Extreme Heat Argument I don't think the world cup should even be held in Qatar. The world cup has always been held in the summer and that shouldn't change. The extreme heat in Qatar are not suitable situations for the players or even fans to be in; the risk of injury will increase.
The Speed of the Game The speed of the game would be affected. Soccer is a 90 min. Game with barely any pauses, stoping the game for a replay would affect the fluidity of the game. It would create more problems between the players and the referees. The referee would no longer be in control of the game and their job would be no longer be respected.
