We do have video which is why it is frustrating that "simulation" in all its forms is not punished. Until it is then players will always cheat. And until it is to are a fool if you do not do as others do to gain an advantage.
Is it the lack of crowds that's throwing up all these strange results. Today Leicester, Liverpool getting beat, Utd were beaten by a top 6 team, with 10 men. If you go to 10 men you have to play on counter attack which didn't happen
In the past I would have cringed at a Spurs player going down that dramatically. But in the modern game it seems that this is condoned by the officials and if your players don't do it they are not doing right by the team. So I have to accept that my team's players will look bad but until the authorities use video to stamp it out you have to do it to compete.
