longer be the "fourth official" but become the "sixth official".
Platini put forward the idea of five referees system, because on the court, especially in the penalty area, there is always great controversy about penalty kicks. Adding two "penalty area referees" staring at the penalty area will undoubtedly help improve the accuracy of penalty in the penalty area. In fact, before the UEFA Cup, the five-referee system appeared, and the U- 19 European Championship held in Cyprus in 2008 was also implemented, but it was indeed the first time in an adult-level competition.
From Europa League to Champions League
The bottom line referee pays attention to controversial events.
The bottom line referee has been experimenting in the Europa League for one year and the effect is quite good. Since the 20 10-20 1 1 season, UEFA has applied it to a larger stage-the European Champions League, which is the most concerned football club event in the world, and has made the five-person referee system and bottom line referee more deeply rooted in the hearts of the people.
The establishment of bottom line referee not only increases more jobs for football referees, but also improves the fairness of law enforcement in football matches. In many games, you may think that the bottom line referee is a bit redundant, because compared with the referee and linesman (frequently raising the flag to indicate offside), the bottom line referee does not have many opportunities to show his face. But as long as the bottom line referee shows his face, there must be a major controversy near the restricted area and the goal line. In the best position, he will prompt the referee in time and make the right penalty. This is the role of the bottom line referee.
Those famous controversial events in the history of football: 1966 World Cup unresolved goal, 1986 Diego Diego Maradona's handball, 2009 World Cup qualifier Henry's handball, 20 10 new World Cup unresolved goal and 20 12 Serie A AC Milan VS Juventus' top goal battle as long as the bottom line referee.
In addition, the appearance of baseline referee has played a great role in preventing diving. A referee is staring seriously at the restricted area on the bottom line. At this time, if you want to cheat a penalty by diving, you need to pay attention. And for the foul in the restricted area, the bottom line referee can see clearly. In previous games, there were always some obvious penalties but the referee didn't award them. This is only because the referee is too far away to see clearly, but with the help of the bottom line referee, this problem will gradually decrease.
