FIFA, football's global governing body, along with those bodies running the game at regional and countrywide levels are gradually introducing more technology into the game in a bid to assist referees, prevent incorrect decisions and enhance the game's image.
Yes: Technology is great for football
Anything to help referees get more decisions correct is a good thing.
The 2018 World Cup showed the benefits of VAR
VAR and goalline technology at the 2018 World Cup in Russia worked well.
Football was fine without technology for hundreds of years. Why introduce it now?
Football does not need technology to prosper
Introducing technology would allow for interruptions to take place during a game. This may interfere with the momentum and provide teams with an unearned second-wind. Furthermore, longstanding football traditions would be broken.
