The frequent occurrence of misjudgments by referees has made the outside world call for the reform of the referee system again, especially by means of scientific and technological means such as TV broadcast and playback, to increase the bottom line referee and ensure the accuracy of the penalty. Some media suggested that FIFA should add a bottom line referee and refer to the live big screen TV playback to ensure the accuracy of the penalty.
"Mistakes are also part of football matches" is the consistent creed of FIFA, which is why FIFA insists on not changing the current referee system despite its loopholes.
However, UEFA has prepared good suggestions. Taking the Europa League, which started in September last year, as a pilot, UEFA added two baseline referees, and finally achieved practical results in the battle between Liverpool and Benfica this morning. In fact, in the Europa League match between Liverpool and Lille last month, the referee referred to the opinion of the bottom line referee and fined Flohr for diving in the restricted area of the Red Army and gave him a verbal warning. However, the bottom line referee plays a key role in goal penalty, which is the first time this morning. When the linesman raises the flag to indicate offside and the referee doesn't see it clearly, the baseline referee is closest to the incident and has the best observation angle. His suggestion is certainly the most accurate and convincing. Therefore, when the referee made an effective penalty for the goal after consulting the baseline referee, the originally controversial parties quickly and unconditionally obeyed, thus ensuring the smooth progress of the game.
There will never be mistakes in football matches. Correcting mistakes after knowing them will not only damage the prestige of the referee, but also benefit all. The "new referee policy" piloted by UEFA is commendable.
