Or VAR gets used, if a foul was committed the player gets a red card but if a player was play acting the player who would have been sent off gets one free kick to the offending players haw maws. It would certainly stop play acting.
Think it's about time there was retrospective punishment for people who pretend to be injured like that ass hole who got tanser sent off the amount of cheating and diving that goes on even from ours is ridiculous not being touched but roll about as if they have been shot .
