" What was inexcusable is the reaction of the Leeds player who reacted as if he had been hit with an axe. Again, a deliberate attempt to deceive the referee which went unpunished. Until the game gets to grips with this ludicrous simulation there is no hope for it. "
LateTackle's words are correct. I'll avoid dodgy analogies and incorrectly quoting Law, but 100% support this.
Video technology is having an "interesting" impact on the game through VAR. Video technology could eradicate this ludicrous simulation if there was the will to do so. The truth, however, is that if the circumstances had been reversed, the Arsenal player would have done exactly what the Leeds player did do.
Its really up to the teams, players, managers, etc. Do they want to get it out of the game or not?
They didn't help themselves when they didn't punish Lamela for his similar playacting against Martial earlier this season.
