They don't even have to do that. Just red card their asses and the shit will stop. I don't have a problem with officials fucking up (within reason. Officials are going to make mistakes and if they make to many of them, you fire them.). Instant reply calls ussually cause more problems then they solve by screwing up the flow of the game so I dont have a problem with not allowing reviews. We've done it in American Football and by and large it hasn't worked. I just take officiating mistakes philosophically. It's just part of the game. You never know which way the ball will bounce.
But stopping misbehavior by atheletes is easy. Toss them from the game if they flop or are disrespectfull to an official or otherwise disrupt the game.
In major league baseball if a player curses and an umpire hears it. He's thrown out of the game. If he argues with an official, he's thrown out of the game. If he disrupts play, he's thrown out of the game. If he cheats, he's thrown out of the game. The line is real clear and if you cross it, you get tossed. I dont' see why FIFA can't do that either?
