#5 Lack of technology
There are countless instances where wrong decisions by the referees have decided the outcome of the game. Referees have to conduct the game in a fair way and not be the hero of the match by making unnecessary bookings or take vital decisions at crucial moments in a match. That's why technology is very much needed in the modern game which will help the officials to reduce their mistakes and not give undue advantages to one of the team.
Although with the adoption of goal-line technology, the footballing world has taken a massive stride towards eliminating one key area of human error, other avenues such as the review of a penalty among others need to be explored and implemented.
Other sports like Rugby and Hockey are great examples of how technology can aid in the betterment of the game and it is absolutely irritating for the supporters when a wrong decision by a referee becomes the difference between winning and losing for their team.
